4.2 The standard temperature/time curve(post flash-over fire)
When applied as a basis for testing,the standard temperature/time relationship shall be applied for the full duration of the test.The relationship,which is a model of a fully developed fire in a compartment,is given by the following relationship:
T=345log10(8t+1)+20 (1)
电话=345log10（8T+1）+20 （1）
where
哪里
t is the time from the start of the test in minutes (min);
T is the mean furnace temperature in degrees Celsius(℃).
NOTE Further details relating to the practical application of this curve and other test parameters,
e.g.tolerances,are given in EN1363-1.
例如公差， 在 EN1363-1 中给出。
4.3 The slow heating curve(smouldering fire)
The smouldering fire test shall only be used if it is expected that the fire resistance performance of the element may be reduced by exposure to temperatures associated with the growth stage of a fire. It is,therefore,particularly relevant to elements whose performance may be dependent upon high heating rates below approximately 500℃(as provided during the standard temperature/time curve) for achievement of their classifications(i.e.mainly reactive or intumescent products).
The slow heating curve is given by the following relationship:
for0<t≤21
T=154t0,25+20 (2)
fort>21
堡垒>21
t is the time from start of test in minutes(min);
t 是从测试开始的时间 ，单位为分钟（min）;
T is the mean furnace temperature in degrees Celsius(℃).
T 是平均炉温，单位为摄氏度 （°C）。
NOTE Further details relating to the practical application of this curve,and other test parameters
注意与该曲线的实际应用相关的更多详细信息以及其他测试参数
e.g.tolerances,are given in EN1363-2.
4.4 The 'semi-natural'fire
During the'semi-natural'fire test the temperature of the fire gases adjacent to the soffit of the ceiling shall reach1000℃ within 10 min to 20 min of the start of the test.
在 “半自然”防火试验中 ， 与天花板拱腹相邻的火灾气体温度应在试验开始后 10 英里至 20 分钟内达到 1000°C。
Because of the difficulties in achieving the necessary thermal attack in a conventional furnace,the attack shall be provided by fire from wooden cribs made from softwood.
由于在常规炉中难以实现必要的热攻， 因此应通过软木制成的木制熔炉的火来提供攻击。
NOTE 1 The'semi-natural'fire is a fire which produces direct flame impingement with a high convective heat transfer content which is not realized in furnace tests using the standard temperature/time curve.The term 'semi-natural'fire corresponds to the single burning item exposure required for ceilings in 4.3.1.3.4(a)of the Interpretative Document 2(not to be confused with the“single burning item”test for reaction to fire).It is relevant only for lightweight suspended horizontal protective membranes having a low thermal inertia.
注 1：“ 半自然”火是产生直接火焰撞击的火 ，具有高对流传热含量 ，这是使用标准温度/时间曲线的炉子测试中无法实现的。 术语 “半自然”火灾对应于解释性文件 4.3.1.3.4（a）中天花板所需的单个燃烧物品暴露 （不要与 “单个燃烧项目”反应测试相混淆） 火）。它仅适用于具有低热惯性的轻质悬浮水平保护膜 。

5.2 Performance characteristics
5.2.1 R-Loadbearing capacity
Loadbearing capacity R is the ability of the element of building construction to withstand fire exposure under specified mechanical actions,on one or more faces,for a period of time,without any loss of structural stability.
承载能力 R 是建筑构件在指定机械作用下承受火灾暴露的能力 ， 在一个或多个面上， 持续一段时间 ，没有任何结构稳定性的损失 。
The criteria which provide for assessment of imminent collapse will vary as a function of the type of loadbearing element.
用于评估即将倒塌的标准将根据承重元件的类型而有所不同 。
They shall be either:
它们应是 ：
a) for flexurally loaded elements,e.g.floors,roofs,a rate of deformation (rate of deflection)and a limit state for the actual deformation(deflection);

