This method
23、 or other test methods may be applicable 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, pr
24、eparation of samples for the tests, sequence and duration oftesting 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
25、 for protective helmets. The purpose of 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 purpo
26、ses ofthis European Standard, terms and 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) p
27、reparation of samples; c) sequence of conditioning; 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) idare applicable. 4.2 Testing atmosphere Testing in accordance with all
28、parts ofEN 13087 shall be performed in an atmosphere with a temperature of (22 * 5) “C and a relative humidity of (55 * 30) YO. This atmosphere may be referred to as laboratory ambient conditions. 4.3 Conditioning cabinet The temperature and artificial ageing conditioning cabinets shall be sufficien
29、tly large to ensure that the helmets do not 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 s
30、tandard, for a period of time between 4 h and 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: (
31、O, -10, -20, -30,-40) OC, with a tolerance of %2 “C in each case. 4 O BSI 22 March 2002 EN 13087-1 12000 4.6 Water conditioning Samples shall be water conditioned by one ofthe following methods, as specified in the appropriate helmet standard. Tap water at a temperature not greater than 27 “C shall
32、be used for both methods. Method 1. The sample shall be 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 ofnominally 1 l/min for a period of time between 4 h and 24 h. 4.7 Artificial ageing 4.7.1 Principle The
33、 sample helmet is exposed to a specified irradiation from a xenon arc lamp. 4.7.2 Ayy u ru tus A fused silica envelope, high pressure xenon lamp of450 watt nominal power, operated in accordance with the lamp manufacturers instructions. A means to ensure that the air temperature, measured at the samp
34、le position, 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 t
35、he helmet 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 1 A suitable lamp reference is xB0-450W/4. NOTE A further method for artificial ageing is described in Annex A.
36、5 O BSI 22 March 2002 EN 13087-1 12000 Annex A (informative) Artificial 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 approxim
37、ates that of terrestrial daylight. The helmet should be fixed on a 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 oftes
38、t should be directed towards the lamp. The plane tangential to the 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
39、apparatus. The exposure interval should be adjusted so that the exposed samples receive a total energy of 1 GJ/m2 over 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 o
40、f spraying and 102 min without spraying. During the latter periods the measured relative humidity should be (50 * 5) YO. 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. Th
41、e temperature should be maintained at (70 * 3) “C. Ail other test and calibration conditions for the apparatus should be in accordance with IS0 4892-1 and with IS0 4892-2, Method A. NOTE 1 of diameter sufficient to accommodate complete helmets. NOTE 2 NOTE 3 acceptable intensities in the sample surf
42、ace plane required by this procedure. Not all available test apparatus, otherwise meeting the requirements of IS0 4892, will incorporate sample holder frames The position of the water sprays may require adjustment in order to avoid interference with the test samples. The energy output ofthe xenon ar
43、cs should be capable ofbeing reduced below normal operational levels, so as to maintain 6 O BSI 22 March 2002 EN 13087-1 12000 EU Directive 89/686/EEC, Annex II Annex ZA (informative) Clauses of this European Standard addressing essential requirements or other provisions of EU Directives Clause of t
