Page 5EN 143:2000g227 BSI 2006IntroductionA given respiratory protective device can only be approved when the individual components satisfy therequirements of the test specifi
28、cation which may be a complete standard or part of a standard, and practicalperformance tests have been carried out successfully on complete apparatus where specified in the appropriatestandard. If for any reason a complete apparatus is not tested then simulation of the apparatus is permittedprovide
29、d the respiratory characteristics and weight distribution are similar to those of the complete apparatus.1 ScopeThis European Standard specifies particle filters for use as components in unassisted respiratory protectivedevices with the exception of escape apparatus and filtering facepieces.Laborato
30、ry tests are included for the assessment of compliance with the requirements.Some filters complying with this European Standard may also be suitable for use with other types of respiratoryprotective devices and, if so, shall be tested and marked according to the appropriate European Standard.2 Norma

34、Air enters the particle filter(s) and passes to the facepiece after removal of particles.5 ClassificationParticle filters are classified according to their filtering efficiency. There are three classes of particle filters:P1, P2 and P3 in ascending order of the filtering efficiency.The protection pr
35、ovided by a P2- or P3-filter includes that provided by the filter of lower class or classes.EN 13274-5:2001, Respiratory protective devices - Methods of test - Part 5: Climatic conditions. ! “!3.1 Re-usable filter Filter intended to be used for more than a single shift “In addition, filters may be c
36、lassified as single shift use only, or may be re-usable (more than one shift). ! “Page 6EN 143:2000g227 BSI 20066 DesignationParticle filters meeting the requirements of this European Standard shall be designated in the following manner:7 Requirements7.1 GeneralIn all tests, all test samples shall m
37、eet the requirements.7.2 Nominal values and tolerancesUnless otherwise specified, the values stated in this European Standard are expressed as nominal values.Except for temperature limits, values which are not stated as maximum or minimum shall be subject to atolerance of g177 5 %. Unless otherwise
38、specified, the ambient temperature for testing shall generally be(24 g177 8) g176C but for the mechanical tests (20 g177 10) g176C. Other temperature limits shall be subject to an accuracy ofg177 1 g176C.7.3 Visual inspectonThe visual inspection shall be carried out prior to laboratory tests and as
39、specified elsewhere in this standard.Testing shall be done in accordance with 8.2.7.4 ConnectionThe connection between filter(s) and facepiece or other device(s) with which it is intended to be used shall berobust and leaktight.The connection between filter and facepiece may be achieved by a permane
40、nt or special connector or by ascrew 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 possibleto connect it to a thread conformi
41、ng 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 preventincorrect assembly.Testing shall be done in accordance with 8.2.7.5 MassThe maximum mass of filter(s) designated to be used directly connected to a half
42、 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 8.1.7.6 Multiple filtersWhere filtering devices are designed to use more than one filter (i.e. multiple filter device), through which theflow is
43、 proportioned, all requirements given in this European Standard are to be met by the complete set offilters (e.g. the total mass of a filter set designated to be used directly connected to a half mask shall not exceed300 g).If, however, it is possible that the single filter of a multiple filter devi
44、ce may be used alone, then the requirementsat the full flow rate for the tests, as stated in this European Standard, shall be met. particle filter EN 143, filter type, class, option e.g. particle filter EN 143 P3 NR ! “Page 7EN 143:2000g227 BSI 2006In the information supplied by the manufacturer all
