ISO 23320:2022 PDF

Scope: This document specifies performance requirements and test methods under prescribed laboratory conditions for the evaluation of diffusive samplers (see Reference [1]) and of procedures using these samplers for the determination of gases and vapours in workplace atmospheres (see Reference [2]). This document is applicable to diffusive samplers and measuring procedures using these samplers, such as ISO 16200-2 and ISO 16017-2, in which sampling and analysis are carried out in separate stages. This document is not applicable to — diffusive samplers which are used for the direct determination of concentrations, and — diffusive samplers which rely on sorption into a liquid. This document addresses requirements for method developers and/or manufacturers. NOTE For the purposes of this document a manufacturer can be any commercial or non-commercial entity.
