25、lmets (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 prerequisites as the number of samples, preconditioning, preparation o

26、f 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. 1 Scope This European Standard describes methods of test for prote

27、ctive helmets. The purpose of these tests is to enable assessment of the performance of the helmet as specified in the appropriate helmet standard. This standard specifies the methods of test for flame resistance. 2 Normative references This European Standard incorporates, by dated or undated refere

28、nce, provisions from other publications. These normative references are cited at the appropriate places in the test and the publications are listed hereafter. For dated references, subsequent amendments to, or revisions of any of these publications apply to this European Standard only when incorpora

29、ted in it by amendment or revision. For undated references the latest edition of the publication referred to applies (including amendments). EN 13087-1 Protective helmets Test methods Part 1: Conditions and conditioning. 3 Terms and definitions For the purposes of this European Standard, the terms a

30、nd definitions found in the appropriate helmet standard apply. 4 Prerequisites In order to implement this European Standard, 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) seque

31、nce of conditioning; e) sequence of tests; f) duration of application of the flame; g) the test point(s).Page 5 EN 13087-7:2000 BSI 22 March 2002 5 Test methods 5.1 General Testing shall be performed in ambient conditions specified in EN 13087-1. 5.2 Principle The external surface of the helmet is e

32、xposed to a standard flame and the behaviour of the helmet is noted. 5.3 Apparatus The apparatus shall include: a) a supply of gas; b) a tap; c) a burner; d) a pressure control device; e) a manometer. The gas used shall be propane having a minimum purity of 95 %. The burner shall be suitable for pro

33、pane gas with a 10 mm diameter bore, an adjustable air vent and an appropriate size of jet. 5.4 Procedure Identify the test point. Open the tap of the gas supply and adjust the gas pressure to (3 450 50) Pa. Adjust the flame by means of the air vent so that the inner blue cone is clearly defined, al

34、though turbulent and is (45 5) mm long. There shall be no visible yellow colour in the outer envelope of the flame. Support the burner at an angle of (45 5) to the vertical, so that the flame points upward. Support the complete helmet, so that, at the point to be tested, the plane tangential to the

35、surface is horizontal (see Figure 1). Maintaining these angles, apply the outer part of the flame to the test point for a period as specified in the appropriate helmet standard. During this period, note the behaviour of the material(s) within the test area. At the end of this period, remove the flam

36、e and note the behaviour of the material(s) within the test area after a further (5 1) s. If the external surface of the helmet within the test area is made from more than one material, repeat this procedure so that each material is tested. 5.5 Report Report the behaviour of the material(s) within t

37、he test area, during the test and after removal of the flame.Page 6 EN 13087-7:2000 BSI 22 March 2002 Key 1 Helmet shell Figure 1 Schematic drawing of the flame testPage 7 EN 13087-7:2000 BSI 22 March 2002 Annex A (normative) Test results Uncertainty of measurement For each of the required measureme

38、nts performed in accordance with this standard, a corresponding 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. A
