Laboratory and practical performance tests are included for the assessment of compliance with the requirements.
Atemschutzgeräte - Gebläsefiltergeräte mit einem Atemanschluss ohne Dichtsitz (Haube) - Anforderungen, Prüfung, Kennzeichnung
Dieses Dokument legt Mindestanforderungen für Atemschutzgeräte (ASG) mit Gebläsefiltergerät und Atemanschluss ohne Dichtsitz fest. Es ist nicht anwendbar für Geräte, die für die Verwendung bei möglichem Sauerstoff Mangel vorgesehen sind.
Fluchtgeräte (ASG zu Fluchtzwecken) und Filter zur Verwendung gegen CO werden von diesem Dokument nicht abgedeckt.
Laborprüfungen und praktische Leistungsprüfungen sind enthalten, um die Übereinstimmung mit den Anforderungen feststellen zu können.
Appareils de protection respiratoire - Appareils filtrants à ventilation assistée avec interface respiratoire à ajustement lâche - Exigences, essais, marquage
Le présent document spécifie les caractéristiques minimales exigées des appareils de protection respiratoire (APR) filtrants à assistance motorisée avec interface respiratoire (IR) à ajustement lâche. Il ne s'applique pas aux appareils destinés à être utilisés dans des circonstances présentant ou pouvant présenter un défaut d'oxygène.
Les APR d'évacuation et les filtres pour utilisation contre le CO ne sont pas couverts par le présent document.
Il comporte des essais en laboratoire et des essais pratiques de performance pour évaluer la conformité aux exigences.
Oprema za varovanje dihal - Napajana oprema za filtriranje z vgrajenim ohlapno prilegajočim dihalnim vmesnikom - Zahteve, preskušanje, označevanje
Dokument določa minimalne zahteve za napajano opremo za filtriranje z vgrajenim ohlapno prilegajočim dihalnim vmesnikom. Ne zajema naprav, ki so zasnovane za uporabo v okoliščinah, kjer obstaja ali se lahko pojavi pomanjkanje kisika (koncentracija kisika, manjša od deleža prostornine 17 %).
Ta dokument ne zajema opreme za varovanje dihal za izhod v sili.
Vključeni so tudi laboratorijski in praktični preskusi za ocenjevanje skladnosti z zahtevami.
