This European Standard shall be given the status of a national standard, either by
25、 publication of an identical text or by endorsement, at the latest by April 2006, and conflicting national standards shall be withdrawn at the latest by April 2006.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 supersedes EN 1146:1997. This European Standard has been prepared under a mandate given to CEN/CENELEC by the Eu
26、ropean Commission and the European Free Trade Association, and supports 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 is an integral part of this European Standard. According to the CEN/CENELEC Inte
27、rnal Regulations, the national standards organizations of the following 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, Nethe
28、rlands, Norway, Poland, Portugal, Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom. EN 1146:2005 (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 Eu
29、ropean 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 permitted provided th
30、e respiratory characteristics and weight distribution are similar to those of the complete apparatus. EN 1146:2005 (E) 6 1 Scope This European Standard specifies minimum requirements for self-contained open-circuit compressed air breathing apparatus for escape only, incorporating a hood. Such equipm
31、ent is 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. Laboratory and practical performance tests are included for the assessment of compliance with the requirements. This European Standard
32、 does not apply to apparatus for work or to diving devices. 2 Normative references The following referenced documents are indispensable for the application of this European Standard.

42、s given in EN 132:1998 and the nomenclature given in EN 134:1998 apply. 4 Description Compressed air escape apparatus with hood are designed and constructed to enable the wearer to breathe air supplied to a hood from a pressure vessel(s) via a pressure reducer giving a continuous flow of air. The ex
43、haled air may pass without re-circulation from the hood 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 hood. 5 Clas
44、sification Compressed air escape apparatus with hood are classified according to the rated working duration (see 6.24.1 and 6.24.3 in accordance with 7.7 and 7.9, whatever comes first) which is defined by performing a breathing machine test in accordance with 7.7 with a minute volume of 35 l/min (20
45、 cycles/min, 1,75 l/stroke). Rated working duration is defined in steps of 5 min, starting with 5 min as a minimum, up to a maximum of 30 min rated working duration since the necessary escape time is considered to be the classification. 6 Requirements 6.1 General In all tests all test samples shall
46、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 between the wearer, the apparatus, and where possible the wo
47、rking environment in which the apparatus is likely to be used. The device shall satisfy 6.3, 6.8 and 6.26. EN 1146:2005 (E) 8 6.3 Design The diameter of pressurised parts downstream of the shut-off valve(s) shall not exceed 32 mm. The apparatus shall be designed so as not to interfere with work acti
48、vities 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. The apparatus shall be designed to ensure its full function i
49、n any orientation. The ready for use state of the apparatus shall identify the pressure in the pressure vessel(s) prior to use and during storage. In the ready for use state the hood shall be securely attached to the apparatus. In the case of a permanent installation of the apparatus in a storage container the pressure vessel seal shall be activated automatically upon removal from the storage container. In all cases, once opened, the pressure vessel seal shall be locked in the open position against inadvert
