24、4 Introduction This European Standard is Part 1 of a standard containing requirements and test methods for motorcycle riders impact protectors. Impact protectors meeting the requirements of this European Standard will provide some protection against injury caused by impacts with road surfaces in mot
25、orcycle accidents. They may also slightly reduce the injuries caused by impacts with objects such as other vehicles. In order to encourage the adoption of certified protection by the highest possible number of users, two performance levels are specified for protectors. These are level 1 for protecto
26、rs designed to give protection whilst having low ergonomic penalties associated with its use and level 2 for protectors providing an increased protection with respect to level 1. There may be, however, weight and restriction penalties associated with level 2 protection. BS EN 1621-1:2012EN 1621-1:20

28、 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 340, Protective clothing General requirements EN ISO 105-E01, Tex

30、nt, the following terms and definitions apply. 3.1 zone of protection specific area of the protective equipment that is intended to provide protection to a part of the body and which is subject to specific testing 3.2 protector arrangement of energy absorbing and/or impact spreading materials design
31、ed to offer some protection to the zones of protection 3.3 type A protector protectors of smaller dimension; these are more commonly (although not exclusively) optimised for use with smaller riders 3.4 type B protector protectors of larger dimension; these are more commonly (although not exclusively
32、) optimised for use with larger riders 3.5 test area area on which impact tests are performed; size and shape are defined by the template 3.6 template auxiliary tool made of flexible material used to verify the minimum area of protection BS EN 1621-1:2012EN 1621-1:2012 (E) 6 4 Zones of protection an
33、d protectors The following body regions are specified as zones of protection and protectors shall be categorised as follows: a) shoulder: protector “S”; b) elbow and forearm: protector “E”; c) hip: protector “H”; d) knee and upper tibia: protector “K”; e) knee, upper and middle tibia: protector “K +
34、 L”; f) leg below protector “K”: protector “L”. The size of the zones of protection shall comply with 5.3, Table 1. 5 Requirements 5.1 General Unless otherwise specified, all linear dimensions bigger than 50 mm in the whole text shall be provided with a deviation of 2 % and dimensions up to 50 mm wi
35、th a deviation of 1 mm. Limb joint protectors shall be provided with means of restraint capable of ensuring that the protector is maintained in position during use. This requirement is not applicable for protectors to be inserted or incorporated into the garments. Testing shall be carried out accord
36、ing to 6.4. 5.2 Innocuousness 5.2.1 The materials shall comply with the requirements for innocuousness of materials in EN 340, with the exception of the requirement concerning the colour fastness to perspiration which is replaced by 5.2.2. 5.2.2 The colour fastness to water of the constituent materi
37、als which could be likely to come into contact with the skin of the user shall be determined in accordance with 6.2 and shall be at least grade 4 of the Grey scale for the staining of any component of the multi-fibre reference fabric. 5.3 Minimum dimensions of zone of protection Motorcyclists limb j
38、oint protectors shall provide a zone of protection with the minimum dimensions as specified in Table 1. Testing shall be carried out as described in 6.3.4. In Table 1, the zones of protection are defined by the three dimensions r1, r2 and l, as illustrated in Figure1: BS EN 1621-1:2012EN 1621-1:2012

40、 24 185 70 30 240 5.4 Impact attenuation In terms of impact attenuation, this standard includes two performance levels. The degree of risk or hazards that a motorcyclist faces is closely linked to the type of riding and the nature of the accident. Level 1 performance is deemed as the minimum level r
41、equired so that the protector provides useful protection in an accident and offers the protector with an optimum comfort level to suit all riding types. Where riders feel that their riding style exposes them to an increased accident risk, Level 2 has been provided, which offers increased performance
42、. Level 2 may have an increased penalty for the weight and comfort. When impact protection is tested in accordance with 6.3.4.2 (ambient impact test), 6.3.4.3 (wet impact test after hydrolytic ageing) and, if required, 6.3.4.4 (high temperature impact test) and/or 6.3.4.5 (low temperature impact tes
43、t), the transmitted force shall conform to the values in Table 2. Level 1 or Level 2 can only be awarded provided that such level is achieved under all test conditions claimed.

BS EN 1621-1:2012EN 1621-1:2012 (E) 8 After each test, there shall be no fragmentation of the sample and no sharp edges shall be formed. However, formation of cracks and loss of soft debris is perm
45、issible. 5.5 Ergonomic requirements When examined and tested in accordance with 6.4, impact protectors shall be found satisfactory for the use intended; to confirm this requirement, each question of 6.5 needs to be answered with “yes”. The following deficiencies are not admitted: a) sharp edges; b)
46、any design feature which cause ergonomic problems to the assessor (see 6.4). 6 Test methods and equipment 6.1 General For each of the required sequences of measurements performed in accordance with this standard a corresponding estimate of the uncertainty of the final result shall be determined. On
47、request, this uncertainty (Um) shall be given in the test report in the form Um = X. It shall be used in determining whether a “Pass” performance has been achieved. If the final result plus Um is above the maximum Pass level, the sample shall be deemed to have failed. Measuring instruments or their
48、independent working components unless otherwise specified shall have an error limit of 4 % of the pass/fail level of the characteristic being measured. In the following subclauses both testing methods and equipment are described. 6.2 Innocuousness For colour fastness to water, materials of protectiv
49、e clothing shall be tested according to EN ISO 105-E01 for textiles and according to EN ISO 11642 for leather. 6.3 Impact attenuation 6.3.1 Equipment 6.3.1.1 Dropping apparatus The apparatus shall be such that a falling mass (“drop striker”) may be released in order to drop along a guided vertical path with an energy of (50 2) J onto the sample placed on a test anvil. The centre axis of the falling mass coincides with the centre axis of the anvil. 6.3.1.2 Drop striker The drop striker shall
