水质. 定量微生物法性能特征的建立要求

[中文适用范围]： 本文件涉及微生物方法的表征。 就本文件而言，表征意味着对可测量的参数的研究，以描述该方法在一组给定条件下可能如何执行，这可以被描述为性能特征。 该文件描述了确定性能特征的程序，可用于后续方法的验证或验证。 重点是选择性定量方法，本文件适用于所有类型的水。 对于不基于直接显微镜计数、菌落计数或最可能数的方法，应仔细考虑本文件中描述的程序的适用性。 [外文原描述]： ISO 13843:2017 deals with characterization of microbiological methods. In terms of ISO 13843:2017, characterization means the study of parameters that can be measured to describe how the method is likely to perform in a given set of conditions, which can be described as performance characteristics. ISO 13843:2017 describes procedures for the determination of performance characteristics which can be used for subsequent validation or verification of methods. The emphasis is on selective quantitative methods and ISO 13843:2017 applies to all types of water. For methods that are not based upon direct microscopic count, colony count or most probable number, the applicability of the procedures described in ISO 13843:2017 should be considered carefully.