c） 对于高架地板 ， 上述标准不适用。 当试样无法再支撑施加的载荷时，即当地板或其支撑之一倒塌。
5.2.2 E-Integrity
5.2.2.1 General
Integrity E is the ability of the element of building construction that has a separating function,to withstand fire exposure on the exposed side only (not from both sides simultaneously),without the transmission of fire to the unexposed side as a result of the passage of flames or hot gases.They may cause ignition either of the unexposed surface or of any material adjacent to that surface.
完整性 E 是建筑构造中具有分离功能 ， 仅承受暴露侧 （非两侧 ）火灾暴露的能力同时 ），不会因火焰或热气体的通过而将火传送到未暴露的一侧 。 它们可能会导致未暴露的表面或与该表面相邻的任何物质的着火 。
The assessment of integrity shall generally be made on the basis of the following three aspects:
诚信的考核一般应根据以下三个方面进行：
一 cracks or openings in excess of given dimensions;
一给定尺寸的裂缝或开口 ;
一 ignition of a cotton pad(only if insulation is to be considered as well);
一点燃化妆棉 （ 仅当还考虑绝缘时 ）;
一 sustained flaming on the unexposed side.
一未暴露的一侧持续燃烧 。
The integrity shall be determined by all three methods during the test,and the cotton pad is applied for a maximum of 30 s or until it ignites if insulation is to be considered as well.Once it has ignited it is withdrawn and the test continued until all three aspects have been exceeded (the sponsor has the option,however,of stopping the test once the desired level has been reached).The times of each mode of integrity failure are recorded.
在测试过程中 ，应通过所有三种方法确定完整性 ，并且化妆棉最多使用 30 秒 ， 如果还要考虑绝缘 ，则化妆棉不会点燃 。一旦点燃 ， 它就会被撤回并继续测试 ，直到超过所有三个方面 （ 但是 ， 申办者可以选择停止达到所需水平后进行测试 ）。 记录每种完整性失败模式的时间 。
Failure of the loadbearing capacity criterion shall also be considered as failure of integrity.
承重能力标准的失败也应被视为整体性失败 。
Classification for integrity (E)shall be according to whether or not the element is also classified for insulation (I,I₁or I₂).Where an element is classified both for integrity and insulation,the value of integrity is that determined by whichever of the three aspects fails first.Where an element is classified without an insulation classification (i.e.for the classifications E,EW,RE and REW),the value of integrity is that determined by the time to failure of only the cracks/openings or sustained flaming aspects,whichever fails first.
完整性分类 （E）应根据元件是否也分类为 f 或绝缘（I，I₁或 I₂）。如果一个元件同时具有完整性和绝缘性 ，则完整性的值是由三个方面中哪个方面首先失效决定的 。如果一个元件在没有绝缘分类的情况下进行分类（ 即对于分类 E、EW、RE 和 REW）， 则完整性仅由裂纹的失效时间决定 s/开口或持续燃烧方面，以先失败者为准 。
The relevant test standards specify how the different areas of elements which have some insulated and some un-insulated parts are to be tested.
相关测试标准规定了如何测试具有某些绝缘部分和一些非绝缘部分的电气的不同区域 。

Introduction
介绍
The aim of this document is to define a harmonized procedure for the classification for fire resistance of construction products and building elements.This classification is based on the test procedures listed in Clause 2 and the relevant field of application procedures.
本文件的目的是为建筑产品和建筑构件的耐火性分类定义一个严格的程序 。该分类基于第 2 条中列出的测试程序和相关应用程序领域 。
This document is prepared in support of the second basic requirement for construction works,in the REGULATION(EU)No305/20110F THE EUROPEAN PARLIAMENTANDOF THE COUNCIL of9 March 2011 and is detailed in the Interpretative Document number 2(ID2):Safety in case of fire (OJC62 Vol 37).It reflects the Commission Decision(EU)2000/367/EC of 3 May 2000 amended by 2003/629/EC of 27 August 2003 and 2011/232/EC of 11 April 2011 as regards the classification of the resistance to fire performance of construction products,construction works and parts thereof.
本文件是为了支持 2011 年 3 月 9 日欧洲议会和理事会的法规（EU）No305/20110F 中关于建筑工程的第二个基本要求而编写的， 并在解释性解释中进行了详细说明文档 t 编号 2（ID2）： 火灾时的安全性 （OJC62 第 37 卷）。它反映了经 2003 年 8 月 27 日第 2003/629/EC 号和 2011 年 4 月 11 日第 2011/232/EC 号修订的 2000 年 5 月 3 日欧盟委员会第 2000/367/EC 号决定 ，该决定对建筑产品、建筑工程及其部件的耐火性能 。
CEN,CENELEC and EOTA committees preparing technical specifications which contain performance requirements against fire resistance tests are expected to refer to the fire resistance classification given in this document and not refer directly to any specific fire test method.
CEN、CENELEC 和 EOTA 委员会制定包含耐火测试性能要求的技术规范 ，参考本文件中给出的耐火分类 ， 而不是直接参考任何特定的防火方法。
This document has been prepared under a Standardization Request given to CEN by the European Commission and the European Free Trade Association.
本文件是根据欧盟委员会和欧洲自由贸易协会向 CEN 提出的 S 标准化请求编写的 。
This document provides for a common understanding for these requirements.It interprets the functional requirements for the different groups of building elements and explains the method for deriving their classification on the basis of test results(Direct field of application)and/or extended application results for individual elements.
本文档提供了对这些要求的共同理解 。它解释了不同建筑构件组的功能要求 ，并解释了根据测试结果（直接应用领域）和 /或扩展应用结果对单个构件进行分类的方法。
NOTE Test reports constitute the basis for extended application reports as explained in EN15725.
注意 测试报告构成扩展应用报告的基础 ， 如 EN15725 中所述 。
EN13501-2:2023(E)
2023 年 EN13501 月 2 日-2 时（日本）
Where a test specimen incorporates a closure for a conveyor system together with a penetration and its penetrating components,this shall result in an I classification allocated to the penetrating component or penetration seal.The complete closure and conveyor system assembly,however,shall be classified using the appropriate index for I₁or I₂to distinguish between the two possible ways of assessing the closure for the conveyor system.
如果试样包含输送系统的封闭件以及贯穿件及其穿透部件 ， 则应导致分配给穿透部件或贯穿件的 I 分类密封。 然而， 完整的封闭和输送系统应使用 I₁ 或 I₂ 的适当索引进行组装 ，以区分两种可能的评估方式输送系统的封闭 。
Failure of any integrity criterion shall also mean failure of thermal insulation,whether or not the specific thermal insulation temperature limits have been exceeded.
任何积分标准的失败也意味着隔热失效 ，无论是否超过特定的隔热温度限制 。
5.2.4 W-Radiation
5.2.4W 辐射
Radiation W is the ability of the element of building construction to withstand fire exposure on the exposed side only (not from both sides simultaneously),so as to reduce the probability of the transmission of fire as a result of significant radiated heat either through the element or from its unexposed surface to adjacent materials.The element may also need to protect people in the vicinity. An element which satisfies the thermal insulation criterion I,I₁or I₂is also deemed to satisfy the W requirement for the same period.
辐射 W 是建筑构件仅承受暴露侧（不能同时来自两个侧 ） 的火灾暴露的能力 ，以降低由于通过元件或从其未暴露的表面向相邻材料辐射大量热量 ， 火灾传播 。该元素可能还需要保护附近的人 。 满足隔热标准 I、I₁或 I₂ 的元件也被认为满足相同外径的 W 要求 。
Failure of integrity under the cracks or openings in excess of given dimensions or the sustained flaming at unexposed side criteria means automatically failure of the radiation criterion.
在超过给定尺寸的裂缝或开口下完整性失效 ，或在未暴露的侧面标准处持续燃烧意味着辐射标准自动失效 。
Elements for which the radiation criterion is evaluated shall be identified by the addition of a W to the classification (e.g.EW,REW).For such elements,the classification shall be given by the time for which the maximum value of radiation,measured as specified in the test standard,does not exceed a value of 15kW/m² .
评估辐射标准的元素应通过在分类中添加 faW 来识别 （ 例如电子电荷、红电工程）。对于此类元件， 分类 sh 均以测试标准中规定的辐射最大值不超过 15kW/值的时间给出平方米 。
The classification of thermal insulation shall always be given in combination with integrity,i.e.EW.
隔热材料的分类应始终与完整性相结合 ， 即 EW。

