Workplace exposure - Procedures for measuring gases and vapours using pumped samplers - Requirements and test methods

This European Standard 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 European Standard is applicable to pumped samplers and measuring procedures using these samplers in which sampling and analysis are carried out in separate stages.
This European Standard 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).

Exposition am Arbeitsplatz - Messung von Gasen und Dämpfen mit pumpenbetriebenen Probenahmeeinrichtungen - Anforderungen und Prüfverfahren

Diese Europäische Norm legt Anforderungen an die Leistungsfähigkeit und Prüfverfahren für die Evaluierung
von pumpenbetriebenen Sammlern unter vorgegebenen Laborbedingungen fest, die in Verbindung mit einer
Luftsammelpumpe verwendet werden, sowie Verfahren, die diese Sammler zur Bestimmung von Gasen und
Dämpfen in der Arbeitsplatzatmosphäre verwenden.
Diese Europäische Norm gilt für pumpenbetriebene Sammler und Messverfahren, die diese Sammler, bei
denen Probenahme und Analyse in getrennten Schritten vorgenommen werden, verwenden.
Diese Europäische Norm gilt nicht für:
- pumpenbetriebene Sammler, die zur direkten Konzentrationsbestimmung verwendet werden, z. B. Prüfröhrchen
mit Längenanzeige;
- Sammler, deren Funktionsweise auf Sorption in einer Flüssigkeit und anschließender Analyse der Lösung
beruht (Gaswaschflaschen).

Exposition sur les lieux de travail - Procédures pour le mesurage des gaz et vapeurs à l'aide de dispositifs de prélèvement par pompage - Exigences et méthodes d'essai

La présente Norme européenne spécifie les exigences de performances et les méthodes d'essai, dans des conditions de laboratoires prescrites, pour l'évaluation des dispositifs de prélèvement par pompage employés conjointement avec une pompe de prélèvement d'air, ainsi que pour l'évaluation des procédures utilisant ces dispositifs de prélèvement pour la détermination des gaz et des vapeurs dans les atmosphères des lieux de travail.
La présente Norme européenne est applicable aux dispositifs de prélèvement par pompage et aux procédures de mesurage utilisant ces dispositifs de prélèvement pour lesquels le prélèvement et l'analyse sont effectués dans des étapes séparées.
La présente Norme européenne n'est pas applicable :
-   aux dispositifs de prélèvement par pompage utilisés pour la détermination directe des concentrations, par exemple des tubes détecteurs à plage colorée ;
-               aux dispositifs de prélèvement basés sur l'adsorption dans un liquide et suivie de l'analyse de la solution (barboteurs).

Izpostavljenost na delovnem mestu - Postopki za merjenje plinov in par z vzorčevalniki s črpanjem - Zahteve in preskusne metode

Ta evropski standard določa zahteve za zmogljivost in preskusne metode pod predpisanimi laboratorijskimi pogoji za vrednotenje vzorčevalnikov s črpanjem, ki se uporabljajo v povezavi s črpalko za vzorčenje zraka, in postopkov, pri katerih se uporabljajo ti vzorčevalniki za določevanje plinov in par v ozračju na delovnem mestu. Ta evropski standard velja za vzorčevalnike s črpanjem in merilne postopke z uporabo teh vzorčevalnikov, v katerih vzorčevanje in analiza potekata v ločenih stopnjah. Ta evropski standard ne velja za: - vzorčevalnike s črpanjem, ki se uporabljajo za neposredno ugotavljanje koncentracij, na primer detektorske cevi z dolžino barvila; - vzorčevalnike, ki se opirajo na sorpcijo v tekočino in nadaljnjo analizo raztopine (s pripomočki za ustvarjanje mehurčkov).
