25、5 (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 out successfully on complete ap
26、paratus where specified in the appropriate standard. If for any reason a complete apparatus is not tested then simulation of the apparatus is permitted provided the respiratory characteristics and weight distribution are similar to those of the complete apparatus. 1 Scope This European Standard spec
27、ifies minimum requirements for compressed air line breathing apparatus with demand valve for use with a full face mask as a respiratory protective device. Escape and diving apparatus and apparatus used in abrasive blasting operations without additional protective features are not covered by this Eur
28、opean Standard, although certain requirements addressing the use in conjunction with escape apparatus and escape conditions are given. Laboratory and practical performance tests are included for the assessment of conformance to the requirements. 2 Normative references The following referenced docume

36、erms, definitions and pictograms For the purposes of this European Standard, the terms, definitions and pictograms given in EN 132:1998, EN 134:1998 and the following apply. 3.1 compressed air line breathing apparatus with a demand valve for use with a full face mask apparatus, which is not self-con
37、tained, in which the wearer is supplied with breathable air from a source of compressed air at a maximum pressure of 10 bar 3.2 facepiece full face mask conforming to EN 136 (Class 2 or Class 3) 3.3 mobile high pressure air supply system supply system that may include a compressor, filters, compress
38、ed air pressure vessels, for use as a mobile source of breathing air 3.4 switch over device device that ensures that in the event of a malfunction or disconnection of the airline, the air supply, when airline is used in conjunction with self contained breathing apparatus, automatically switches over
39、 to the self contained air supply, without interruption of supplied air to the wearer 4 Description This apparatus, with or without positive pressure, enables the wearer to be provided with breathable air, which shall be in accordance with EN 12021, which, on inhalation, flows through a lung governe
40、d demand valve operating at negative pressure (apparatus without positive pressure), or at positive pressure (apparatus with positive pressure) to a suitable facepiece, possibly via a breathing hose. A compressed air supply tube connects the wearer to a supply of compressed air. Exhaled air flows in
41、to the ambient atmosphere via an exhalation valve. NOTE Conformance to EN 12021 can be ensured by a breathable air supply system or an additional device such as a compressed air filter system. EN 14593-1:2005 (E) 7 5 Requirements 5.1 General Unless otherwise specified, the values stated in this Euro
42、pean Standard are expressed as nominal values. Except for temperature limits, values which are not stated as maxima or minima shall be subject to a tolerance of 5 %. Unless otherwise specified, the ambient temperature for testing shall be between 16 C and 32 C and the temperature limits shall be sub
43、ject to an accuracy of 1 C. Where a test clause is referenced, all subclauses of the test clause shall apply, unless otherwise stated. 5.2 Ergonomics The requirements of this European Standard are intended to take account of the interaction between the wearer, the respiratory protective device, and
44、where possible the working environment in which the respiratory protective device is likely to be used. The device shall satisfy 5.3, 5.9 and 5.10. Testing shall be done accordance with 6.4. 5.3 Materials 5.3.1 All materials used in the construction shall have adequate resistance to deterioration by
45、 heat and adequate mechanical strength. Testing shall be done in accordance with 6.3, after any pre-conditioning according to 6.8, and any safety data sheet, if applicable, and declaration of the manufacturer related to materials used in the construction of the device. 5.3.2 Exposed parts, i.e. thos
46、e which may be subjected to impact during use of the apparatus shall not be made of aluminium, magnesium, titanium or their alloys.
