标准范围

ISO 17994:2004定义了一种评估程序,用于比较用于检测或量化同一目标群体或微生物物种的两种方法。ISO 17994:2004为根据选定的等效标准评估两种方法的平均相对性能提供了数学基础。可以比较基于计数(菌落或阳性管)的任何两种计数方法或用于相同目的的任何两种检测方法(存在/不存在方法)。ISO 17994:2004没有提供直接比较定量方法(菌落计数或MPN)和检测方法(P/a)的解决方案。

ISO 17994:2004 defines an evaluation procedure for comparing two methods intended for the detection or quantification of the same target group or species of microorganisms.ISO 17994:2004 provides the mathematical basis for the evaluation of the average relative performance of two methods against chosen criteria of equivalence.Any two enumeration methods based on counts (of colonies or positive tubes) or any two detection methods (presence/absence methods) intended for the same purpose can be compared.ISO 17994:2004 provides no solution to directly compare a quantitative method (colony count or MPN) with a detection method (P/A).