In general,the classes shall be expressed as follows:
一般而言，类别的表述如下 ：
For loadbearing elements:
对于承重元件：
REI tt: tt being the classification period during which all criteria loadbearing capacity,
REI tt：tt 为所有临界承载能力 ，
integrity and thermal insulation are satisfied;
完整性和隔热性得到满足;
RE tt: tt being the classification period during which the criteria loadbearing capacity and
RE tt：tt 是标准承载能力和
integrity are satisfied;
诚信是满意的;
R tt: tt being the classification period during which the criterion loadbearing capacity is
R tt： tt 为标准承载能力为 h 的分类周期
satisfied.
满意。
For non-loadbearing elements:
对于非承重元件：
EI tt: tt being the classification period during which the criteria integrity and thermal
EItt：tt 是完整性和热标准期间的分类期
insulation are satisfied;
绝缘满足 IED;
E tt: tt being the classification period during which the criterion integrity is satisfied.
E tt：tt 是满足标准 integrity 的分类期 。
Thus,the following example classes may be specified:
因此， 可以指定以下示例类 ：
REI 15,RE 20...
列王 15 章，启 20 章......
EI 45,E60..
不是 45，E60.。
Test results and extended application results shall always be rounded down to the nearest lower class. When characteristics are combined,the time declared shall be that for the characteristic having the shortest time.So,an element of building construction with a loadbearing capacity of 155 min,an integrity by the cotton pad of 80 min,integrity by cracks/flaming of 85 min and a thermal insulation of 42 min shall be classified REI 30/RE 60/R120.
试验结果和扩展应用结果应始终向下舍入到最接近的较低等级。 当特性组合时， 声明的时间应为具有最短时间的特性的时间 。因此，建筑构造的构件承载能力为 155min， 化妆棉完整性为 80min， 裂缝/火焰完整性为 85min， 密封性为 42 分钟的绝缘应分类为 REI30/RE60/R120。
6.4 Combinations of classes
6.4 类组合
Only those combinations of designatory letters and performance times explained in Clause 7 shall be used for the relevant elements.
只有第 7 条中解释的指定字母和执行时间的组合才应用于相关要素。
6.5 Particular classifications
6.5 特定分类
6.5.1 Doorsets,shutter assemblies and openable windows
6.5.1 门套、百叶窗组件和可开窗
In the specific case of doorsets,shutters assemblies and openable windows for the thermal insulation criterion,two different levels are specified.Hence,the classification shall be made specific by the use of one of the suffixes 1 and 2,to indicate the subclass (see 5.2.3.3).
在门套、百叶窗组件和可开窗的隔热标准的具体情况下 ， 指定了两个不同的级别 。因此， 应通过使用后缀 1 和 2 之一来具体分类，以表示子类 （ 见 5.2.3.3）。
NOTE Integrity,however,is determined in exactly the same way as for other elements.
注意完整性的确定方式与其他元素完全相同 。
Where the test results and the extended application results lead to a difference in failure time for I1 and I₂,the element may have more than one classification.For example,a doorset failing the first thermal insulation criterion after 50 min and the second criterion after 70min(failing E after95 min) shall be classified E90/EI₁45/EI₂60.
当试验结果和扩展应用结果导致 I1 和 I₂ 的失效时间存在差异时 ，元素马 y 有多个分类。 例如， 门套在 50 分钟后未通过第一个隔热标准 ， 在 70 分钟后未达到第二个标准 （在 E 后 95 分钟不合格）应被分类为 E90/EI₁45/EI₂60。
Where the difference in performance does not lead to a difference in classification,the element shall be classed with the suffix of the strictest requirement.The suffix 1 here indicates that the doorset satisfies also the second thermal insulation criterion.For example,a doorset failing the first thermal insulation criterion after 50 min and the second criterion after 55 min(failing Eafter 70 min)shall be classed E60/EI145.
性能差异不导致分类差异的， 应以最严格要求后缀对元素进行分类 。此处的后缀 1 表示门套也满足第二隔热标准。 例如， 门套在 50 分钟后未通过第一个隔热标准 ， 在 55 分钟后未达到第二个标准 （ 在 70m 英寸后未通过）应被分级为 E60/EI145.

