Workplace air - Gases and vapours - Requirements for evaluation of measuring procedures using diffusive samplers (ISO 23320:2022)

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.

Le présent document s’applique aux dispositifs de prélèvement par diffusion et aux procédures de mesurage utilisant ces dispositifs, telles que celles de l’ISO 16200-2 et l’ISO 16017-2, pour lesquels le prélèvement et l’analyse sont effectués dans des étapes séparées.
Le présent document ne s’applique pas:
—    aux dispositifs de prélèvement par diffusion utilisés pour la détermination directe des concentrations; et
—    aux dispositifs de prélèvement par diffusion basés sur l’adsorption dans un liquide.
Le présent document traite des exigences à destination des développeurs de méthodes et/ou des fabricants.
NOTE         Pour les besoins du présent document, un fabricant peut être toute entité commerciale ou non commerciale.

Zrak na delovnem mestu - Plini in pare - Zahteve za vrednotenje merilnih postopkov z difuzijskimi vzorčevalniki (ISO 23320:2022)

Ta dokument določa zahteve glede zmogljivosti in preskusne metode v predpisanih laboratorijskih pogojih za vrednotenje difuzijskih vzorčevalnikov ter postopke za uporabo teh vzorčevalnikov pri določevanju plinov in pare v ozračju na delovnem mestu.
Ta dokument se uporablja za difuzijske vzorčevalnike in merilne postopke za uporabo teh vzorčevalnikov, v katerih vzorčenje in analiza potekata v ločenih fazah.
Ta dokument se ne uporablja za:
–   difuzijske vzorčevalnike, ki se uporabljajo za neposredno določanje koncentracij;
–   difuzijske vzorčevalnike, ki temeljijo na vpijanju v tekočino.
Ta dokument obravnava zahteve za razvijalce metode in/ali proizvajalce.
OPOMBA:   Za namene tega dokumenta je proizvajalec lahko kateri koli komercialni ali nekomercialni subjekt.
