Workplace exposure - Measurement of exposure by inhalation to chemical agents - Strategy for testing compliance with occupational exposure limit values

This European Standard specifies a strategy to perform representative measurements of exposure by inhalation to chemical agents in order to demonstrate the compliance with occupational exposure limit values (OELVs).
This European Standard is not applicable to OELVs with reference periods less than 15 min.

Exposition am Arbeitsplatz - Messung der Exposition durch Einatmung chemischer Arbeitsstoffe - Strategie zur Überprüfung der Einhaltung von Arbeitsplatzgrenzwerten

Diese Europäische Norm legt eine Strategie zur Durchführung repräsentativer Expositionsmessungen in Bezug auf die Inhalation chemischer Arbeitsstoffe fest, um die Einhaltung von Beurteilungsmaßstäben (OELVs) nachweisen zu können.
Diese Europäische Norm ist nicht anwendbar auf OELVs mit Referenzdauer von weniger als 15 min.

Exposition sur les lieux de travail - Mesurage de l'exposition par inhalation d'agents chimiques - Stratégie pour vérifier la conformité à des valeurs limites d'exposition professionnelle

La présente Norme européenne spécifie une stratégie pour effectuer des mesurages représentatifs de l’exposition par inhalation à des agents chimiques afin de démontrer la conformité aux valeurs limites d’exposition professionnelle (VLEP).
La présente Norme européenne n’est pas applicable aux VLEP dont les périodes de référence sont inférieures à 15 min.

Izpostavljenost na delovnem mestu - Merjenje izpostavljenosti pri vdihavanju kemičnih agensov - Strategija preskušanja skladnosti z mejnimi vrednostmi za poklicno izpostavljenost

Ta evropski standard določa strategijo za izvajanje reprezentativnih meritev izpostavljenosti kemičnim snovem zaradi vdihavanja z namenom dokazovanja skladnosti z mejnimi vrednostmi za poklicno izpostavljenost.
