22、ropean Standard specifies practical performance tests for 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 ca

23、nnot be assessed by tests described in other standards. 2 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.

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

29、nning and wearing the device in accordance with the information supplied by the manufacturer perform activities in simulation 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, accou

30、nt shall be taken of any national regulations concerning the medical history, examination or supervision of the test subjects. 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 satisfactor

31、y for the tasks involved. The necessity for a medical examination before the tests and for medical supervision during them 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: -

32、 name; - age: - sex; - height; - weight. 6.3 Preparation of test samples Before testing, examine the device to see that it 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 te

33、sts specified in the relevant European Standard for the respiratory protective device. 6.4 Ambient conditions The test shall 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

34、 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. 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 th

35、e following shall be recorded individually and in private: a) ease of donning and doffing; b) head harness (if fitted) - .e. donning and doffing, adjustability, security and comfort; O BSI 03-2001 STD-BSI BS EN 23274-2-ENGL 2001 m Lb24bb9 0900473 939 Page 6 EN 13274-212001 c) comfort of facepiece; d

Ask the test subje

46、cts to read the manufacturers fitting 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

47、“Yes“, continue the test. If the answer 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

48、this is done the relevant section of the 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 othewise specified in the relevant device standard. The activities themselves

49、 are selected from those given in Table 1. The activities shall be continuous, without removal of the device.
