ISO 6887-1:2017规定了用于人类或动物消费的产品的初步悬浮液的有氧制备和用于微生物检查的稀释液的一般规则。
ISO 6887-1:2017适用于一般情况,其他部分适用于前言所述的特定产品组。一些方面也可能适用于分子方法,其中基质可与PCR步骤的抑制相关联,并因此影响测试结果。
ISO 6887-1:2017不包括在具体国际标准中详细说明准备说明的计数和检测测试方法的样品制备
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.
