标准范围

ISO 4259:2006涵盖了精度估算的计算及其在规范中的应用。特别是，它包含了相关统计术语的定义、实验室间试验计划规划中采用的程序，以确定试验方法的精度、根据该计划的结果计算精度的方法，以及与试验方法精度和规范中规定的限值相关的实验室结果解释中应遵循的程序。ISO 4259:2006中的程序是专门为石油和石油产品设计的-相关产品，通常是同质的。然而，本国际标准中描述的程序也适用于其他类型的均质产品。在将ISO 4259:2006应用于同质性假设可能受到质疑的产品之前，有必要进行仔细调查。

ISO 4259:2006 covers the calculation of precision estimates and their application to specifications. In particular, it contains definitions of relevant statistical terms, the procedures to be adopted in the planning of an inter-laboratory test programme to determine the precision of a test method, the method of calculating the precision from the results of such a programme, and the procedure to be followed in the interpretation of laboratory results in relation both to precision of the test methods and to the limits laid down in specifications.The procedures in ISO 4259:2006 have been designed specifically for petroleum and petroleum-related products, which are normally homogeneous. However, the procedures described in this International Standard can also be applied to other types of homogeneous products. Careful investigations are necessary before applying ISO 4259:2006 to products for which the assumption of homogeneity can be questioned.
