This

15、European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by October 2001, and conflicting national standards shall be withdrawn at the latest by October 2001. This European Standard has been prepared under a manda

16、te given to CEN by the European Commission and the European Free 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 standard. EN 13274-5 is one of several parts, which are as fo

17、llows: Part 1: Determination of inward leakage and total inward leakage; Part 2: Practical performance tests; Part 3: Determination of breathing resistance; Part 4: Flame tests; Part 5: Climatic conditions; Part 6: Determination of carbon dioxide content of inhalation air; Part 7: Determination of p

18、article filter penetration; Part 8: Determination of dolomite dust clogging of particle filters. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark

20、ive devices. Climatic conditions are specified for complete or parts of devices. If deviations from the climatic conditions given in this standard are necessary, these deviations will be specified in the relevant device standard. 1 Scope This European Standard specifies temperature, humidity, durati

21、on and method of application for climatic conditioning of respiratory protective devices. 2 Normative references This 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 li

22、sted hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this only when incorporated in it by amendment or revision.

24、0 30) % 3.2 dry atmosphere atmosphere where the relative humidity is less than 20 % 3.3 wet atmosphere atmosphere where the relative humidity is greater than or equal to 95 % 4 Prerequisites In order to implement this European Standard at least the following parameters need to be specified in the re

25、levant device standard: items to be tested; number of specimens; selection of conditioning phases; sequence of conditioning phases, where more than one is required; specification of any observations to be carried out; orientation and position of specimen during conditioning; condition of specimen, e

26、.g. packaged, sealed, fully assembled.Page 5 EN 13274-5:2001 BSI 06-2001 5 General test requirements Unless otherwise specified, the values stated in this European Standard are expressed as nominal values. Except for temperature limits, values which are not stated as maxima or minima shall be subjec

27、t to a tolerance of 5 %. Unless otherwise specified, the ambient temperature for testing shall be between 16 C and 32 C and the temperature limits shall be subject to an accuracy of 1 C. 6 Procedure 6.1 General In order to ensure that there is no thermal shock during the conditioning of the specimen

28、s, the temperature gradient shall be less than 2 C/min between phases at different temperatures, or between the beginning and the end of a thermal cycle. A phase for climatic conditioning shall be composed of the three parameters: temperature, relative humidity and duration, that is one of each of t

29、hose given in 6.2 to 6.4. For example: (30 3) C, wet atmosphere, (24 1) h. A cycle may consist of one or more phases. Each specimen shall be placed in the conditioning environment such that air is free to circulate around it, and such that no component of the specimen has its weight supported by ano

30、ther, unless specifically intended by the manufacturer. Separate specimens shall not be touching. 6.2 Temperature The temperatures used for climatic conditioning shall be chosen from the following. 6.2.1 Manufacturers highest recommended temperature. 6.2.2 (70 3) C. 6.2.3 (60 3) C. 6.2.4 (30 3) C. 6
