18、 Bibliography41 EN 137:2006 (E) 4 Foreword This European Standard (EN 137:2006) has been prepared by Technical Committee CEN/TC 79 “Respiratory protective devices”, the secretariat of which is held by DIN. This European Standard shall be given the status of a national standard, either by publication
19、 of an identical text or by endorsement, at the latest by May 2007, and conflicting national standards shall be withdrawn at the latest by May 2007. This document supersedes EN 137:1993. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Tra
20、de Association, and supports essential requirements of EU Directive(s). For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this document. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are
21、bound to implement this European Standard: Austria, Belgium, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerl
22、and and United Kingdom. EN 137:2006 (E) 5 Introduction A given respiratory protective device can only be approved when the individual components satisfy the requirements of the test specification which may be a complete standard or part of a standard and practical performance tests have been carried
23、 out successfully on complete apparatus where specified in the appropriate standard. If for a particular reason a complete apparatus is not tested then simulation of the apparatus is permitted provided the respiratory characteristics and mass distribution are similar to those of the complete apparat
24、us. EN 137:2006 (E) 6 1 Scope This European Standard specifies minimum performance requirements for self-contained open-circuit compressed air breathing apparatus with full face mask used as respiratory protective devices, except escape apparatus and diving apparatus. Such equipment is intended for
25、use in work situations where the risk on over pressurisation of the pressure vessels with their valves due to hot environmental conditions is low. Laboratory and practical performance tests are included for the assessment of compliance with the requirements. 2 Normative references The following refe

32、7:2006 (E) 7 3 Terms and definitions For the purposes of this document, the terms and definitions given in EN 132:1998, the nomenclature given in EN 134:1998 and the following apply. 3.1 rated filling pressure maximum allowable pressure to which the valved pressure vessel is intended to be filled 3.
33、2 rated working pressure maximum allowable pressure for which the apparatus is designed 4 Description This apparatus comprises valved pressure vessel(s) and typically body harness, lung governed demand valve, pressure indicator(s), warning device(s), connecting hoses and tubes and full face mask. It
34、 may include a pressure reducer, pressure reducer relief valve, supplementary air supply, second medium pressure connector, ambient air bypass device or other components and parts. The apparatus functions by enabling the wearer to breathe compressed air on demand. The exhaled air from the wearer the
35、n passes without re-circulation to the ambient atmosphere. 5 Classification Self-contained open-circuit compressed air breathing apparatus are classified in types as follows: Type 1: apparatus for industrial use; Type 2: apparatus for fire fighting. 6 Requirements 6.1 General In all tests all test s
36、amples shall meet the requirements. Wherever a test clause is referenced, all subclauses of the test clause shall apply, unless otherwise stated. Where fitted, auxiliary equipment identified in Annexes A and B shall in addition meet the requirements listed in those annexes. 6.2 Ergonomics The requir
37、ements of this European Standard are intended to take account of the interaction between the wearer, the self-contained open-circuit compressed air breathing apparatus, and where possible the working environment in which the self-contained open-circuit compressed air breathing apparatus is likely to
38、 be used. The device shall satisfy 6.3, 6.9 and 6.10. 6.3 Design The diameter of pressurised parts with a pressure greater than 0,5 bar downstream of the shut-off valve(s) shall not exceed 32 mm. EN 137:2006 (E) 8 The design of the apparatus shall be such as to allow its inspection in accordance wit
39、h the information supplied by the manufacturer. The apparatus shall be sufficiently robust to withstand the rough usage it is likely to receive in service with respect to its classification. The apparatus shall be designed so that there are no protruding parts or sharp edges likely to be caught on p
40、rojections in narrow passages. The surface of any part of the apparatus likely to be in contact with the wearer shall be free from sharp edges and burrs. All parts requiring manipulation by the wearer shall be readily accessible and easily distinguishable from one another by touch. All adjustable pa
41、rts and controls shall be constructed so that their adjustment is not liable to accidental alteration during use. The apparatus shall be so designed that the wearer can remove it and, while still wearing the full face mask, continue to breathe from the apparatus. The apparatus shall be designed to e
42、nsure its full function in any orientation. The main valve(s) of pressure vessel(s) shall be arranged so that the wearer can operate it (them) while wearing the apparatus. If apparatus (of the same type) are designed for use with different sizes of pressure vessels, changing of pressure vessels shal
43、l be possible without the use of special tools. Where the manufacturer claims the apparatus can be used with a different range of pressure vessels then the worst case(s) shall be identified and tested. Apparatus fitted with more than one pressure vessel may be fitted with individual valves on each p
44、ressure vessel. It shall not be possible simultaneously to fit two or more pressure vessels of different rated filling pressures to the same apparatus. It shall not be possible to fit an apparatus which is designed to operate with a lower rated working pressure to a pressure vessel with a higher rat
45、ed filling pressure. Testing shall be done in accordance with 7.3 and 7.11. The apparatus shall continue to function satisfactorily after being submerged in water. Before immersion and after removal from the water the apparatus shall meet the requirements of 6.21. Testing shall be done in accordance
46、 with 7.8. 6.4 Materials All materials used in the construction shall have adequate resistance to deterioration by heat and adequate mechanical strength. Testing shall be done in accordance with 7.3, 7.4 and 7.11 after pre-conditioning according to 6.24. Exposed parts, i.e. those which may be subjec
47、ted to impact during use of the apparatus shall not be made of aluminium, magnesium, titanium or their alloys. Materials which come into direct contact with the wearers skin shall not be known to be likely to cause irritation or any other adverse effect to health. Testing shall be done in accordance
48、 with 7.3 and 7.11. EN 137:2006 (E) 9 6.5 Cleaning and disinfecting All material shall be visibly unimpaired after cleaning and disinfection by the agents and procedures specified by the manufacturer. Testing shall be done in accordance with 7.3 and 7.11. 6.6 Mass The mass of the apparatus as ready
49、for use with full face mask and fully charged pressure vessel(s) shall not exceed 18 kg. Testing shall be done in accordance with 7.1 and 7.3. 6.7 Connections 6.7.1 General Components of the apparatus shall be readily separated for cleaning, examining and testing. All demountable connections shall be readily connected and secured, where possible by hand. Any means for sealing used shall be retained in position when the joints and couplings are disconnected during normal use
