33、42 EN 404:2005 (E) 4 Foreword This document (EN 404:2005) has been prepared by Technical Committee CEN/TC 79 “Respiratory protective 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 identical text

34、or by endorsement, at the latest by October 2005, and conflicting national standards shall be withdrawn at the latest by October 2005. This document supersedes EN 404:1993. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association

35、, and supports essential requirements of EU Directive 89/686 EEC. For relationship with EU Directive 89/686 EEC, 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 following countries ar

36、e 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, Switzerland and

37、 United Kingdom. EN 404:2005 (E) 5 Introduction A given respiratory protective device can only be approved when the individual components satisfy the requirements of the test specification which may be a complete standard or part of a standard, and practical performance tests have been carried out s

38、uccessfully on complete device where specified in the appropriate standard. If for any reason a complete device is not tested then simulation of the device is permitted provided the respiratory characteristics and mass distribution are similar to those of the complete device. EN 404:2005 (E) 6 1 Sco

39、pe This document refers to filtering devices designed for protection against carbon monoxide (filter self-rescuer). It specifies minimum requirements for filter self-rescuers. This document does not apply to apparatus for work and rescue or to diving apparatus. Laboratory and practical performance t

40、ests are included for the assessment of compliance with the requirements. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenc

41、ed document (including any amendments) applies. EN 132:1998, Respiratory protective devices Definitions of terms and pictograms EN 134:1998, Respiratory protective devices Nomenclature of components EN 13274-2:2001, Respiratory protective devices Methods of test Part 2: Practical performance test 3

42、Terms and definitions For the purposes of this document, the terms and definitions given in EN 132:1998 and the nomenclature given in EN 134:1998 apply. 4 Description A filter self-rescuer is a respiratory protective filtering device in a suitable packing for use in personal escape, and designed to

43、protect the wearer against carbon monoxide. It is dependent on ambient atmosphere and does not provide protection against oxygen deficient atmospheres. The filtering device consists of a mouthpiece assembly with a filter. The mouthpiece assembly of the filtering device is connected directly or indir

44、ectly to the filter(s). 5 Classification Filter self-rescuers are classified according to the minimum test duration which is defined by performing a breathing machine test in accordance with 7.6.1. Table 1 Classes of filter self-rescuers Class Minimum duration min FSR 1 A FSR 1 B 60 FSR 2 A FSR 2 B

45、75 FSR 3 A FSR 3 B 90 FSR 4 A FSR 4 B 120 In the class, the numbers 1 - 4 indicate the minimum duration time as seen in the Table 1. The letters A and B indicate the flow rates 30 l/min and 40 l/min. Devices passing “rough usage” requirements shall be marked “R”. EN 404:2005 (E) 7 NOTE The effective

46、 duration time may vary according to the work rate. 6 Requirements 6.1 General In all tests, all test samples shall meet the requirements. Wherever a test clause is referenced, all sub-clauses of the test clause shall apply, unless otherwise stated. NOTE The requirements and test methods are based o

47、n experience with existing design of filter self-rescuers incorporating Hopcalite and drier. Consideration should be given to the behaviour of designs incorporating other filtering materials. 6.2 Ergonomics The requirements of this document are intended to take account of the interaction between the

48、 wearer, the respiratory protective device, and where possible the working environment in which the respiratory protective device is likely to be used. The device shall satisfy 6.3 and 6.19. 6.3 Design The design of the device shall be such as to allow its inspection in accordance with the informati

49、on supplied by the manufacturer. The device shall be sufficiently robust to withstand the rough usage it is likely to receive in use with respect to its classification. The device shall be designed so that there are no protruding parts, sharp edges or burrs likely to be caught on projections in narrow passages or that may harm the wearer. No part of the device likely to be in contact with the wearer shall have sharp edges or burrs. The filter self-rescuer shall be designed such that the ou
