ISO 25337:2010描述了一种统计模型，即所谓的单次测量，用于在生产商的生产现场使用单次测量进行生产质量控制，即使标准试验方法规定了重复测量。统计模型也适用于需要重复操作的测试方法。本文还描述了产生数值结果的试验方法标准中精度说明的一般方法。统计模型仅适用于给出服从正态（即高斯）分布结果的测试方法。 统计模型的原理基于生产上限和下限的确定，并考虑到试验方法的准确性和再现性，后者被添加到生产极限中，以定义生产极限以外的区域，其中由于生产过程和/或试验方法的性质，试验结果可能会下降。 ISO 25337是为项目经理、实验室负责人和生产经理设计的。然而，为了提供必要的技术支持和统计分析，强烈建议统计人员提供支持，有时是必不可少的。

ISO 25337:2010 describes a statistical, so-called single-measurement, model for using single measurements for production quality control purposes at a producer's manufacturing site, even if a standard test method specifies replicate measurements. The statistical model is also applicable to test methods which call for repeated operations. A general approach to the precision statement in test method standards which produce numerical results is also described. The statistical model is only applicable to test methods which give results that follow a normal (i.e. Gaussian) distribution. The principle of the statistical model is based on the determination of upper and lower production limits, taking into account the accuracy and the reproducibility of the test method, the latter being added to the production limits in order to define an area outside the production limits in which a test result can fall owing to the nature of the production process and/or the test method. ISO 25337 is designed for project managers, heads of laboratories and production managers. However, the support of a statistician is highly recommended, and sometimes indispensable, for providing the necessary technical backup and statistical analysis.
