Respiratory equipment - Open-circuit umbilical supplied compressed gas diving apparatus - Part 1: Demand apparatus
This European Standard specifies minimum requirements for demand surface supplied and demand surface oriented diving apparatus to ensure a minimum level of safe operation of the apparatus. It applies to the following:
depths between 0 m and 50 m for apparatus using air, oxygen or oxygen in nitrogen mixtures;
depths between 0 m and 60 m for apparatus using oxygen, oxygen and helium or oxygen, nitrogen and helium gas mixtures;
water temperatures between 4 °C and 34 °C or outside these temperatures as specified by the manufacturer.
The requirements of this European Standard are intended to take account of the interaction between the wearer, the apparatus, and where possible the environment in which the apparatus is likely to be used.
This European Standard does not cover saturation diving systems, mini bell systems or apparatus used for oxygen decompression only.
Atemgeräte - Schlauchversorgte Leichttauchgeräte mit Druckgas - Teil 1: Lungenautomatisch gesteuerte Geräte
Diese Europäische Norm legt Mindestanforderungen für schlauchversorgte, lungenautomatisch gesteuerte Leichttauchgeräte mit Druckluft fest, um ein Mindestmaß an Sicherheit für den Betrieb des Gerätes sicher¬zustellen. Sie gilt für Folgendes:
Tiefen zwischen 0 m und 50 m für Geräte mit Luft, Sauerstoff oder Sauerstoff/Stickstoff-Gemischen;
Tiefen zwischen 0 m und 60 m für Geräte mit Sauerstoff, Sauerstoff/Helium-Gemischen oder Sauerstoff/Stickstoff/Helium-Gemischen;
Wassertemperaturen zwischen 4 °C und 34 °C oder außerhalb dieser Temperaturen, wie vom Hersteller festgelegt.
Die Anforderungen dieser Europäischen Norm sind dafür vorgesehen, die Interaktion zwischen Gerätträger, Gerät und, wo möglich, der Umgebung, in der das Gerät wahrscheinlich benutzt werden soll, zu berück¬sichtigen.
Diese Europäische Norm gilt nicht für Sättigungstauchsysteme, Taucherglockensysteme und Geräte, die nur zur Sauerstoffdekompression benutzt werden.
Equipements respiratoires - Appareils de plongée narguilé à gaz comprimé et à circuit ouvert - Partie 1: Appareils à la demande
La présente norme européenne spécifie les exigences minimales qui s’appliquent aux appareils autonomes de plongée à la demande et aux appareils de plongée à la demande alimentés à partir de la surface, dans le but de garantir un niveau minimal de sécurité en fonctionnement de l’appareil. Elle s’applique :
à des profondeurs situées entre 0 m et 50 m pour les appareils utilisant de l’air, de l’oxygène ou de l’oxygène dans les mélanges à base d’azote ;
à des profondeurs situées entre 0 m et 60 m pour les appareils utilisant de l’oxygène, de l’oxygène et de l’hélium ou des mélanges d’oxygène, d’azote et d’hélium ;
à des températures d’eau comprises entre 4 °C et 34 °C ou en dehors de cette plage de températures comme spécifié par le fabricant.
Les exigences de la présente norme européenne sont conçues pour tenir compte de l’interaction entre l’utilisateur, l’appareil, et, dans la mesure du possible, l’environnement dans lequel l’appareil est susceptible d’être utilisé.
La présente norme européenne ne couvre pas les systèmes de plongée en saturation, ni les systèmes de mini-ceinture, ni les appareils utilisés uniquement pour la décompression à l’oxygène.