In such cases the fire resistance classification shall be based on the fire exposure from the side demonstrated as giving the lower fire resistance time.
在这种情况下，耐火性分类应 基于从证明为较低耐火时间的侧面的火灾暴露 。
Asymmetrical fire separating elements may be tested from one side only:

a)if the weakest side can be assumed;
a）如果可以假设最弱的一方;
b)where a classification for fire attack from one side only is envisaged.

If a fire separating element is tested from the assumed weakest side only,the assumption shall be based on laboratory experience and the relevant analysis shall be fully documented in the classification report.
If an asymmetrical element is classified for one side only,the classification report shall mention this explicitly.
Beams may be tested with a three-or four-sided exposure dependent upon the envisaged application. Loadbearing walls may be tested with both sides exposed for some applications.

4.3 慢加热曲线（smouldering fire）
The smouldering fire test shall only be used if it is expected that the fire resistance performance of the element may be reduced by exposure to temperatures associated with the growth stage of a fire. It is,therefore,particularly relevant to elements whose performance may be dependent upon high heating rates below approximately 500℃(as provided during the standard temperature/time curve) for achievement of their classifications(i.e.mainly reactive or intumescent products).
仅当预计元件的耐火性能可能会因暴露于与火灾生长阶段相关的温度而降低时 ，才使用阴燃火场。 因此，它与性能可能取决于低于约 500°C 的高加热速率（如标准 温度/时间曲线中提供的）以实现其分类的元素 （即主要是反应性或膨胀性产品 ）特别相关。

5.2.2 E-Integrity
5.2.2.1 General
Integrity E is the ability of the element of building construction that has a separating function,to withstand fire exposure on the exposed side only (not from both sides simultaneously),without the transmission of fire to the unexposed side as a result of the passage of flames or hot gases.They may cause ignition either of the unexposed surface or of any material adjacent to that surface.
完整性 E 是建筑构造中具有分离功能 ， 仅承受暴露侧 （非两侧 ）火灾暴露的能力同时 ），不会因火焰或热气体的通过而将火传送到未暴露的一侧 。 它们可能会导致未暴露的表面或与该表面相邻的任何物质的着火 。
The assessment of integrity shall generally be made on the basis of the following three aspects:
诚信的考核一般应根据以下三个方面进行：
一 cracks or openings in excess of given dimensions;
一给定尺寸的裂缝或开口 ;
一 ignition of a cotton pad(only if insulation is to be considered as well);
一点燃化妆棉 （ 仅当还考虑绝缘时 ）;
一 sustained flaming on the unexposed side.
一未暴露的一侧持续燃烧 。
The integrity shall be determined by all three methods during the test,and the cotton pad is applied for a maximum of 30 s or until it ignites if insulation is to be considered as well.Once it has ignited it is withdrawn and the test continued until all three aspects have been exceeded (the sponsor has the option,however,of stopping the test once the desired level has been reached).The times of each mode of integrity failure are recorded.
在测试过程中 ，应通过所有三种方法确定完整性 ，并且化妆棉最多使用 30 秒 ， 如果还要考虑绝缘 ，则化妆棉不会点燃 。一旦点燃 ， 它就会被撤回并继续测试 ，直到超过所有三个方面 （ 但是 ， 申办者可以选择停止达到所需水平后进行测试 ）。 记录每种完整性失败模式的时间 。
Failure of the loadbearing capacity criterion shall also be considered as failure of integrity.
承重能力标准的失败也应被视为整体性失败 。
Classification for integrity (E)shall be according to whether or not the element is also classified for insulation (I,I₁or I₂).Where an element is classified both for integrity and insulation,the value of integrity is that determined by whichever of the three aspects fails first.Where an element is classified without an insulation classification (i.e.for the classifications E,EW,RE and REW),the value of integrity is that determined by the time to failure of only the cracks/openings or sustained flaming aspects,whichever fails first.
完整性分类 （E）应根据元件是否也分类为 f 或绝缘（I，I₁或 I₂）。如果一个元件同时具有完整性和绝缘性 ，则完整性的值是由三个方面中哪个方面首先失效决定的 。如果一个元件在没有绝缘分类的情况下进行分类（ 即对于分类 E、EW、RE 和 REW）， 则完整性仅由裂纹的失效时间决定 s/开口或持续燃烧方面，以先失败者为准 。
The relevant test standards specify how the different areas of elements which have some insulated and some un-insulated parts are to be tested.
相关测试标准规定了如何测试具有某些绝缘部分和一些非绝缘部分的电气的不同区域 。

