26、rmance tests have been carried out successfully 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 the respiratory characteristics and mass distribution are similar to those of
27、 the complete apparatus.

Filters
28、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 suitable for use with assisted respiratory protective devices and if so they need to be tested be tested and
29、 marked according to the appropriate European Standard. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text, and the publications are listed hereafter.
30、 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.

36、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 acidic gases and vapours as sp
37、ecified 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 For use against specific na
38、med 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 filters incorporating a parti
39、cle 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. BS EN 14387:2004+A1:2008Licensed Copy: Wang Bin, ISO/EXCHANGE CHINA STANDARDS, 29/07/2008 03:32, Uncontrolled Copy, (c) BSI8 Type HgP3 For use against mercury. The
40、se filters shall always incorporate a P3 filter 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
41、 2 medium capacity filters; Class 3 high capacity 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 an
42、d type SX gas filters and special filters are not 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,
43、 and where possible the working environment in which 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
44、 shall have sharp edges or burrs. The filter shall 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 corrosi
45、ve environments that are likely to be encountered. 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. BS

The maximum mass of filter
47、(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 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
48、and facepiece may be achieved by a permanent or special connector or a screw thread including a thread conforming to EN 148-1. 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
49、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 without 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 filter (i.e. multiple filter device), through which the flow is proportioned, all requirements given in
