Conditions for storage after receipt of the sample may differ from the conditions under which the PT sample was transported 收到样品后的储存条件可能与 PT 样品的运输条件不同
Stability data have shown that uncooled transport of samples intended to be stored at 2-8^(@)C2-8^{\circ} \mathrm{C} does not affect the stability of the test materials for the time of the PT round 稳定性数据表明，打算储存的 2-8^(@)C2-8^{\circ} \mathrm{C} 样品的未冷却运输不会影响测试材料在 PT 轮次期间的稳定性
The test material(s) should be analysed in accordance with the deadlines shown on the website: https://portal.lgcstandards.com 应根据网站上显示的截止日期对测试材料进行分析：https://portal.lgcstandards.com
Choice of method or procedure 方法或程序的选择
Participants are expected to use the test method, calibration, or measurement procedure of their choice. This method should be consistent with the participant’s normal procedures, for example, duplicate analysis should only be performed if that is part of the routine analytical process. Some samples may require specific preparation or analysis, if so, this is indicated in this document. 参与者应使用他们选择的测试方法、校准或测量程序。该方法应与参与者的正常程序一致，例如，只有当重复分析是常规分析过程的一部分时，才应进行重复分析。某些样品可能需要特定的制备或分析，如果是这样，则在本文件中进行了说明。
Participants may submit results for some, or all the parameters requested. 参与者可以提交所要求的部分或全部参数的结果。
Sample Details (Chemistry) 样品详情（化学成分）
Chemistry test materials are presented in a ready-to-use format. 化学测试材料以即用型形式提供。
Sample Details (Microbiology) 样品详情（微生物学）
The test materials represent ‘real’ food or beverage samples, which may or may not contain the target organism(s) at a range of inoculum levels. Test materials may also contain background flora. 测试材料代表“真实”食品或饮料样品，其中可能含有也可能不包含一定接种水平的目标生物体。测试材料也可能包含背景菌群。
Please consider all dilution factors when calculating the level of the target organisms in the original sample. Where relevant guidance is given in the instructions. 在计算原始样品中目标生物体的水平时，请考虑所有稀释因子。在说明中给出相关指导的情况下。
Do not sub-divide samples prior to dilution unless stated in the instructions. 除非说明中另有说明，否则不要在稀释前对样品进行细分。
