Introduction This European Standard is intended as a supplement to the specific device standards for respiratory protective devices. Test methods are spe

20、cified for complete, or parts of, devices. If deviations from the test method given in this European Standard are necessary, these deviations will be specified in the relevant device standard.Page 4 EN 13274-2:2001 BSI 03-2001 1 Scope This European Standard specifies practical performance tests for

21、respiratory protective devices, except for diving apparatus. The purpose of these tests is to subjectively assess certain properties, characteristics and functions of the device, when worn by test subjects in simulated practical use, which cannot be assessed by tests described in other standards. 2

22、Normative references This 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 listed hereafter. For dated references subsequent amendments to, or revisio

23、ns of, any of these publications, apply to this European Standard only when incorporated in it by amendment or revision. For undated references the latest edition of the publication referred to applies (including amendments). EN 132, Respiratory protective devices Definitions of terms and pictograms

24、. 3 Terms and definitions For the purposes of this European Standard, the terms and definitions given in EN 132 apply. 4 Prerequisites In order to implement this part of EN 13274, at least the following parameters need to be specified in the relevant device standard: - the number of samples; - devic

25、e preparation; - any prior conditioning or testing; - the number and selection of test subjects; - activity sequence, if relevant; - deviations; - pass/fail criteria; - identification of activities (by number in Table 1), and specification of relevant times including the total time; 5 General test r

26、equirements 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 subject to a tolerance of 5 %. Unless otherwise specified, the ambient temperature for testing

27、shall be between 16 C and 32 C and the temperature limits shall be subject to an accuracy of 1 C.Page 5 EN 13274-2:2001 BSI 03-2001 6 Test methods 6.1 Principle Test subjects donning and wearing the device in accordance with the information supplied by the manufacturer perform activities in simulati

28、on of practical use. They are then asked to assess the device subjectively and comment accordingly. 6.2 Test subjects Before performing any tests involving human subjects, account shall be taken of any national regulations concerning the medical history, examination or supervision of the test subjec

29、ts. Test subjects who are experienced in wearing the type of respiratory protective device being tested shall be used. The medical condition of the subjects shall be satisfactory for the tasks involved. The necessity for a medical examination before the tests and for medical supervision during them

30、is at the discretion of the appropriate responsible person of the test house. Prior to the tests the following data shall be recorded, but not reported, for each test subject: - name; - age; - sex; - height; - weight. 6.3 Preparation of test samples Before testing, examine the device to see that it

31、is in good working condition and that it can be used without hazard. Practical performance tests shall only be performed following satisfactory testing against the laboratory tests specified in the relevant European Standard for the respiratory protective device. 6.4 Ambient conditions The test shal

32、l be performed in a normally lit area with a temperature from 16 C to 32 C and relative humidity from 30 % to 80 %. The actual conditions of temperature and humidity and noise level shall be recorded. 6.5 Low temperature conditions The test shall be carried out at either 6 C to 9 C or 15 C to 20 C.

33、The actual temperature shall be recorded. 6.6 Assessments During the tests the device shall be subjectively assessed by each wearer, and after the test, comments on the following shall be recorded individually and in private: a) ease of donning and doffing; b) head harness (if fitted) i.e. donning a

34、nd doffing, adjustability, security and comfort;Page 6 EN 13274-2:2001 BSI 03-2001 c) comfort of facepiece; d) compatibility with skin; e) comfort of body harness, belt and breathing bag (if fitted); f) comfort of wearing and balance of the device; g) clarity of vision through the visor of the facep

35、iece (if fitted), including misting, for example the visibility of a sign (e.g. an Exit sign) consisting of letters 150 mm in height at a distance of 6 m; h) field of vision, to be determined with the component normally to be used with the facepiece fitted to it; i) speech transmission; j) security

36、of fastenings and couplings(if fitted); k) accessibility of controls and pressure gauge (if fitted); l) ease of operation and ease of interpretation of the checking facility for the manufacturers minimum design flow rate (if fitted); m) inadvertent operation of the on-off switch or of any means of c

37、hanging flow rate or classification of the device (if fitted); n) operation and effectiveness of warning device (if fitted); o) maneuverability/kinking of breathing hose, air supply hose or compressed air supply tube (if fitted); p) freedom of head movement with respect to breathing hose (if fitted)

38、; q) comfort of breathing (e.g. temperature, pressure, quantity); r) any stress or discomfort caused by the flow rate or distribution of the air; s) ease of operation of supplementary air supply (if fitted); t) ease of obtaining ambient air or the use of any emergency system provided (if applicable)

39、; u) effectiveness of saliva trap (if fitted); v) any other comments regarding the design of the device or the materials used in its construction; w) any comments regarding other characteristics specified within the device standard; x) any other comments reported by the wearer.Page 7 EN 13274-2:2001

40、 BSI 03-2001 6.7 Activities Each subject shall wear either clothing specified by the manufacturers instructions for use with the device under test, or clothing appropriate to the conditions in the test house and the activities to be performed. Ask the test subjects to read the manufacturers fitting

41、instructions and if necessary show them how to fit the device correctly in accordance with the fitting instructions. Ask the test subject to fit the device, selecting the correct size if appropriate. Ask each test subject “Does the device fit?” If the answer is “Yes”, continue the test. If the answe

42、r is “No”, take the test subject off the panel and report the fact. Before starting the test check visually whether the device has been fitted correctly. Inform the test subjects that if they wish to adjust the device during the test they may do so. However, if this is done the relevant section of t

43、he test will be repeated having allowed the system to re-settle. The sequence of activities shall be at the discretion of the appropriate responsible person from the test house, unless otherwise specified in the relevant device standard. The activities themselves are selected from those given in Tab

44、le 1. The activities shall be continuous, without removal of the device. NOTE: Due regard should be given to ergonomic good practice and manual handling statutory requirements Table 1 Activities for practical performance tests Number Activity Conditions 1 Test at rest, without performing any work.
