EMUE-D2-3-TSPConcentration

Conformity assessment of mass concentration of total suspended particulate matter in air

The example shows how to calculate risks of false decisions in the conformity assessment of test results, according to the framework of JCGM 106:2008, in the case in which a normal distribution is not a valid assumption for modelling prior information on the measurand. As a case study, test results of mass concentration of Total Suspended Particulate Matter (TSPM) in ambient air, collected in the proximity of three stone quarries located in Israel, are considered; for each quarry, a log-normal distribution is chosen as the prior distribution.

空气中总悬浮颗粒物质量浓度的符合性评定

本示例依据JCGM 106:2008的评定框架，针对无法采用正态分布对被测量的先验信息进行建模的场景，演示了如何计算符合性评定测试结果中的误判风险。作为案例研究，本次分析采用以色列三处采石场周边采集的环境空气总悬浮颗粒物（Total Suspended Particulate Matter, TSPM）质量浓度测试数据；针对每个采石场，均选用对数正态分布作为其先验分布。[活动A1.2.3]。
