标准范围

ISO/TR 24430:2003的目的是:就如何将精密度声明引入国际标准提出建议，该标准规定了油漆、清漆、相关材料和由其衍生的涂料的测试方法；概述评估精确度时应用的一般原则，以便建立能够进行定量估计的程序；概述进行实验室间试验的一般原则。它可以应用于油漆、清漆和相关产品、它们的固体、液体或粉末形式的原材料以及由它们衍生的涂料。它只涉及在连续尺度上操作以产生单个数字作为测试结果的测试方法。然而，这个单个数字可能是根据一组测量计算的结果。测试结果的分布要求是单峰的，并假设是正态的。对于非高斯分布，其他评估程序将是必要的。它不包括产生离散值的方法，如通过-不通过测试或排名方案正在运行的方法。

The purpose of ISO/TR 24430:2003 is:

• to give recommendations on how to introduce precision statements into an International Standard which specifies a test method for paints, varnishes, related materials and coatings derived from them;
• to outline the general principles to be applied when assessing precision in order to establish the procedures which will enable a quantitative estimate to be made;
• to outline the general principles under which interlaboratory trials should be conducted.

It may be applied to paints, varnishes and related products, to their raw materials in solid, liquid or powder form and to coatings derived from them.It is concerned only with test methods which operate on a continuous scale to yield a single numerical figure as the test result. However, this single figure may be the outcome of a calculation from a set of measurements. The distribution of test results is required to be unimodal and is assumed to be normal. With non-Gaussian distributions other evaluation procedures will be necessary. It does not cover methods which yield discrete values such as go no-go tests or where a ranking scheme is in operation.
