29、15333-1:2008-04 EN 15333-1:2008 (E) 6 Introduction A given open-circuit umbilical supplied compressed gas diving apparatus can only be approved when the apparatus or apparatus sub-assemblies satisfy the requirements of the tests specified in this European Standard, and practical performance tests ha

30、ve been carried out successfully on complete apparatus where specified in this European Standard. The production of this European Standard has identified varying methods of surface supply and has separated them into two parts; equipment that supplies demand type facepieces and equipment that supplie

31、s free flow type facepieces. DIN EN 15333-1:2008-04 EN 15333-1:2008 (E) 7 1 Scope 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:

32、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

33、 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 syst

34、ems or apparatus used for oxygen decompression only. 2 Normative references The following referenced documents are indispensable for the application of this document.
