EN 142:2002 (E)4ForewordThis document EN 142:2002 has been prepared by Technical Committee CEN/TC 79 "Respiratory protectivedevices", 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of an identical text orby endorsement, at the latest by October 2002, and conflicting national standards shall be withdrawn at the latestby October 2002.This document supersedes EN 142:1989.This document has been prepared under a mandate given to CEN by the European Commission and the EuropeanFree Trade Association, and supports essential requirements of EU Directive(s).For relationship with EU Directive(s), see informative annex ZA, which is an integral part of this document.The annexes A and ZA are informative.According to the CEN/CENELEC Internal Regulations, the national standards organizations of the followingcountries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland,France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway, Portugal, Spain,Sweden, Switzerland and the United Kingdom.
EN 142:2002 (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 the appropriatestandard. If for any reason a complete apparatus is not tested then simulation of the apparatus is permittedprovided the respiratory characteristics and mass distribution are similar to those of the complete apparatus.1 ScopeThis European Standard refers to mouthpiece assemblies for respiratory protective devices, except escapeapparatus and diving apparatus.It specifies minimum requirements for mouthpiece assemblies for use as part of respiratory protective devices.Laboratory and practical performance tests are included for the assessment of compliance with the requirements.2 Normative ReferencesThis European Standard incorporates by dated or undated reference, provisions from other publications. Thesenormative references are cited at the appropriate places in the text, and the publications are listed hereafter. Fordated references, subsequent amendments to or revisions of any of these publications apply to this EuropeanStandard only when incorporated in it by amendment or revision.

EN 142:2002 (E)64 DescriptionAir enters the mouthpiece assembly and passes directly into the mouth. The exhaled air flows back either throughthe facepiece connector into the breathing apparatus (closed-circuit breathing apparatus, pendulum breathing) ordirectly to the ambient atmosphere, via the exhalation valve(s), in other types of respiratory protective devices.5 DesignationMouthpiece assemblies meeting the requirement of this European Standard shall be designated in the followingmanner:Mouthpiece assembly EN 142.6 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, themouthpiece assembly, and where possible, the working environment in which the mouthpiece assembly is likely tobe used. See annex ZA.6.3 DesignThe design of the mouthpiece assembly shall be such as to allow its inspection in accordance with themanufacturers instructions.The mouthpiece assembly shall be sufficiently robust to withstand the rough usage it is likely to receive in service.The mouthpiece assembly shall be designed so that there are no protruding parts or sharp edges likely to becaught on projections in narrow passages.The surface of any part of the mouthpiece assembly likely to be in contact with the wearer shall be free from sharpedges and burrs.The mouthpiece assembly shall be designed to ensure its full function in any orientation.The mouthpiece shall be so designed that inward leakage between lips and mouthpiece is negligible.The mouthpiece shall be so designed that the airflow is not restricted unintentionally when the mouthpice assemblyis being worn.Testing shall be done in accordance with 7.3 and 7.13.6.4 MaterialsAll materials used in the construction shall have adequate mechanical strength.Exposed parts, i.e. those which may be subjected to impact during use of the apparatus shall not be made ofaluminium, magnesium, titanium or alloys containing such proportions of these metals as will, on impact, give riseto frictional sparks capable of igniting flammable gas mixtures.Materials which come into direct contact with the wearer's skin shall not be known to be likely to cause irritation orany other adverse effect to health.
EN 142:2002 (E)7Testing shall be done in accordance with 7.3 and 7.13.6.5 Cleaning and disinfectingAll materials used shall withstand the cleaning and disinfection agents and procedures recommended by themanufacturer.Testing shall be done in accordance with 7.3 and 7.13.6.6 Resistance to temperatureFollowing the conditioning in accordance with 7.4 and after being allowed to return to ambient temperature themouthpiece assembly shall show no appreciable deformation and any incorporated threaded connector toEN 148-1 or EN 148-2 shall be gauged and shall comply with the appropriate standard.Testing shall be done in accordance with 7.3.6.7 FlammabilityParts of the mouthpiece assembly that might be exposed to a flame during use shall not burn or continue to burnfor more than 5 s after removal from the flame.Testing shall be done in accordance with 7.3 and 7.5.6.8 Demountable partsAll demountable connections shall be readily connected and secured, where possible by hand. Any means ofsealing used shall be retained in position when the connection is disconnected during normal maintenance.Testing shall be done in accordance with 7.3 and 7.13.6.9 Replaceable componentsUnless integral with the mouthpiece assembly the following components (if fitted) shall be replaceable:Head harness, connector(s), inhalation and exhalation valves.Testing shall be done in accordance with 7.3.6.10 Head harnessThe head harness shall be designed so that the mouthpiece assembly can be donned and removed easily.Testing shall be done in accordance with 7.13.The head harness shall be adjustable or self-adjusting and shall hold the mouthpiece assembly firmly andcomfortably in position.Testing shall be done in accordance with 7.13.Each strap of the head harness, buckles and other adjusting means shall withstand a pull of 50 N applied for 10 sin the direction of pulling when the facepiece is donned. No breaks or sliding of the straps shall occur.The requirement applies to the buckles and attachment lugs as well as to the straps.Testing shall be done in accordance with 7.3 and 7.6.
EN 142:2002 (E)86.11 Connection6.11.1 GeneralThe connection between the mouthpiece assembly and the apparatus may be achieved by a permanent or special(e.g. insert) type of connection or by a thread connection.Testing shall be done in accordance with 7.3.The mouthpiece
