23、d 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 the respiratory characteristics and weight distribution are similar
24、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 the exception of escape apparatus and filtering facepieces. Laborato
25、ry 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.

32、rotection 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/combined/particle) filter EN 12083(type) (class) (options) EXAMPLE
33、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 facepiece and hose(s) shall be robust and leaktight. When tested in accor
34、dance 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 (including threads other than the standard thread). If a standard
35、 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 supported by a full face mask shall not exceed 500 g. Non-mask mounte
36、d 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 filtration as described in EN 143. Testing in accordance with 8.2
37、.Page 4 EN 12083:1998 BSI 1998 7.2 Materials The non-mask mounted filter including breathing hose and couplings shall be made 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
38、 come into contact with the wearers skin shall not be known to be likely to cause skin irritation or any other adverse effect 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 give
39、n in the appropriate filter standards. Testing in accordance with 8.2 and 8.8. 7.3 Mechanical strength Before testing for breathing 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(
40、s). After this treatment the filters shall show no mechanical defects and shall meet the requirements for breathing resistance 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 resist
41、ance 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 values 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) wi
42、thout the filters(s) shall not exceed 0,3 mbar, when measured at 95 l/min continuous air flow straight position without stretching 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, E
43、N 371 and EN 372. Testing in accordance with 8.4. 7.6 Clogging This requirement applies to filter(s) with breathing hose(s) only 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
44、resistance apply to the flow resistance imposed by filter(s) and breathing hose(s) with the hose(s) in the straight position without 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
45、 a force of 50 N at each filter connection and at the connection to the half mask. Breathing hose(s) and couplings intended to 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 coupli
46、ngs shall not become disconnected or physically damaged. Testing in accordance with 8.5 and 8.7. 7.8 Flammability No external 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 accorda
47、nce with 8.6 and prEN 12942. The non-mask mounted filter is not required to meet the other requirements of this European Standard 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 no
48、t 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 fil
49、ter. The harness or belt shall be adjustable and permit donning and doffing. Testing in accordance with 8.8. 7.11 Practical performance The non-mask mounted filter connected to a facepiece recommended by the manufacturer shall undergo practical performance tests under realistic conditions. The worst-case-filters shall be used. These general tests serve the purpose of checking the device for imperfections that cannot be determined by the tests described elsewhere in this standard.