All classification periods against any of the characteristics shall be declared in minutes,using one of the periods:10,15,20,30,45,60,90,120,180,240 or 360.
NOTE Not all periods apply to all elements,and further clauses show which classification periods apply to which elements.
6.2 Designatory letters
For the classification of elements of building construction use shall be made of the designatory letters shown in 5.2.
6.3 Declaration of classification
Combinations of these designatory letters,as appropriate,shall be used as part of the declaration of performance.They shall be supplemented by the time,in elapsed completed minutes of the nearest lower class during which the functional requirements are satisfied.Additionally,the load level shall be specified if appropriate.
EN13501-2:2023(E)
Classification for integrity shall be according to whether or not the element is also classified for insulation.Where an element is classified both for integrity and insulation,the value of integrity is that determined by whichever of the three aspects fails first.Where an element is classified without an insulation classification,the value of integrity is that determined by the time to failure of only the cracks/openings or sustained flaming aspects,whichever fails first.
7.3.2.3.3 Thermal insulation
The performance level used to define thermal insulation shall be the mean temperature rise on the unexposed face,limited to 140℃ above the initial temperature (as defined in EN 1363-1),with the maximum temperature rise at any point limited to 180℃ above the initial temperature (as defined in EN 1363-1).
The test standard specifies how both for uniform and non-uniform elements the mean temperature shall be determined.
7.3.2.3.4 Radiation
Classification for radiation shall be given by the time for which the maximum value of radiation, measured as specified in the test standard,does not exceed 15kW/m² .
7.3.2.3.5 Mechanical action
The element shall resist the impact as described in the test standard,without prejudice to the R,E and/or I performance.
7.3.2.4 Classes
The following classes(Table 2)are specified:
Table 2—Classes for loadbearing walls with fire separating function
RE | 20 | 30 | 45 | 60 | 90 | 120 | 180 | 240 | 360 | |
REI | 15 | 20 | 30 | 45 | 60 | 90 | 120 | 180 | 240 | 360 |
REI-M | 30 | 45 | 60 | 90 | 120 | 180 | 240 | 360 | ||
REW | 20 | 30 | 45 | 60 | 90 | 120 | 180 | 240 | 360 |
When the elements are tested from both sides,with standard temperature/time curve from inside and external fire exposure curve from outside,the lowest time determines the classification.
Test and classification may also be performed from one side only.Whichever test(s)is/are performed and classification(s)determined,the classes are identified by:
“i→o”when classification is envisaged from inside to outside;“o→i”
when classification is envisaged from outside to inside;
"o⇔i"when classification is envisaged from inside to outside and from outside to inside.
For example,a classification REI 60(i→o) indicates a wall which is capable of providing 60 min loadbearing capacity,integrity and thermal insulation performance from the inside only,whereas a classification REI 60(o→i)indicates a wall with the ability to provide the same level of performance from both inside and outside.
With external fire exposure,the classification shall be given as REI 30-ef,or REI 60-ef(o→i).
EN13501-2:2023(E)
In general,the classes shall be expressed as follows:
For loadbearing elements:
REI tt: tt being the classification period during which all criteria loadbearing capacity,
integrity and thermal insulation are satisfied;
RE tt: tt being the classification period during which the criteria loadbearing capacity and
integrity are satisfied;
R tt: tt being the classification period during which the criterion loadbearing capacity is
satisfied.
For non-loadbearing elements:
EI tt: tt being the classification period during which the criteria integrity and thermal
insulation are satisfied;
E tt: tt being the classification period during which the criterion integrity is satisfied.
Thus,the following example classes may be specified:
REI 15,RE 20...
EI 45,E60..
Test results and extended application results shall always be rounded down to the nearest lower class. When characteristics are combined,the time declared shall be that for the characteristic having the shortest time.So,an element of building construction with a loadbearing capacity of 155 min,an integrity by the cotton pad of 80 min,integrity by cracks/flaming of 85 min and a thermal insulation of 42 min shall be classified REI 30/RE 60/R120.
6.4 Combinations of classes
Only those combinations of designatory letters and performance times explained in Clause 7 shall be used for the relevant elements.
6.5 Particular classifications
6.5.1 Doorsets,shutter assemblies and openable windows
In the specific case of doorsets,shutters assemblies and openable windows for the thermal insulation criterion,two different levels are specified.Hence,the classification shall be made specific by the use of one of the suffixes 1 and 2,to indicate the subclass (see 5.2.3.3).
NOTE Integrity,however,is determined in exactly the same way as for other elements.
Where the test results and the extended application results lead to a difference in failure time for I1 and I₂,the element may have more than one classification.For example,a doorset failing the first thermal insulation criterion after 50 min and the second criterion after 70min(failing E after95 min) shall be classified E90/EI₁45/EI₂60.
Where the difference in performance does not lead to a difference in classification,the element shall be classed with the suffix of the strictest requirement.The suffix 1 here indicates that the doorset satisfies also the second thermal insulation criterion.For example,a doorset failing the first thermal insulation criterion after 50 min and the second criterion after 55 min(failing Eafter 70 min)shall be classed E60/EI145.
See 7.5.5 for the full classification.
EN13501-2:2023(E)

一 guidance on test specimen design.
Aspects influencing the number of tests to be carried out shall include for example:
a) the range of loading conditions to be covered;

