Page 5EN 149:2001ForewordThis European Standard 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of anidentical text or by endorsement, at the latest by October 2001, and conflicting national standards shallbe withdrawn at the latest by October 2001.This European Standard supersedes EN 149:1991.This European Standard has been prepared under a mandate given to CEN by the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 thisstandard.Annex A is informative.According to the CEN/CENELEC Internal Regulations, the national standards organizations of thefollowing countries are bound to implement this European Standard: Austria, Belgium, Czech Republic,Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway,Portugal, Spain, Sweden, Switzerland and the United Kingdom.IntroductionA 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, andpractical performance tests have been carried out successfully on complete apparatus where specifiedin the appropriate standard. If for any reason a complete apparatus is not tested then simulation of theapparatus is permitted provided the respiratory characteristics and weight distribution are similar tothose of the complete apparatus.1
ScopeThis European Standard specifies minimum requirements for filtering half masks as respiratoryprotective devices to protect against particles except for escape purposes.Laboratory and practical performance tests are included for the assessment of compliance with therequirements.2 Normative referencesThis European Standard incorporates by dated or undated reference, provisions from other publications.These normative references are cited at the appropriate place
