ISO 6887-1:2017定义了用于人类或动物食用产品微生物检查的初始悬浮液和稀释液的需氧制备的一般规则。 ISO 6887-1:2017适用于一般情况，其他部分适用于前言中提到的特定产品组。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，从而影响检测结果。 ISO 6887-1:2017不包括计数和检测试验方法的样品制备，其中制备说明在具体国际标准中有详细说明。

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.
