Workplace air - Gases and vapours - Requirements for evaluation of measuring procedures using diffusive samplers

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.

ZOOM ON ... the Requirements department
To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.

The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.
