3、 the UK implementation of EN 15333-1:2008. The UK participation in its preparation was entrusted by Technical Committee PH/4, Respiratory protection, to Subcommittee PH/4/7, Underwater breathing apparatus.A list of organizations represented on this committee can be obtained on request to its secreta

4、ry.BSI, as a member of CEN, is obliged to publish EN 15333-1:2008 as a British Standard. However, attention is drawn to the fact that during the development of this European Standard, the UK committee voted against its approval as a European Standard. The reason for this disapproval is as follows: T

5、he scope of EN 15333-1:2008 states that “. it applies to a maximum depth of 60 m for apparatus using oxygen, oxygen and helium or oxygen, nitrogen and helium gas mixtures”. Further, the function testing required in the standard at subclause 6.13.4.c) states that “two dives are to be conducted by eac

6、h diver of which at least one dive to be completed at the maximum depth for each relevant gas mixture under controlled conditions”. The UK Diving at Work Regulations 1997 limit surface-supplied diving to a maximum depth of 50 metres; thus UK law does not permit equipment with a maximum depth greater

7、 than 50 m to be tested to this standard. As a result, it is the view of BSI Committee PH/4/7 that the mandatory requirement to conduct practical performance tests (dives) to the maximum depth of each relevant gas is unnecessary.This publication does not purport to include all the necessary provisio

BS EN 15333-1:2008EN 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 requirem

34、ents of the tests specified in this European Standard, and practical performance tests have 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

35、into two parts; equipment that supplies demand type facepieces and equipment that supplies free flow type facepieces. BS EN 15333-1:2008EN 15333-1:2008 (E) 7 1 Scope This European Standard specifies minimum requirements for demand surface supplied and demand surface oriented diving apparatus to ensu

36、re 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

37、 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 u

38、sed. This European Standard does not cover saturation diving systems, mini bell systems or apparatus used for oxygen decompression only. 2 Normative references The following referenced documents are indispensable for the application of this document.
