This method or other 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 s

If deviations from the test method given in this standard are necessary, these deviations will be specified in the appr

21、opriate helmet standard. BS EN 13087-6:2012EN 13087-6:2012 (E) 5 1 Scope This European Standard specifies test methods 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 s

22、pecifies the test method for field of vision. 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 o

23、f the referenced document (including any 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 used

24、in this standard may be found in the appropriate helmet standard. 4 Prerequisites In order to implement this part of EN 13087, at least the following parameters need to be specified in the appropriate helmet standard: a) performance requirements; b) number of samples; c) preparation of samples; d) s

25、equence of conditioning; e) sequence of tests; f) sizes of the headforms. 5 Methods 5.1 General Testing shall be performed in ambient conditions specified in EN 13087-1. When the test method specifies that the helmet shall be fitted to a headform, this shall be done in accordance with the manufactur

26、ers fitting instructions, if supplied. If none are supplied, the helmet shall be fitted so as to simulate typical in-use fitting. BS EN 13087-6:2012EN 13087-6:2012 (E) 6 5.2 Principle The helmet is placed on a test headform and the field of vision is measured by reference to markings on the headform

27、. 5.3 Apparatus The apparatus shall include: a) a series of test headforms in accordance with EN 960:2006; b) a ballast mass of (5,0 + 0,5) kg; c) a series of angle templates or other means of assessing angles of vision. 5.4 Procedure The size(s) of headform to be used is specified in the helmet sta

28、ndard. The test headform(s) to be used shall be marked with: a) the following planes as defined in EN 960:2006 and in Figure 1 of this European Standard respectively: basic plane; reference plane; vertical transverse plane (defined in EN 960:2006, 2.9 as mid-way between the headforms front and rear

29、extremities); vertical longitudinal plane (defined in EN 960:2006, 2.8 as mid-way between the headforms left- and right-hand extremities). b) points K1, K2, L1, L2 as defined in Figure 1 of this European Standard. Place the helmet on the headform. Place the ballast mass on the crown of the helmet in

30、 order to stabilize it in position. Ensure that the vertical longitudinal plane of the helmet coincides with the vertical longitudinal plane of the headform. Adjust the helmet on the headform in accordance with the manufacturers instructions, if supplied. If they are not supplied, adjust the helmet

31、to simulate typical in-use fitting. Once positioned, assess, using the angle templates or other means, whether the requirements for no occultation are satisfied for the horizontal directions from points L1 and L2 and for the vertical directions, upwards from points L1 and L2, and downwards from poin

32、ts K1 and K2. 5.5 Report Report whether occultation occurs in the specified field of vision.

34、estimate of the uncertainty of measurement shall be evaluated. This estimate of uncertainty shall be applied and stated when reporting test results, in order to enable the user of the test report to assess the reliability of the data.
