This method or other test methods may be applicable

25、to specifications for complete helmets or parts thereof, and may be referenced in the appropriate helmet standards. Performance requirements are given in the appropriate helmet standard, as are such prerequisites as the number of samples, pre-conditioning, preparation of samples for the tests, seque

26、nce and duration of testing and assessment of test results. If deviations from the test method given in this standard are necessary, these deviations will be specified in the appropriate helmet standard. 1 Scope This European Standard describes methods of test for protective helmets. The purpose of

27、these tests is to enable assessment of the performance of the helmet as specified in the appropriate helmet standard. This European Standard specifies conditions and conditioning to be used when testing protective helmets. 2 Terms and definitions For the purposes of this European Standard, terms and

28、 definitions used in this standard may be found in the appropriate helmet standard. 3 Prerequisites In order to implement this European Standard, at least the following parameters shall be specified in the appropriate helmet standard: a) number of samples; b) preparation of samples; c) sequence of c

29、onditioning; d) sequence of tests; e) temperatures to be used. 4 Test methods 4.1 General Several methods are specified. The appropriate helmet standard will state which of these method(s) is/are applicable. 4.2 Testing atmosphere Testing in accordance with all parts of EN 13087 shall be performed i

30、n an atmosphere with a temperature of (22 5) C and a relative humidity of (55 30) %. This atmosphere may be referred to as laboratory ambient conditions. 4.3 Conditioning cabinet The temperature and artificial ageing conditioning cabinets shall be sufficiently large to ensure that the helmets do not

31、 touch one another or the sides of the cabinet. They shall be fitted with a fan to ensure effective air circulation. 4.4 High temperature conditioning Samples shall be maintained at one of the following temperatures, as specified in the appropriate helmet standard, for a period of time between 4 h a

32、nd 24 h: (+50 or +40) C with a tolerance of 2 C in each case. 4.5 Low temperature conditioning Samples shall be maintained at one of the following temperatures, as specified in the appropriate helmet standard, for a period of time between 4 h and 24 h: (0, 10, 20, 30, 40) C, with a tolerance of 2 C

33、in each case.EN 13087-1:2000 BSI 22 March 2002 5 4.6 Water conditioning Samples shall be water conditioned by one of the following methods, as specified in the appropriate helmet standard. Tap water at a temperature not greater than 27 C shall be used for both methods. Method 1. The sample shall be

34、totally immersed in water for a period of time between 4 h and 24 h. Method 2. The sample shall be sprayed over its outer surface at a rate of nominally 1 l/min for a period of time between 4 h and 24 h. 4.7 Artificial ageing 4.7.1 Principle The sample helmet is exposed to a specified irradiation fr

35、om a xenon arc lamp. 4.7.2 Apparatus A fused silica envelope, high pressure xenon lamp of 450 watt nominal power, operated in accordance with the lamp manufacturers instructions. NOTE 1 A suitable lamp reference is XBO-450W/4. A means to ensure that the air temperature, measured at the sample positi

36、on, does not exceed 50 C. A means to support the helmets so that they are exposed to the radiation. 4.7.3 Procedure Secure the helmet so that the plane tangential to the crown of the helmet is perpendicular to the direction of radiation from the lamp and the distance between the crown of the helmet

37、and the arc of the lamp is (150 5) mm. Expose the sample to the radiation for (400 4) h. Remove the sample and allow it to return to laboratory ambient conditions (4.2). NOTE A further method for artificial ageing is described in Annex A.EN 13087-1:2000 6 BSI 22 March 2002 Annex A (informative) Arti

38、ficial ageing Procedure The helmet submitted to artificial ageing should be exposed to the radiation of a xenon arc lamp. The radiant energy of the lamp should be filtered to provide a spectral power distribution that closely approximates that of terrestrial daylight. The helmet should be fixed on a

39、 cylindrical holder concentric to the lamp and which rotates at a speed of 1 to 5 r/min around its axis. Each helmet which will subsequently be tested for shock absorption or for penetration should be orientated so that the area of test should be directed towards the lamp. The plane tangential to th

40、e shell at this point should be normal to a radius of the cylindrical holder. The radiant energy incident in the plane of the test areas should be either measured or calculated from information provided by the manufacturer of the test apparatus. The exposure interval should be adjusted so that the e

41、xposed samples receive a total energy of 1 GJ/m 2over the wavelength range 280 to 800 nm. The samples should be sprayed with distilled or demineralized water (having a conductivity below 5 mS/cm) intermittently with a cycle of 18 min of spraying and 102 min without spraying. During the latter period

42、s the measured relative humidity should be (50 5) %. The temperature within the test chamber should be measured with a black standard thermometer placed at the same distance from the lamp as the exposed test areas of the helmets. The temperature should be maintained at (70 3) C. All other test and c

43、alibration conditions for the apparatus should be in accordance with ISO 4892-1 and with ISO 4892-2, Method A. NOTE 1 Not all available test apparatus, otherwise meeting the requirements of ISO 4892, will incorporate sample holder frames of diameter sufficient to accommodate complete helmets. NOTE 2

44、 The position of the water sprays may require adjustment in order to avoid interference with the test samples. NOTE 3 The energy output of the xenon arcs should be capable of being reduced below normal operational levels, so as to maintain acceptable intensities in the sample surface plane required
