标准摘要
[中文适用范围]： 本文件规定了设计、规划和执行实验室间研究（ILS）以及计算研究所指定试验方法的精密度估计值的方法。具体包括：——定义了相关统计术语；——规定了规划和执行ILS以确定试验方法精密度的程序；——规定了根据此类研究结果计算精密度的计算方法。本文件中的程序专门针对石油及石油相关产品设计，这些产品通常被认为是均质的。然而，本文件所述程序也可应用于其他类型的均质产品。 [外文原描述]： This document specifies the methodology for the design, planning, and execution of an interlaboratory study (ILS) and calculation of precision estimates of a test method specified by the study. In particular: it defines the relevant statistical terms, it specifies the procedures to be adopted in the planning and execution of an ILS to determine the precision of a test method, and it specifies the method of calculating the precision from the results of such a study. The procedures in this document have been designed specifically for petroleum and petroleum related products, which are normally considered as homogeneous. However, the procedures described in this document can also be applied to other types of homogeneous products.
