9、 14529:2005iWARNINGThe UK, as a member of CEN, is obliged to publish EN 14529:2005 as a British Standard. However, attention is drawn to the fact that during the development of this European Standard, the UK consistently voted against its approval as a European Standard.The reason for this disapprov
10、al is as follows. The Scope of EN 14529:2005 states that this standard “. . . specifies minimum requirements for self-contained open-circuit compressed air breathing apparatus with half mask designed to include a positive pressure lung governed demand valve for escape purposes only.“Such equipment i
11、s intended for use in work situations where the risk on overpressurisation of the pressure vessels with their valves due to hot environmental conditions is low.“This European Standard does not apply to apparatus for work and rescue or to diving apparatus.”During discussion of this standard by BSI Co
12、mmittee PH/4/13, which mirrors the work of CEN Committee TC79/SC6, the UK committee expressed the opinion that the self-contained open-circuit compressed air breathing apparatus with half mask covered in this standard is not a safe combination to be used in those emergency situations where wearers m
13、ay be exposed to other conditions (such as exposure in confined spaces to, or leaks of, noxious or toxic substances) that will, on the basis of a risk assessment in accordance with The Control of Substances Hazardous to Health Regulations 2002, require the combination to meet higher minimum performa
14、nce requirements for the protection of the wearer.Licensed Copy: Wang Bin, na, Mon Aug 07 03:47:02 BST 2006, Uncontrolled Copy, (c) BSIblankLicensed Copy: Wang Bin, na, Mon Aug 07 03:47:02 BST 2006, Uncontrolled Copy, (c) BSIEUROPEAN STANDARDNORME EUROPENNEEUROPISCHE NORMEN 14529August 2005ICS 13.34

24、) BSIEN 14529:2005 (E) 3 Foreword This European Standard (EN 14529:2005) 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 of an
25、identical text or by endorsement, at the latest by April 2006, and conflicting national standards shall be withdrawn at the latest by April 2006. This European Standard has been prepared under a mandate given to CEN/CENELEC by the European Commission and the European Free Trade Association, and supp
26、orts essential requirements of EU Directive(s) 89/686/EEC and 97/23/EEC. For relationship with EU Directive(s), see informative Annexes ZA and ZB, which are integral parts of this European Standard. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the follow
27、ing countries are 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, Slovakia, Slovenia, Spain, Sweden,

29、y be a complete European Standard or part of a European Standard and practical performance tests have been carried out successfully on complete apparatus where specified in the appropriate European Standard. If for any reason a complete apparatus is not tested then simulation of the apparatus is per
30、mitted provided the respiratory characteristics and weight distribution are similar to those of the complete apparatus. Licensed Copy: Wang Bin, na, Mon Aug 07 03:47:02 BST 2006, Uncontrolled Copy, (c) BSIEN 14529:2005 (E) 5 1 Scope This European Standard specifies minimum requirements for self-cont
31、ained open-circuit compressed air breathing apparatus with half mask designed to include a positive pressure lung governed demand valve for escape purposes only. Such equipment is intended for use in work situations where the risk on overpressurisation of the pressure vessels with their valves due t
32、o hot environmental conditions is low. This European Standard does not apply to apparatus for work and rescue or to diving apparatus. Laboratory and practical performance tests are included for the assessment of compliance with the requirements. 2 Normative references The following referenced docume

42、escription Lung governed demand compressed air escape apparatus are designed and constructed to enable the wearer to breathe air on demand from a pressure vessel(s) either via a pressure reducer and a lung governed demand valve or a lung governed demand valve connected to the half mask. The exhaled
43、air passes without re-circulation from the half mask via the exhalation valve to the ambient atmosphere. This apparatus typically comprises pressure vessel(s), body harness, lung governed demand valve, pressure indicator(s), warning device (optional), connecting hoses and tubes and a half mask. 5 Cl
44、assification Lung governed demand compressed air escape apparatus are classified according to the rated working duration (see 6.23.1) which is defined by performing a breathing machine test in accordance with 7.6.4 with a minute volume of 35 l/min (20 cycles/min, 1,75 l/stroke). Rated working durati
45、on is defined in steps of 5 minutes, starting with 5 minutes as a minimum, up to a maximum of 30 min rated working duration, since the necessary escape time is considered to be the classification. NOTE It should be recognised that the effective duration may vary according to the breathing rate. 6 Re
46、quirements 6.1 General In all tests all test samples shall meet the requirements. Wherever a test clause is referenced, all sub-clauses of the test clause shall apply, unless otherwise stated. 6.2 Ergonomics The requirements of this European Standard are intended to take account of the interaction b
47、etween the wearer, the apparatus, and where possible the working environment in which the apparatus is likely to be used. The device shall satisfy 6.3, 6.8 and 6.9. 6.3 Design The diameter of pressurised parts downstream of the shut-off valve(s) shall not exceed 32 mm. The apparatus shall be designe
48、d so as not to interfere with work activities when carried in accordance with the manufacturers instructions. The apparatus shall be so designed that there are no protruding parts or sharp edges likely to be caught on projections in narrow passages or that may hurt the wearer. Licensed Copy: Wang Bi
