24、oved 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 devices where specified in the appropriatestandard. If for any reason a complete
25、 device is not tested then simulation of the device is permitted providedthe respiratory characteristics and mass distribution are similar to those of the complete device.EN 403:2004 (E)61 ScopeThis European Standard refers to filtering devices with a hood for personal escape from particulate matter
26、,carbon monoxide and other toxic gases produced by fire. It specifies minimum requirements for this devicewhich is for single use. It does not cover devices designed for use in circumstances where there is or might bean oxygen deficiency (oxygen less than 17 % by volume).Two types of devices are spe
27、cified; namely, those designed to be carried on the person and those designed tobe stored.This standard specifies devices primarily designed for adult users. Some devices may not be suitable forchildren.Laboratory and practical performance tests are included for the assessment of compliance with the
28、requirements.2 Normative referencesThis European Standard incorporates by dated or undated reference, provisions from other publications.These normative references are cited at the appropriate places in the text and the publications are listedhereafter. For dated references, subsequent amendments to
29、 or revisions of any of these publications apply tothis European Standard only when incorporated in it by amendment or revision.

34、2004 (E)74 DescriptionA filtering device with a hood for self-rescue from fire (filtering smoke hood) is a respiratory protective devicedependent on the ambient atmosphere.A complete device consists of a facepiece with combined filter and, if necessary, suitable packaging. It is notintended that any
35、 disassembly or assembly be carried out by the user.The facepiece of a filtering smoke hood can be the hood itself or a full face mask, half mask, quarter mask ormouthpiece assembly connected to the hood. The combined filter is attached to the facepiece and is notreplaceable without tools.5 Classifi
36、cationDevices designed to be carried on the person are classified as M and those for storage S.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, theres
37、piratory protective device, and where possible the working environment in which the respiratory protectivedevice is likely to be used. See annex ZA.6.3 DesignThe apparatus shall be sufficiently robust to withstand the rough usage it is likely to receive in service withrespect to its classification.T
38、he apparatus shall be designed so that there are no protruding parts or sharp edges likely to be caught onprojections in narrow passages.No part of the apparatus likely to be in contact with the wearer shall have sharp edges or burrs.The apparatus shall be designed to ensure its full function in any
39、 orientation.Testing shall be done in accordance with 7.3 and 7.5.6.4 MaterialsMaterials which come into direct contact with the wearers skin shall not be known to be likely to causeirritation or any other adverse effect to health.All metallic parts shall be corrosion-resistant or protected against
40、corrosion e.g. by packaging.If materials sensitive to humidity are used in the device, they shall be protected against the effects of humiditye.g. by suitable packaging.Testing shall be done in accordance with 7.3, 7.4 and 7.5.EN 403:2004 (E)86.5 MassThe mass of the ready-for-use device without pack
41、aging or carrying device shall not exceed 1000 g.Testing shall be done in accordance with 7.1.6.6 ConditioningPrior to laboratory or practical performance tests all test specimen shall be conditioned.Testing shall be done in accordance with 7.4.6.7 ConnectionsConnections between components shall be
42、designed such that they cannot be readily separated by the user.Testing shall be done in accordance with 7.3.The connection between filter and hood assembly shall withstand axially a tensile force of 50 N.Testing shall be done in accordance with 7.12.6.8 PackagingThe packaging shall be easy to open
43、without tools.Testing shall be done in accordance with 7.3.6.9 Practical performanceThe complete apparatus shall undergo practical performance tests. These general tests serve the purpose ofchecking the apparatus for imperfections that cannot be determined by the tests described elsewhere in thissta
44、ndard.Where, in the opinion of the test house, approval is not granted because practical performance tests show theapparatus has imperfections related to wearers acceptance, the test house shall provide full details of thoseparts of the practical performance tests which revealed these imperfections.
45、 This will enable other test housesto duplicate the tests and assess the results thereof.Testing shall be done in accordance with 7.5.6.10 Leakage6.10.1 Inward leakage excluding filter penetration (breathing zone)For filtering smoke hoods fitted in accordance with the instructions for use, at least
46、46 out of the 50 individualresults for the inward leakage over each of the exercise periods as defined in 7.6.1 (i.e. 10 subjects x5 exercise periods) shall be not greater than5 %and, in addition, at least 8 out of the 10 individual wearer arithmetic means (10 subjects) for the inwardleakage, averag
