5.3.2 U.V. ageing 5.3.2.1 Apparatus A high pressure xenon 450 Watt lamp with quartz casing, operated in accordance with the lamp manufacturer's instructions. A means to support the helmet so that it is exposed to the radiation. 5.3.2.2 Procedure Secure the helmet so that the vertical axis through the crown of the helmet (as worn) is perpendicular to the axis of the lamp and the distance between the crown of the helmet and the axis of the lamp is (150 ± 5) mm. Expose the helmet to the radiation for (400 ± 4) h. It shall then be removed and allowed to return to laboratory ambient conditions. NOTE The method described in Annex A may be used as an alternative. 5.3.3 åThermal plus’ conditioning The helmet shall be exposed to a temperature of (35 ± 2) °C for between 4 h and 24 h. 5.3.4 åThermal minus’ conditioning The helmet shall be exposed to a temperature of (-20 ± 2) °C for between 4 h and 24 h. 5.4 Headforms The head forms used shall comply with EN 960:2006. The sizes in Table 2 shall be used, except for determination of shock absorbing capacity, for which only size designations 495, 535, 575, 605 and 625 shall be used. SIST EN 12492:2012
