标准范围

本国际标准规定了化学和化学物质测量不确定度的评定方法基于验证数据和分析质量控制结果的单实验室物理化学方法在水分析领域内获得。注1:本国际标准中规定的不确定度估算原则与ISO/IEC指南98-3中描述的原则。在本国际标准中，测量不确定度的量化取决于性能通过验证获得的测量程序的特征以及内部和外部测试的结果质量控制注2:本国际标准中规定的方法主要基于QUAM[11]、NEN 7779[8]和NordtestTR 537[10]和欧洲实验室TR 1[9]。注3:本国际标准仅针对所获得结果的测量不确定度评估从定量测量程序。与定性程序所得结果相关的不确定性不被考虑。

This International Standard specifies methods for the estimation of measurement uncertainty of chemical andphysicochemical methods in single laboratories based on validation data and analytical quality control resultsobtained within the field of water analysis.NOTE 1 The principles of the estimation of uncertainty specified in this International Standard are consistent with theprinciples described in ISO/IEC Guide 98-3.In this International Standard, the quantification of measurement uncertainty relies on performancecharacteristics of a measurement procedure obtained from validation and the results of internal and externalquality control.NOTE 2 The approaches specified in this International Standard are mainly based on QUAM[11], NEN 7779[8], NordtestTR 537[10], and Eurolab TR 1[9].NOTE 3 This International Standard only addresses the evaluation of measurement uncertainty for results obtainedfrom quantitative measurement procedures. The uncertainties associated with results obtained from qualitative proceduresare not considered.
