Aerospace series - 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 capable of being successfully and reliably deployed in air and underwater, for use by adults only.
This document is applicable to compressed air and hybrid rebreather designs of EBS. It does not apply to EBS that cannot be successfully and reliably deployed underwater.

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

Série aérospatiale - Systèmes de ventilation d'urgence (EBS) de giravion - 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. Il s’applique aux EBS pouvant être correctement déployés à l’air libre et sous l'eau, destinés à être utilisés uniquement par des adultes.
Le présent document s'applique aux modèles d'EBS à air comprimé ainsi qu’à masque à recirculation hybride. Il ne s’applique pas aux EBS ne pouvant pas être correctement déployés sous l'eau.

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

Ta 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 za sisteme EBS, ki jih je mogoče uspešno in zanesljivo uvede v zraku in pod vodo ter so namenjeni samo odraslim osebam.
Ta dokument se uporablja za modele EBS dihalnih aparatov na stisnjen zrak in hibridne dihalne aparate z zaprtim krogom. Ne velja za sisteme EBS, ki jih ni mogoče uspešno in zanesljivo uvesti pod vodo.
