标准摘要
[中文适用范围]: 本文件规定了制备需氧初始悬浮液和稀释液的一般规则,适用于微生物学检验的人类或动物食用产品。该文件也适用于其他特定部分,具体适用的产品可在前言中找到。某些方面也可能适用于分子方法,其中基质可能与PCR步骤的抑制有关,并进而影响测试结果。本文件不包括制备用于计数和检测测试方法的样品,其中详细准备说明可在相关国际标准中找到。 [外文原描述]: ISO 6887-1:2017 defines general rules for the aerobic preparation of the initial suspension and of dilutions for microbiological examinations of products intended for human or animal consumption. ISO 6887-1:2017 is applicable to the general case and other parts apply to specific groups of products as mentioned in the foreword. Some aspects might also be applicable to molecular methods where matrices can be associated with inhibition of the PCR steps and consequently affect the test result. ISO 6887-1:2017 excludes preparation of samples for both enumeration and detection test methods where preparation instructions are detailed in specific International Standards.
