EN 13087-5:2012 (E) 4 Introduction This European Standard is intended as a supplement to the specific product standards for protective helmets (helmet standards). This method or other test methods may be applicable to specified 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, preconditioning, 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 13087-5:2012 (E) 5 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 retention system strength. 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 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, terms and definitions given 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 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 tests; f) method of test - 5.2 (including 5.2.3.1 or 5.2.3.2), 5.3 or 5.4, and the initial and intermediate forces; g) sizes of the headforms; h) impact energy, including tolerance, of the falling mass - methods 5.3 and 5.4; i) fitting instructions. 5 Methods 5.1 General Testing shall be performed in ambient conditions specified in EN 13087-1. Three test methods are specified. The method to be used is specified in the helmet standard. SIST EN 13087-5:2012

EN 13087-5:2012 (E) 6 5.2 Headform support, increasing load method 5.2.1 Principle The helmet is supported on a headform and a specified, varying force is applied to the retention system via an artificial jaw. In method (a) (see 5.2.3.1) the ultimate tensile strength of the system alone is measured. In method (b) (see 5.2.3.2) the elongation of the system is measured as well. 5.2.2 Apparatus 5.2.2.1 General The apparatus shall include:  a series of headforms;  a rigid structure to support the headforms;  an artificial jaw;  a means of applying a variable tensile force to the artificial jaw;  a means to measure the displacement of the artificial jaw. An arrangement of a suitable apparatus is shown in Figure 1. 5.2.2.2 Test headforms Headforms, conforming to EN 960:2006, 2.2, 3.1.2 and 3.2. The sizes to be used are specified in the helmet standard, but shall be selected from size designations 495, 535, 575, 605 and 625 (equivalent to codes A, E, J, M and O, respectively, EN 960:1994). 5.2.2.3 Rigid structure Rigid structure, capable of supporting the headform so that it does not move during the test. 5.2.2.4 Artificial jaw Artificial jaw, comprising two rigid cylindrical rollers of diameter (12,5 ± 0,5) mm, with their longitudinal axes separated by (75 ± 2) mm. 5.2.2.5 Means of applying a known variable force to the artificial jaw Any suitable means may be used. 5.2.2.6 Means to meas
