EN 13087-2:2012 (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 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 13087-2:2012 (E) 5 1 Scope The 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 for determination of shock absorption. 2 Normative references The following referenced documents are indispensable for the application of this document. 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 ISO 6487, Road vehicles — Measurement techniques in impact tests — Instrumentation 3 Terms and definitions For the purposes of this document, the terms and definitions used in this standard can 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) sequence of conditioning; e) sequence of tests; f) method of test - 5.2 or 5.3; g) sizes of headforms; h) type of striker or anvil; i) fitting instructions; j) number and location of impact points on helmets; k) for each impact, the impact energy, including tolerance, of the falling mass for the falling mass method, or the impact speed, including tolerance, of the helmet/headform assembly for the falling headform method.

EN 13087-2:2012 (E) 6 5 Test methods 5.1 General Testing shall be performed in the 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 appropriate helmet standard. Two test methods are specified. The appropriate helmet standard will state which of these methods is applicable. Annex A refers to the uncertainty of measurement. 5.2 Falling mass method 5.2.1 Principle A specified striker is allowed to fall with specified energy on to a helmet which
