This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorse

15、ment, at the latest by August 2013, and conflicting national standards shall be withdrawn at the latest by August 2013. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for identifyi

16、ng any or all such patent rights. This document supersedes EN 1080:1997. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of EU Directive(s). For relationship with EU Directive(s), see

17、 informative Annex ZA, which is an integral part of this document. The significant technical changes that have been made since the previous version of this standard are described in Annex A. According to the CEN/CENELEC Internal Regulations, the national standards organisations of the following coun

18、tries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Po

BS EN 1080:2013EN 1080:2013 (E) 4 Introduction This European Standard specifies requirements and test methods for helmets intended for use by young children while pursuing recreational activities

20、in environments which have proven risks of head injuries in combination with risk of strangulation. The helmet itself is not intended to be worn at play in the playground or while using playground equipment. Head protection in these areas is covered by standards for design of playground equipment an

21、d surfaces. Since there is a foreseeable risk of being trapped by the helmet, these helmets are equipped with a self-release mechanism to minimise the risk. This standard does not replace other standards for head protection. Helmets according to this standard do offer shock absorption performance of

22、 the same value as i.e. helmets for pedal cyclists or skiers. However, they do not meet all other requirements which these helmets fulfil, for example strength of retention system or penetration for skiing helmets. The protection given by a helmet depends on the circumstances of the accident and wea

23、ring a helmet cannot always prevent death or long term disability. A proportion of the energy of an impact is absorbed by the helmet, thereby reducing the force of the blow sustained by the head. The structure of the helmet may be damaged in absorbing this energy and any helmet that sustains a sever

24、e blow needs to be replaced even if damage is not apparent. The Technical Committee which has prepared this standard realises that it is of importance for the wearers comfort and psychometric performance that a helmet is ventilated. At the time this European Standard was prepared, no method for meas

25、uring the ventilating capacity of a helmet was recognised. For that reason, no requirements concerning ventilation or heat transmission have been introduced. BS EN 1080:2013EN 1080:2013 (E) 5 1 Scope This European Standard specifies requirements and test methods for helmets intended for use by young

26、 children while pursuing recreational activities in environments which have proven risks of head injuries in combination with risk of strangulation. Requirements and the corresponding methods of test are given for the following: construction including field of vision; shock absorbing properties; ret

27、ention system properties, including chin strap, fastening devices and self-release system; marking and information. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

30、apply. 3.1 protective helmet item to be worn on the head and intended to absorb the energy of an impact thus reducing the risk of injury to the head 3.2 helmet type category of helmets which does not differ in such essential respects as the materials or dimensions of the helmet shell, the constructi

31、on of the helmet, the retention system or the protective padding Note1 to entry: Helmet type may include a range of helmet sizes, provided that the helmet shell, including the protective padding, is the same. 3.3 padding BS EN 1080:2013EN 1080:2013 (E) 6 3.3.1 protective padding material used to abs

32、orb impact energy 3.3.2 comfort padding lining material provided for the wearers comfort 3.3.3 sizing padding lining material used for adjustment of the helmet size 3.4 retention system complete assembly by means of which the helmet is maintained in position on the head including any devices for adj

33、ustment of the system or to enhance the wearers comfort 3.5 chin-strap part of the retention system consisting of a strap that passes under the wearers jaw to keep the helmet in position 3.6 self-release system mechanism which releases when loaded with a certain force 3.7 basic plane for a given hea

34、dform, horizontal plane located at a vertical distance x below and parallel to the reference plane Note1 to entry: This corresponds to the basic plane of the human head being the longitudinal plane which passes through the lower level of the eye orbits and the upper level of the external opening of

35、the ear canals. 3.8 reference plane for a given headform, when erect, horizontal plane located at a vertical distance y measured down the central vertical axis from the centre of the crown Note1 to entry: All horizontal datum levels are quoted relative to this plane. 3.9 test area area of the helmet

36、 in which impact tests may be conducted which corresponds to the minimum protected area of the human head 4 Requirements 4.1 Materials For those parts of the helmet coming into contact with the skin, the material used shall not be subject to any known appreciable alteration from contact with sweat o

37、r with substances likely to be found in toiletries. Materials shall not be used which are known to cause skin disorders or other adverse effects on health. For a material not in general use, advice as to its suitability shall be sought before its introduction. BS EN 1080:2013EN 1080:2013 (E) 7 Examp

38、les for documents which can be presented as evidence of chemical innocuousness are given in the note. NOTE The following list of documents is given for information and as examples of documents to be examined: a) materials specifications; b) safety data sheets relating to the materials; c) informatio

39、n relating to the suitability of the materials for use with food, in medical devices, or other relevant applications; d) information relating to toxicological, allergenic, carcinogenic, toxic to reproduction or mutagenic investigations on the materials; e) information relating to ecotoxicological an

40、d other environmental investigations on the materials. The examination shall determine whether the claim that the materials are suitable for use in the protective helmet is justified. Particular attention needs to be paid to the presence of plasticisers, unreacted components, heavy metals, impuritie

41、s and the chemical identity of pigments and dyes. All metallic materials which could come into prolonged contact with the skin (e.g. buckles, studs, fittings) shall have an emission of nickel of less than 0,5 g/cm per week. The method of test shall be according to EN 1811. 4.2 Construction The helme

42、t normally consists of a means of absorbing impact energy, a means of retaining the helmet on the head and a self-release system. The helmet shall be so designed and shaped that in normal use the parts of it in contact or in potential contact with the user shall be free of roughness, sharp edges, pr

43、ojections and anything which could be harmful to the user. Helmets should: have low weight; be ventilating; be easy to put on and take off; be usable with spectacles; not significantly interfere with the ability of the user to hear traffic noise. 4.3 Field of vision When tested according to 5.6, the

44、re shall be no occultation in the field of vision bounded by angles as follows (see Figure 1): horizontally: min 105 from the longitudinal vertical median plane to the left and right hand sides; upwards: min 25 from the reference plane; downwards: min 45 from the basic plane.
