BS EN ISO 6974-3:2018描述了根据ISO 6974-1建立的气相色谱法的预期精度。当ISO 6974-1中描述的方法应用于一个或多个合格实验室时,所述精度提供了试验结果之间预期的可变性大小值。本文件还提供了偏见评估指南。交叉引用:ISO/IEC 17025ISO/IEC 17043:2010ISO 5725-1:1994JCGM 200:2012ISO 5725-2ASTM 6299-16ISO 6974-1购买本文件时提供的所有现行修订版均包含在购买本文件中。
BS EN ISO 6974-3:2018 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.Cross References:ISO/IEC 17025ISO/IEC 17043:2010ISO 5725-1:1994JCGM 200:2012ISO 5725-2ASTM 6299-16ISO 6974-1All current amendments available at time of purchase are included with the purchase of this document.
