Workplace atmospheres. Controlling and characterizing uncertainty in weighing collected aerosols Ingestion-build-79769 With this method1 Scope This International Standard provides recommendations for controlling the analytical uncertainty associated with aerosol collection medium instability, where collection medium or collection substrate includes any article used to collect particles (e. g. filter or foam material) as well as those supporting elements which must be analysed by weighing. This International Standard is applicable to results compiled both from the literature and, if
