Rotorcraft - Emergency Breathing Systems (EBS) - Requirements, testing and marking

This document specifies requirements for Emergency Breathing Systems (EBS) for use by helicopter crew and passengers in the event of a ditching or water impact, to ensure minimum levels of performance. It applies to EBS for use by adults only.
Two categories of EBS are addressed by this standard; Category A EBS capable of being successfully deployed in air and underwater and Category B EBS capable of being successfully deployed in air but not underwater.
This document is applicable to compressed air, rebreather and hybrid rebreather designs of EBS.

Drehflügler - Notfallbeatmungssystem (EBS) - Anforderungen, Prüfung und Kennzeichnung

Dieses Dokument legt Anforderungen an Notfallbeatmungssysteme (EBS) fest, die von der Hubschrauberbesatzung und Passagieren im Falle einer Notwasserung oder dem Aufprall auf Wasser verwendet werden, um Mindestniveaus für die Leistung sicherzustellen. Es gilt für EBS nur die Verwendung durch Erwachsene.
Diese Norm befasst sich mit zwei Kategorien von EBS; EBS der Kategorie A, die erfolgreich in der Luft und unter Wasser eingesetzt werden können, und EBS der Kategorie B, die erfolgreich in der Luft, aber nicht unter Wasser eingesetzt werden können.
Dieses Dokument ist anwendbar für Druckluft , Kreislaufatemgerät  und hybride Kreislaufatemgerät-Auslegungen von EBS.

Giravion - Système de ventilation d'urgence (EBS) - Exigences, essais et marquage

Le présent document spécifie les exigences relatives aux systèmes de ventilation d'urgence (EBS) destinés à être utilisés par l'équipage et par les passagers des hélicoptères en cas d'amerrissage forcé ou d'impact avec un plan d'eau, afin de garantir des niveaux minimaux de performance. Elle s'applique uniquement aux EBS destinés à être utilisés par des adultes.
La présente norme couvre deux catégories d'EBS : l'EBS de catégorie A pouvant être correctement déployé à l’air libre et sous l'eau, et l'EBS de catégorie B pouvant être correctement déployé à l'air libre mais pas sous l'eau.
Le présent document s'applique aux modèles d'EBS à masque à recirculation et à masque à recirculation hybride, tous deux à air comprimé.

Rotoplani - Sistem prezračevanja v sili (EBS) - Zahteve, preskušanje in označevanje

Ta tehnični dokument določa zahteve za sisteme prezračevanja v sili (EBS), ki jih uporabljajo helikopterske posadke in potniki v primeru pristanka v sili ali vdora vode, da se zagotovi minimalna raven zahtevanih lastnosti. Velja samo za sisteme prezračevanja v sili (EBS), ki jih uporabljajo odrasli.
Ta standard obravnava dve kategoriji sistemov za prezračevanje v sili; EBS kategorije A, ki se lahko uspešno uvede pod vodo, in EBS kategorije B, ki se lahko uspešno uvede v zraku, ne pa pod vodo.
Ta tehnični dokument se uporablja za modele EBS dihalnih aparatov na stisnjen zrak, z zaprtim krogom in hibridne dihalne aparate z zaprtim krogom.
