EN 14387:2004 (E)4ForewordThis document (EN 14387:2004) has been prepared by Technical Committee CEN/TC 79 “Respiratoryprotective devices”, the secretariat of which is held by DIN.This European Standard shall be given the status of a national standard, either by publication of an identicaltext or by endorsement, at the latest by July 2004, and conflicting national standards shall be withdrawn at thelatest by July 2004.This document has been prepared under a mandate given to CEN by the EuropeanCommission and the European Free Trade Association, and supports essential requirements of EUDirective(s).For relationship with EU Directive(s), see informative annex ZA, which is an integral part of this document.According to the CEN/CENELEC Internal Regulations, the national standards organizations of the followingcountries are bound to implement this European Standard: Austria, Belgium, Cyprus, Czech Republic,Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania,Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Slovakia, Slovenia, Spain, Sweden, Switzerlandand United Kingdom.
EN 14387:2004 (E)5IntroductionA given respiratory protective device can only be approved when the individual components satisfy therequirements of the test specification 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 theappropriate standard. If for any reason a complete apparatus is not tested then simulation of the apparatus ispermitted provided the respiratory characteristics and mass distribution are similar to those of the completeapparatus.

EN 14387:2004 (E)75 Classification5.1 Types of filters5.1.1 Gas filtersGas filters are produced in one of the following types: Types A, B, E, K, AX and SX.¾ Type AFor use against certain organic gases and vapours with a boiling point > 65 °C as specified by themanufacturer.¾ Type BFor use against certain inorganic gases and vapours as specified by the manufacturer.¾ Type EFor use against sulphur dioxide and other acidic gases and vapours as specified by the manufacturer.¾ Type KFor use against ammonia and organic ammonia derivatives as specified by the manufacturer.¾ Type AXFor use against certain organic gases and vapours with a boiling point £ 65 °C as specified by themanufacturer. For single use only.¾ Type SXFor use against specific named gases and vapours as specified by the manufacturer.5.1.2 Multi-type gas filtersFilters which are a combination of two or more of the above types excluding type SX and which meet therequirements of each type separately.5.1.3 Combined filtersGas or multi-type gas filters incorporating a particle filter according to EN 143.5.1.4 Special filtersSpecial filters are:¾ Type NOP3For use against nitrogen oxides, e.g. NO, NO2, NOX.¾ Type HgP3For use against mercury.
EN 14387:2004 (E)8These filters shall always incorporate a P3 filter according to EN 143 and may be combined with each otherand/or types specified under 5.1.1 except for type SX.5.2 Classes of filtersGas filters of types A, B, E and K are classified in terms of capacity as follows:¾ Class 1low capacity filters;¾ Class 2medium capacity filters;¾ Class 3high capacity filters.The protection provided by a class 2 or class 3 filter includes that provided by the corresponding filter of lowerclass 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 not classified.6 Requirements6.1 GeneralIn all tests, all test samples shall meet the requirements.6.2 ErgonomicsThe requirements of this standard are intended to take account of the interaction between the wearer, therespiratory protective device, and where possible the working environment in which the respiratory protectivedevice is likely to be used. See annex ZA.6.3 DesignThe 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 shall be designed to ensure its full function in any orientation.Testing shall be done in accordance with 7.3.6.4 MaterialsThe 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 encountered. Internally it shall withstand corrosion bythe filtering media.Any material of the filter media or any gaseous products that may be released by the air flow through the filtershall not be known to constitute a hazard or nuisance for the wearer.Testing shall be done in accordance with 7.3.
EN 14387:2004 (E)96.5 MassThe 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 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 permanent or special connector or a screwthread 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 bepossible 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 preventincorrect 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 filtersWhere respirators are designed to use more than one filter (i.e. multiple filter device), through which the flow isproportioned, 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 300g).If, however, it is possible that a single filter of a multiple filter device may be used alone, then the requirementsof 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 shallbe given.Testing shall be done in accordance with 7.1 and 7.3.6.8 PackagingFilters shall be offered for sale packaged in such a way that they are protected against mechanical damage orvisible contamination before use.Where appropriate, filters shall be factory sealed to protect the filter media against environmental influences insuch a way that the breaking of the factory sealing can be identified.Testing shall be done in accordance with 7.3.6.9 Mechanical strength (M.S.)Filters shall be subjected to the mechanical strength test whe