6.5.2 Conveyor systems and their closures
In the specific case of closures and conveyor system assemblies,for the thermal insulation criterion, three different levels are specified (see 5.2.3.4).Hence,the classification shall be made specific by the use of one of the suffixes 1 and 2,if applicable,to indicate any subclass.
As an example,the complete closure and conveyor system assembly may have any one or more of the following classifications for different test specimens:E120,EI 90,EI145,EI₂60.
The principles of integrity classification given in 6.5.1 shall also apply to closures and conveyor system assemblies.
6.6 Additional performance parameters
6.6.1 Optional performance parameters
Where required,the classification shall include the following optional performance parameter:
W when radiation has been measured and for the period the criterion of 15 kW/m²has been satisfied,the W criterion intervenes in the same way as the R,E and I criteria, e.g.REW 30,EW 30.
6.6.2 Expansion of performance parameters
The classification may be expanded by the use of any of the following performance parameters,when applicable:
M when particular mechanical actions are considered and the element satisfies the criteria of 5.2.5,e.g.REI 30-M;
S for elements with particular limitations on smoke leakage;
For fire resistant elements theS shall be added to the fire resistance classification(e.g.
EI260-S₂00).Where no fire resistance classification is relevant,the element shall simply be classified S.The S classification shall be determined under ambient Sa and/or medium temperature conditions S200 as a function of the classification envisaged;
C for doorsets and shutters and closures for conveyor systems equipped with a self- closing device,e.g.EI230-C3.Where no fire resistance or smoke control classification is relevant,the element shall simply be classified C(C0 to C5);

requirement to the standard temperature/time exposure (only relevant for lightweight horizontal protective membranes having a low thermal inertia and not mandatory for all horizontal protective membranes),the classification of the element protected by that protective membrane shall be so identified,e.g.R60-sn;
ef where performance against the external fire exposure curve instead of the standard temperature/time exposure is determined,the classification of the element shall be so identified,e.g.EI 60-ef;
r where performance against the constant temperature attack of 500℃(reduced
temperature exposure]instead of the standard temperature/time exposure is determined,the classification of the element shall be so identified,e.g.RE 30-r.
EN13501-2:2023(E)
7.3.3.3.2 Integrity
The assessment of integrity shall be made on the basis of the following three aspects:
a)cracks or opening in excess of given dimensions;
b) ignition of a cotton pad (only if insulation is to be considered as well);
c) sustained flaming on the unexposed side.
Classification for integrity shall be according to whether or not the element is also classified for insulation.Where an element is classified both for integrity and insulation,the value of integrity is that determined by whichever of the three aspects fails first.Where an element is classified without an insulation classification,the value of integrity is that determined by the time to failure of only the cracks/openings or sustained flaming aspects,whichever fails first.

