目的是通过给出计算重复性限值、再现性限值和其他限值的标准方法，提供检查在重复性或再现性条件下获得的试验结果可接受性的方法，给出在各种实际情况下使用精度数据的一些指示，描述如何评估实验室内一段时间内结果的稳定性，描述如何评估给定实验室是否能够以令人满意的方式使用给定的标准测量方法，描述如何比较替代测量方法。

The purpose is to give some indications of the way in which accuracy data can be used in various practical situations by: giving a standard method of calculating the repeatability limit, the reproducibility limit and other limits, providing a way of checking the acceptability of test results obtained under repeatability or reproducibility conditions, describing how to assess the stability of results within a laboratory over a period of time, describing how to assess whether a given laboratory is able to use a given standard measurement method in a satisfactory way, describing how to compare alternative measurement methods.
