EN 13087-10:2012 (E) DIN EN 13087-10:2012-043 Introduction This European Standard is intended as a supplement to the specific pro

28、duct standards for protective helmets (helmet standards). Test methods may be applicable to complete helmets or parts thereof, and may be referenced in the other helmet standards. Performance requirements are given in the appropriate helmet standard, as are such details as the number of samples, pre

29、conditioning, preparation of samples for the tests, sequence 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. EN 13087-10:2012 (E) DIN EN 13087-10:20

30、12-044 1 Scope This European Standard specifies methods of test 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 the method of test for resistance to radiant h

31、eat. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any

32、amendments) applies. EN 960:2006, Headforms for use in the testing of protective helmets EN 13087-1, Protective helmets Test methods Part 1: Conditions and conditioning 3 Terms and definitions For the purposes of this document, the terms and definitions given in this standard may be found in the app

33、ropriate helmet standard. 4 Prerequisites In order to implement this part of EN 13087, at least the following parameters shall be specified in the appropriate helmet standard: a) performance requirements; b) number of samples; c) preparation of samples; d) sequence of conditioning; e) sequence of te

34、sts; f) the heat flux intensity to be used; g) fitting instructions. 5 Methods 5.1 General Testing shall be performed in ambient conditions specified in EN 13087-1. The intensity to be used is specified in the helmet standard. EN 13087-10:2012 (E) DIN EN 13087-10:2012-045 5.2 Principle Heat radiatio

35、n of a known intensity from an infra-red source is allowed to fall onto the outer surface of a helmet mounted on an instrumented headform. The temperature of the headform surface is measured. 5.3 Apparatus 5.3.1 General The apparatus shall include: a heater; a calibrated radiometer/calorimeter; a te

36、st headform; a set of temperature sensing elements and temperature indicator. The principle of a suitable apparatus is shown in Figure 1. 5.3.2 Heater A heater is mounted with its radiating surface horizontal and facing downwards. The radiating surface shall be flat with dimensions (250 5) mm by (25

37、0 5) mm. The peak wavelength of the emitted heat radiation shall be between 2 m and 3 m. The intensity of radiation shall be uniform and shall be adjustable. 5.3.3 Calibrated calorimeter/radiometer A calibrated (see notes) calorimeter/radiometer is mounted with its sensing surface horizontal and fac

38、ing upwards. It is free to move horizontally so that the centre of its sensing surface can be brought centrally underneath the heater. NOTE 1 The test equipment should be located away from surfaces which reflect the radiant heat which may fall on them or allow passage of measurable quantities of hea

39、t into the test equipment area. NOTE 2 The effects of draughts should be minimized. 5.3.4 Headform A headform, constructed of hardwood or of any material with an equivalent thermal conductivity and complying with EN 960:2006, shall be mounted on a movable and adjustable device. The test site shall b

40、e as specified in the helmet standard, corresponding to a nominal 30 lateral inclination of the headform relative to the vertical. NOTE All supports for headform and radiometer/calorimeter should be of low heat conductivity and reflectivity. 5.3.5 Temperature sensing elements Three calibrated (see n

41、otes) temperature sensing elements (each preferably consisting of a thermocouple mounted on a circular copper disc of (7 1) mm diameter) are secured by electrically insulating adhesive to the headform surface on the side to be exposed to the heat. EN 13087-10:2012 (E) DIN EN 13087-10:2012-046 Their

42、centres shall lie within 5 mm of the points defined by the intersection of a transverse vertical plane passing through the test site and: a) the central vertical axis; b) the AA plane (as defined in EN 960:2006, 2.4); c) midway between position a) and b) measured along the headform surface. NOTE Sui

43、table ISO or CEN standards should be selected, when available, for these calibration requirements. 5.4 Procedure 5.4.1 Mount the helmet on the headform in the manner it is intended to be worn on the head, with the test site lying centrally beneath the heater and measure the distance, d (see Figure 1

44、) from the radiating surface. Record the temperatures on the headform. 5.4.2 Move the helmeted headform aside to allow setting of the radiant heat intensity. 5.4.3 Move the radiometer/calorimeter centrally beneath the heater and adjust the distance, d (see Figure 1) from the radiating surface to cor

45、respond with that measured in 5.4.1. Adjust the heater controls until the heat flux intensity measured is as specified in the appropriate helmet standard. Remove the radiometer/calorimeter. 5.4.4 Replace the helmeted headform in the position determined in 5.4.1 and expose the helmet to the radiant h

46、eat for (180 2) s. At the end of this period, record the temperatures on the headform. 5.4.5 Switch off the heater and remove the helmet. Allow the helmet to cool to ambient temperature for at least 4 h before performing any further tests. 5.5 Report Report the maximum difference between the tempera

47、tures measured in 5.4.1 and 5.4.4.EN 13087-10:2012 (E) DIN EN 13087-10:2012-047 a) Measuring the radiant heat (5.4.3) b) Test set-up Key 1 heater 2 radiating surface 3 test site 4 helmet 5 headform 6 radiometer/calorimeter Figure 1 Schematic drawing for the radiant heat test EN 13087-10:2012 (E) DIN EN 13087-10:2012-048 Annex A (normative) Test results Uncertainty of measurement For each of the required measurements performe