7 Classification procedure for fire resistance
7.1 General
7.1.1 Procedure
a) The envisaged field of application of the classification shall be proposed by the sponsor and includes aspects such as:
EN13501-2:2023(E)
Aspects influencing the number of tests to be carried out shall include for example:
a) the range of exposure conditions to be covered(standard exposure and/or reduced exposure);
b)the range of loading conditions to be covered;
c) constructional variations required.
7.3.4.3 Performance criteria
7.3.4.3.1 Loadbearing capacity
Failure shall be deemed to have occurred when the floor itself or one of the supporting studs has collapsed.
7.3.4.3.2 Integrity
The assessment of integrity shall be made on the basis of the following three aspects:
a) cracks or opening in excess of given dimensions;
b)ignition of a cotton pad (only if insulation is to be considered as well);
c) sustained flaming on the non-exposed side.
Classification of integrity shall be according to whether or not the element is also classified for thermal insulation.Where an element is classified both for integrity E and thermal insulation I,the integrity value shall be that determined by whichever of the three criteria fails first.Where an element is classified E but without an I classification,the integrity value shall be defined as the time to failure of only the cracks/openings or sustained flaming criteria,whichever fails first.
7.3.4.3.3 Thermal Insulation
The performance level used to define thermal insulation shall be the mean temperature rise on the unexposed face,limited to 140 ℃ above the initial mean temperature,with the maximum temperature rise at any point limited to 180℃ above the initial mean temperature.
7.3.4.4 Classes
The following classes(Table 4)are specified:
Table 4-Classes for raised floors
RE | 10 | 15 | 20 | 30 | 60 | 90 | 120 | 180 | 240 | 360 |
REI | 10 | 15 | 20 | 30 | 60 | 90 | 120 | 180 | 240 | 360 |
The classification shall be made specific depending on the exposure.
The absence of the designation letter r refers to standard temperature/time curve exposure(full fire resistance]whereas its presence refers to the constant temperature attack of 500℃〔reduced exposure),e.g.RE 30,and RE 30-r.
Raised floors satisfying the standard temperature/time curve exposure for a given time are considered to satisfy the reduced exposure conditions for at least the same period.
EN13501-2:2023(E)
一 exposure conditions:for asymmetrical elements,the side(s)to be exposed,one/two sides exposure for walls,three/four sides exposure for beams etc.;
一 dimensions of the element:including span,height,width;
—boundary and support conditions:restrained or unrestrained,deflection and/or rotation load level (see 3.26);
一 variation of constructional details;
一 the envisaged class(es):i.e.combinations of performance criteria and time(s).
b) Taking into account the direct field of application of test results as specified in the relevant test method and/or the extended application results,the number of tests,standard temperature/time tests and other exposures,and the specimen to be tested shall be deduced.
c) As a function of the components involved in the element of building construction,and the type of element,the need for tests under other than the standard temperature/time curve shall be verified:
一 the slow heating curve for elements whose performance may be dependent upon high heating rates below 500℃,for achievement of their classification;
一 the'semi-natural'fire for lightweight suspended horizontal protective membranes;
一 the external fire exposure curve for external faces of non-loadbearing walls;
一 constant temperature attack for e.g.smoke control doorsests,raised floors,chimneys.
d) The standard temperature/time fire tests shall be carried out and for each test the times shall be determined,in elapsed minutes,for which the test specimen continues to satisfy the different aspects of the performance criteria:
R-Loadbearing capacity —limiting deformation;
—limiting rate of deformation;
E-Integrity —ignition of cotton pad (only if insulation is to be considered as well);
—cracks and openings;
—occurrence of sustained flaming on the unexposed side;
I-Thermal insulation —mean temperature rise;
—maximum temperature rise;
W-Radiation —maximum radiation level.
For particular elements other aspects are measured or verified:
S-Smoke leakage —limiting leakage rate;
M-Mechanical action —resistance to impact;
C-Self-closing —self-closure in the event of fire;
EN13501-2:2023(E)
7.4 Products and systems for protecting elements or parts of works
7.4.1 General
This category of products and systems includes ceilings (horizontal protective membranes),vertical screens or partitions (vertical protective membranes)and fire protective coatings,boards,renderings and claddings.
These products and systems do not necessarily claim nor possess fire resistance on their own.They are intended to increase (or to provide)fire resistance of the structural members they protect.
The test methods characterize the products and systems for protecting elements or parts of works in such a way that the field of application of test results can be extended to other structural members than those included in the standard test(s).
Classification applies to the protected element,including its protection,and not to the protection itself.Classification of protective elements can be reached using the characterization data as collected from the tests,together with relevant calculation methods,e.g.from published European design code (e.g.EN1993-1-2 or EN 1994-1-2)but that is outside the scope of this document.
7.4.2 Tests to be carried out
The test(s)to be carried out,the allowed extension of the field of application of the test results and the procedure(s)to be followed for that purpose depends upon:
一 the nature of the protective product:
a) horizontal membranes(ceilings);
b)vertical membranes (screens);
c) fire protective coatings,boards,renderings and claddings;
一 the nature of the structural elements to be protected:
a) steel;
b) concrete;
c) composite steel/concrete;
d)timber;
e) aluminium.
The design of the test specimen and the number of tests to be carried out shall be derived from a comparison between the envisaged field of application of the classification for different families of structural members and the field of application of test results as specified in the test standard.
The test methods provide information on the following:
— test specimen;
一 field of direct application of test results;
一 guidance on test specimen design,including standard configuration for the element(s)to be protected.
EN13501-2:2023(E)
0-Non-soot fire resistance —resisting the thermal attack of normal operating
conditions,for chimney related products(such as flue blocks, chimneys,connecting flue pipes);
G-Soot fire resistance —resisting the thermal attack of a soot fire,for chimney
related products;(such as flue blocks,chimneys,connecting flue pipes);
K-Fire protection ability —fire protecting ability of a covering fora specified period of time.
e) For any of the tests and criteria R,E,I,W and K,the obtained times in minutes shall be rounded down to the nearest lower value included in the following series:10,15,20,30,45,60,90,120, 180,240,360.
f) If more than one test has to be carried out because of the envisaged field of application,the lowest result shall determine the classification for the entire field of application.As the classification is linked to the field of application,results of individual tests may lead to higher ranking for a more limited field of application.
g) Classification reports shall be prepared as shown in Annex A.A classification report can be issued for any one combination of performance parameters and times that are covered by results of tests and/or by extended application results.
7.1.2 General rules for deducing the number of standard temperature/time fire resistance tests
7.1.2.1 General principles
No tests shall be duplicated for aspects of repeatability and a single test normally allows the classification of all elements identical to the tested element and those included in the field of direct application.
