标准摘要
[中文适用范围]： 本文件描述了根据 ISO 6974-1 建立的气相色谱方法的预期精度。 所述精度提供了当在一个或多个有能力的实验室应用 ISO 6974-1 中描述的方法时测试结果之间可以预期的变异程度的值。 本文件还提供了有关偏见评估的指导。 [外文原描述]： This document describes the precision that can be expected from the gas chromatographic method that is set up in accordance with ISO 6974-1. The stated precision provides values for the magnitude of variability that can be expected between test results when the method described in ISO 6974-1 is applied in one or more competent laboratories. This document also gives guidance on the assessment of bias.
