Respiratory equipment - Compressed gases for breathing apparatus

This European Standard specifies requirements for the quality of compressed gas supplied for mixing or use in respiratory protective devices and hyper- and hypobaric operations. Account is taken of the use of compressed gases for normal atmospheric pressure as well as for hyper- and hypobaric pressures.
This European Standard does not apply to compressed gases used for medical purposes or for aerospace applications.

Atemgeräte - Druckgase für Atemschutzgeräte

Diese Europäische Norm legt Anforderungen an die Qualität von Druckgasen fest, die für das Mischen oder die Anwendung in Atemschutzgeräten und Über- und Unterdrucksituationen zur Verfügung gestellt werden. Es wird der Einsatz von Druckgasen sowohl bei normalem Atmosphärendruck als auch bei Über- und Unterdruck berücksichtigt.
Diese Europäische Norm gilt nicht für Druckgase, die für medizinische Zwecke oder in der Luftfahrt angewendet werden.

Appareils de protection respiratoire - Gaz comprimés pour appareil de protection respiratoire

La présente Norme européenne spécifie les exigences pour la qualité du gaz comprimé fourni pour le mélange ou l’utilisation dans les appareils de protection respiratoire et des opérations hyper et hypobare. L'utilisation de gaz comprimés à la pression atmosphérique normale ainsi qu’à des pressions hyper et hypobare est prise en compte.
La présente Norme européenne ne s'applique pas aux gaz comprimés à usage médical ou aux applications aérospatiales.

Oprema za varovanje dihal - Stisnjeni plini za dihalne aparate

Standard EN 12021 določa zahteve za kakovost stisnjenega plina, dobavljenega za mešanje ali uporabo pri opremi za varovanje dihal ter pri hiper- in hipobaričnih operacijah. Upošteva se uporaba stisnjenih plinov za običajni atmosferski tlak ter tudi za hiper- in hipobarični tlak. Ta evropski standard se ne uporablja za stisnjene pline, ki se uporabljajo za medicinske namene ali za uporabo v aeronavtiki.
