39、purposes of this European Standard, the terms and definitions given in EN 132:1998 and the nomenclature given in EN 134:1998 apply. 4 Description 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)

40、either via a pressure reducer and a lung governed demand valve or a lung governed demand valve connected to the half mask. The exhaled 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

41、harness, lung governed demand valve, pressure indicator(s), warning device (optional), connecting hoses and tubes and a half mask. 5 Classification Lung governed demand compressed air escape apparatus are classified according to the rated working duration (see 6.23.1) which is defined by performing

42、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 duration 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 consi

43、dered to be the classification. NOTE It should be recognised that the effective duration may vary according to the breathing rate. 6 Requirements 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 appl

44、y, 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 working environment in which the apparatus is likely to be used. The device shall satisfy 6.3, 6.8 and 6.9.

45、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 activities when carried in accordance with the manufacturers instructions. The apparatus shall be so designed that there are no pr

46、otruding parts or sharp edges likely to be caught on projections in narrow passages or that may hurt the wearer. EN 14529:2005 (E) 7 The apparatus shall be designed to ensure its full function in any orientation. The ready for use state of the apparatus shall identify the pressure in the pressure ve

47、ssel(s) prior to use and during storage. In the ready for use state the half mask 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 opened automatically upon removal from the storage containe

48、r. In all cases, once opened, the pressure vessel seal shall be locked in the open position against inadvertent closing. If the escape apparatus is fitted with a connection for a working breathing apparatus, (e.g. airline apparatus), the connection shall be leak tight. The use of a supplementary sup

49、ply shall not be permitted. The apparatus shall not include a second medium pressure connector or an ambient air bypass. Testing shall be done in accordance with 7.3 and 7.8. 6.4 Materials The carrying container and the locking device, where present, shall be adequately protected against corrosion. The materials used shall be able to withstand temperatures and mechanical stress expected whilst being carried on the man as well as on machines and vehicles. Testing shall be done in accordance with 7.3, and 7.8 after pre-conditioning according t
