标准摘要
[中文适用范围]： 本国际标准规定了根据 ISO/TR 13843 比较两种具有既定性能特征的方法的评估程序，旨在对相同目标组或微生物物种进行定量。 本国际标准为根据选定的比较标准评估两种定量方法的平均相对性能提供了数学基础。 它不提供用于评估所比较方法的精度的数据。 将方法的精度作为其性能表征的一部分进行评估是适当的。 本国际标准不提供在单个实验室中验证方法性能表征的方法。 [外文原描述]： ISO 17994:2014 specifies an evaluation procedure for comparing two methods with established performance characteristics according to ISO/TR 13843 and intended for the quantification of the same target group or species of microorganisms. It provides the mathematical basis for the evaluation of the average relative performance of two quantitative methods against chosen criteria for the comparison. It does not provide data for assessment of the precision of the methods being compared. It is appropriate that the precision of methods is assessed as part of their performance characterization. ISO 17994:2014 does not provide methods for the verification of method performance characterization in a single laboratory.
英文名称Water quality — Requirements for the comparison of the relative recovery of microorganisms by two quantitative methods
