ISO/TC 146/SC 2/WG 10 - Terminology and Quality Control in Workplace Air

This document specifies requirements for the evaluation of measuring procedures using samplers for the determination of a chemical agent present in the workplace atmosphere as a mixture of airborne particles and vapour. The procedures given in this document provide results only for the sum of airborne particles and vapour. The concentration is calculated in terms of mass per unit volume. NOTE The physical behaviour of a mixture of airborne particles and vapour is described in Annex A. Examples of substances which can be present in multiple phases are toluene diisocyanate, diethanolamine, ethyleneglycol and tributylphosphate. This document can also be applied to complex mixtures, such as metal working fluids or bitumen fumes. This document is applicable to samplers and measuring procedures using these samplers in which sampling and analysis are carried out in separate stages.

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.

This document specifies performance requirements and test methods under prescribed laboratory conditions for the evaluation of pumped samplers used in conjunction with an air sampling pump and of procedures using these samplers for the determination of gases and vapours in workplace atmospheres. This document addresses requirements for method developers and/or manufacturers. NOTE 1 For the purposes of this document, a manufacturer can be any commercial or non-commercial entity. NOTE 2 For the sampling of semi-volatile compounds which can appear as a mixture of vapours and airborne particles in workplace atmospheres see EN 13936. This document is applicable to pumped samplers and measuring procedures using these samplers in which sampling and analysis are carried out in separate stages. This document is not applicable to: — pumped samplers which are used for the direct determination of concentrations, for example, length-of-stain detector tubes; — samplers which rely on sorption into a liquid, and subsequent analysis of the solution (bubblers).
