DIN EN 14387:2008-05 EN 14387:2004+A1:2008 (E) 5 Introduction A given respiratory protective devi
23、ce 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 apparatus where specified in the appropriate standard. If fo
24、r any reason a complete apparatus is not tested then simulation of the apparatus is permitted provided the respiratory characteristics and mass distribution are similar to those of the complete apparatus. DIN EN 14387:2008-05 EN 14387:2004+A1:2008 (E) 6 1 Scope This European Standard refers to gas f
25、ilters and combined filters for use as components in unassisted respiratory protective devices. Filters for use against CO are excluded from this standard. Laboratory tests are included for the assessment of compliance with the requirements. Some filters complying with this standard can also be suit
26、able for use with assisted respiratory protective devices and if so they need to be tested be tested and marked according to the appropriate European Standard. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications.

33、ng types: Types A, B, E, K, AX and SX. Type A For use against certain organic gases and vapours with a boiling point 65 C as specified by the manufacturer. Type B For use against certain inorganic gases and vapours as specified by the manufacturer. Type E For use against sulphur dioxide and other ac
34、idic gases and vapours as specified by the manufacturer. Type K For use against ammonia and organic ammonia derivatives as specified by the manufacturer. Type AX For use against certain organic gases and vapours with a boiling point 65 C as specified by the manufacturer. For single use only. Type SX
35、 For use against specific named gases and vapours as specified by the manufacturer. 5.1.2 Multi-type gas filters Filters which are a combination of two or more of the above types excluding type SX and which meet the requirements of each type separately. 5.1.3 Combined filters Gas or multi-type gas f
36、ilters incorporating a particle filter according to EN 143. 5.1.4 Special filters Special filters are: Type NOP3 For use against nitrogen oxides, e.g. NO, NO2, NOX. DIN EN 14387:2008-05 EN 14387:2004+A1:2008 (E) 8 Type HgP3 For use against mercury. These filters shall always incorporate a P3 filter
37、according to EN 143 and may be combined with each other and/or types specified under 5.1.1 except for type SX. 5.2 Classes of filters Gas filters of types A, B, E and K are classified in terms of capacity as follows: Class 1 low capacity filters; Class 2 medium capacity filters; Class 3 high capacit
38、y filters. The protection provided by a class 2 or class 3 filter includes that provided by the corresponding filter of lower class or classes. The classification of combined filter(s) includes that of particle filter(s) according to EN 143. Type AX and type SX gas filters and special filters are no
39、t classified. 6 Requirements 6.1 General In all tests, all test samples shall meet the requirements. 6.2 Ergonomics The requirements of this standard are intended to take account of the interaction between the wearer, the respiratory protective device, and where possible the working environment in w
40、hich the respiratory protective device is likely to be used. See annex ZA. 6.3 Design The filter shall be sufficiently robust to withstand the rough usage it is likely to receive in service. No part of the filter likely to be in contact with the wearer shall have sharp edges or burrs. The filter sha
41、ll be designed to ensure its full function in any orientation. Testing shall be done in accordance with 7.3. 6.4 Materials The filter shall be made of suitable material to withstand normal usage and exposures to those temperatures, humidity and corrosive environments that are likely to be encountere
42、d. Internally it shall withstand corrosion by the filtering media. Any material of the filter media or any gaseous products that may be released by the air flow through the filter shall not be known to constitute a hazard or nuisance for the wearer. DIN EN 14387:2008-05 EN 14387:2004+A1:2008 (E) 9 T
43、esting shall be done in accordance with 7.3. 6.5 Mass The maximum mass of filter(s) designated to be used directly connected to a half mask is 300 g. The maximum mass of filter(s) designated to be used directly connected to a full face mask is 500 g. Testing shall be done in accordance with 7.1. 6.6
44、 Connection The connection between filter(s) and facepiece or other device(s) with which it is intended to be used shall be robust and leaktight. The connection between filter and facepiece may be achieved by a permanent or special connector or a screw thread including a thread conforming to EN 148-
45、1. Threads conforming to EN 148-2 or EN 148-3 shall not be used. If the filter is designated to be used on a multiple filter facepiece or has any other thread, it shall not be possible to connect it to a thread conforming to EN 148-1, EN 148-2 or EN 148-3. The filter shall be readily replaceable wit
46、hout use of special tools and shall be designed or marked to prevent incorrect assembly. The particle filter of combined filters shall be on the influent side of the gas filter. Testing shall be done in accordance with 7.3. 6.7 Multiple filters Where respirators are designed to use more than one fil
47、ter (i.e. multiple filter device), through which the flow is proportioned, all requirements given in this European Standard are to be met by the complete set of filters (e.g. the total mass of a filter set designated to be used directly connected to a half mask shall not exceed 300 g). If, however,
48、it is possible that a single filter of a multiple filter device may be used alone, then the requirements of the full flow rate for the tests, as stated in this European standard, shall be met. In the information supplied by the manufacturer all necessary information on how to use multiple filters sh
49、all be given. Testing shall be done in accordance with 7.1 and 7.3. 6.8 Packaging Filters shall be offered for sale packaged in such a way that they are protected against mechanical damage or visible contamination before use. Where appropriate, filters shall be factory sealed to protect the filter media against environmental influences in such a way that the breaking of the factory sealing can be identified. Testing shall be done in accordance with 7.3. DIN EN 14387:2008-05 EN 14387:2004+A1:2008 (E) 10 6.9 Mecha
