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.
