24、cations which may be a complete standard or part of a standard, and practical performance tests have been carried out on complete apparatus where specified in the appropriate standard. If for any reason a complete apparatus is not tested then simulation of the apparatus is permitted provided that th
25、e respiratory characteristics and weight distribution are similar to those of the complete apparatus. 1 Scope This European Standard applies to filters with breathing hoses (non-mask mounted filters) for use as components in unassisted respiratory protective devices to be worn by the wearer, with th
26、e exception of escape apparatus and filtering facepieces. Laboratory tests and practical performance tests are included for the assessment of compliance with the requirements. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications
27、. These normative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision. For

32、32 and the nomenclature given in EN 134 apply. 4 Description Non-mask mounted filter(s) include the filter(s) and the means by which the filter(s) are connected to the facepiece. The filter(s) are normally carried by the wearer on a harness or a belt. 5 Classification Non-mask mounted filters are cl
33、assified in types and classes according to their application and protection capacity as stated in the appropriate standards EN 141, EN 143, EN 371 or EN 372. 6 Designation Respiratory protective devices meeting the requirements of this standard shall be designated as follows: Non-mask mounted (gas/c
34、ombined/particle) filter EN 12083(type) (class) (options) EXAMPLE non-mask mounted combined filter EN 12083-A2B2P3 7 Requirements 7.1 General The facepiece used shall be a full face mask according to EN 136 or a half mask according to EN 140. The connection between filter(s) and hose(s), and facepie
35、ce and hose(s) shall be robust and leaktight. When tested in accordance with 8.7 no bubbles shall escape from the apparatus after 1 min. The connection between filter(s) and hose(s) and facepiece and hose(s) may be achieved by a permanent or special type of connection or by a screw thread connection
36、 (including threads other than the standard thread). If a standard thread is used it shall be in accordance with EN 148-1. The non-mask mounted filter shall be designed or marked to prevent incorrect assembly. The effective mass supported by a half mask shall not exceed 300 g. The effective mass sup
37、ported by a full face mask shall not exceed 500 g. Non-mask mounted filters shall be used only in conjunction with facepieces having one or more inhalation valves. The particle filter of combined filters shall be on the influent side of the gas filter and shall meet the requirements for the particle
38、 filtration as described in EN 143. Testing in accordance with 8.2.

39、of materials suitable to withstand normal usage and exposures to those temperatures, humidity and corrosive environments that are likely to be encountered. Materials that may come into contact with the wearers skin shall not be known to be likely to cause skin irritation or any other adverse effect
40、to health. The finish of any part of the device likely to be in contact with the wearer shall be free from sharp edges and burrs. The filters shall meet the requirements given in the appropriate filter standards. Testing in accordance with 8.2 and 8.8. 7.3 Mechanical strength Before testing for brea
41、thing resistance and protection capacity the filter(s) shall be subjected to a test in accordance with the appropriate filter standards, simulating rough usage of the filter(s). After this treatment the filters shall show no mechanical defects and shall meet the requirements for breathing resistance
42、 and protection capacity as given in EN 141. 7.4 Breathing resistance For devices incorporating connection of non-standard thread between the hoses and the filter, the resistance imposed by filter(s) and breathing hose(s) to the flow of air shall be as low as possible and in no case exceed the value
43、s shown in the appropriate filter standards. Where the connection between hose(s) and filter(s) is given by a standard thread, the flow resistance of the breathing hose(s) without the filters(s) shall not exceed 0,3 mbar, when measured at 95 l/min continuous air flow straight position without stretc
44、hing or compressing the hose(s). Testing in accordance with 8.3. 7.5 Gas capacity, filter penetration The filters shall meet the appropriate requirements of EN 141, EN 143, EN 371 and EN 372. Testing in accordance with 8.4. 7.6 Clogging This requirement applies to filter(s) with breathing hose(s) on
45、ly which are not connected by a standard thread. When tested in accordance with EN 143, the requirements shall be satisfied, in which case the requirements for the breathing resistance apply to the flow resistance imposed by filter(s) and breathing hose(s) with the hose(s) in the straight position w
46、ithout stretching or compressing it (them). 7.7 Strength of breathing hose and couplings The breathing hose(s) and couplings intended to connect to half masks shall withstand a force of 50 N at each filter connection and at the connection to the half mask. Breathing hose(s) and couplings intended to
47、 connect to full face masks shall withstand a force of 150 N at the filter connection and at the connection to the full face mask. After testing, breathing hose(s) and couplings shall not become disconnected or physically damaged. Testing in accordance with 8.5 and 8.7. 7.8 Flammability No external
48、part of the non-mask mounted filter(s) including the breathing hose(s) and couplings shall continue to burn for more than 5 s after removal from the flame. Testing in accordance with 8.6 and prEN 12942. The non-mask mounted filter is not required to meet the other requirements of this European Stand
49、ard after being subjected to the test in 8.6. Testing in accordance with 8.6 and prEN 12942. 7.9 Breathing hose Breathing hose(s) shall permit free head movement and shall not restrict or close off the air flow under chin or arm pressure. The hose(s) shall be flexible so that the facepiece fit is maintained during head movements. Testing in accordance with 8.8. 7.10 Harness or belt The harness or belt shall ensure comfortable and safe wearing of the non-mask mounted filter. The harness or belt shall