Asymmetrical fire-separating elements may have a different performance depending on the side from which they are tested.A test shall therefore be carried out on each side unless the conditions in 7.1.2.2 apply.
Elements have a different performance depending on load-level and boundary conditions.The field of application of the classification is determined by the load level and boundary conditions applied in the test.Additional tests may be required in function of the envisaged field of application.
The number of tests required may further depend on:
a) the combination of performance criteria envisaged;
b)the need to apply other thermal attack conditions in addition to the standard temperature/time curve.
Elements are supplied in a wide variety of sizes,shapes and materials,including finishes,to satisfy the requirements of the market.It is impractical to test every variation of shape,size or material for each element.
The extent to which a tested element may or may not be changed under the field of direct application is given in rules or guidelines in the relevant test standards,which limit the permitted variation away from the test specimen without further evaluation or calculation.
EN13501-2:2023(E)
Aspects influencing the number of tests to be carried out are,amongst others:
a) the nature of the element(s)to be protected:e.g.timber floor,concrete floor,steel structure;
b)the nature of the protection:e.g.horizontal membrane,coating.
The thermal attack is the standard temperature/time curve.
For reactive or intumescent products additional test(s)against the slow heating curve (see 4.3)may be required.
7.4.3 Test methods
The applicable test methods are EN13381-1,EN 13381-2,EN 13381-3,EN 13381-4,EN13381-5, EN 13381-6,EN 13381-8 and EN 13381-7.
7.4.4 Performance criteria
The criteria for the protected structural members are equivalent to those for the element if tested directly.
The test methods also provide data allowing the extension of the field of application of the test results both for a range of variations of the protection and the protected structural elements.Additionally, the test methods provide data on the protective ability of the product or system(s)in a form appropriate for direct input to structural design codes.
7.4.5 Classes
Coatings,boards,renderings and claddings do not possess fire resistance independently of the structural member they protect.For that reason,classification is done for the protected element or is related to that element.
Ceiling partitions used as horizontal or vertical protective membranes may or may not have fire resistance in their own right.However,when used as protective membranes classification is done for the protected element or is related to that element.
The same classes are specified as for the structural member to be protected.
7.4.6 Classification of protected structural members
7.4.6.1 General
If a classification of a protected structural member is required,this shall be carried out in accordance with the prescription of this document.
The same classes exist for the protected element as for the unprotected element.Characterization data may be included in the classification report;an illustration of such data is given in Annex B.These characterization data are made available for their use within the Eurocode-Basis of structural design.
Although products,membranes and systems for protecting elements envisage primarily the R criterion,also the EandIcriteria can be deduced as far as allowed forand according to the description in the test standards.R,E and I performance can also be demonstrated in accordance with published Eurocode -Basis of structural design (e.g.EN 1992-1-2,EN 1993-1-2,EN 1994-1-2,EN 1995-1-2, EN 1996-1-2 and EN 1999-1-2)but that is outside the scope of this document
EN13501-2:2023(E)
The extent to which a tested element may be changed under the field of extended application is given in rules or in the relevant extended application standards.
7.1.2.2 Exposure conditions
For separating elements that are required to be fire resisting from both sides,two specimens shall be tested (one for each direction)unless the separating element is fully symmetrical.
In such cases the fire resistance classification shall be based on the fire exposure from the side demonstrated as giving the lower fire resistance time.
Asymmetrical fire separating elements may be tested from one side only:
a)if the weakest side can be assumed;
b)where a classification for fire attack from one side only is envisaged.
If a fire separating element is tested from the assumed weakest side only,the assumption shall be based on laboratory experience and the relevant analysis shall be fully documented in the classification report.
If an asymmetrical element is classified for one side only,the classification report shall mention this explicitly.
Beams may be tested with a three-or four-sided exposure dependent upon the envisaged application. Loadbearing walls may be tested with both sides exposed for some applications.
7.1.2.3 Dimensions
The test specimen shall normally be full size.When the specimen cannot be tested full size,the specimen size shall be in accordance with the specification of the relevant test method.In general, test results obtained for a given span,height or width shall also be valid for a smaller span,height or width.For applicability to larger dimensions the relevant test methods or the standards on extended application shall be consulted.
7.1.2.4 Boundary and support conditions
When considering the field of application,tests with different boundary conditions may be necessary unless the most severe condition is known.
NOTE The ultimate load depends to a great extent on the boundary and support conditions.
7.1.2.5 Load level
Usually the field of application can be extended to lower load levels.
NOTE Load levels (see 3.26)are best expressed in percentage of ultimate loadbearing capacity at ambient temperature.If the ultimate loadbearing capacity at ambient temperature is notknown,the classification report will mention the actual test load and the relevant mechanical material properties of the materials used.
7.1.2.6 Variation of constructional details
In general,the field of application of a test result is limited to elements with identical constructional details.
Different variations of constructional details shall not be included in a single test specimen,unless it can be shown that they will not interfere with the performance of each other.
EN13501-2:2023(E)
7.4.6.2 Structural members protected by horizontal membranes

Limiting temperatures for specific types of materials of construction,from which loadbearing capacity is obtained,are specified for the characteristic cavity temperature as well as the characteristic surface temperature.
Fire protection products are characterized by test results expressed in terms of the time at which the limiting temperatures are reached.From this information classification of protected structural elements is obtained according to procedures detailed in the test standard.
Protected products successfully submitted to the mechanical impact test are identified by the addition of'M’,e.g.R 30-M.
7.4.6.4 Concrete members protected by coatings,boards,renderings or claddings

The test methods characterize the products and systems for protecting elements or parts of works in such a way that the field of application of test results can be extended to other structural members than those included in the standard test(s).
Classification applies to the protected element,including its protection,and not to the protection itself.Classification of protective elements can be reached using the characterization data as collected from the tests,together with relevant calculation methods,e.g.from published European design code (e.g.EN1993-1-2 or EN 1994-1-2)but that is outside the scope of this document.
7.4.2 Tests to be carried out
The test(s)to be carried out,the allowed extension of the field of application of the test results and the procedure(s)to be followed for that purpose depends upon:

c) fire protective coatings,boards,renderings and claddings;
一 the nature of the structural elements to be protected:
a) steel;
b) concrete;
c) composite steel/concrete;
d)timber;
