This European Standard shall be given the status of a national
18、 standard, either by publication of an identical text or by endorsement, at the latest by June 2015 and conflicting national standards shall be withdrawn at the latest by June 2015. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights.
19、CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights. 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 wi
20、th EU Directive(s), see informative Annex ZA, which is an integral part of this document. The purpose of this European Standard is to provide minimum performance requirements for helmets designed for use for extended periods during wildland fire fighting and associated activities. Wildland fire figh
21、ting involves work primarily in summer temperatures, for many hours during which the fire fighter may develop high levels of metabolic heat. Consequently, the protective helmet should be comfortable, light and commensurate with the risks to which the fire fighter may be exposed in order to be effect
22、ive without introducing heat stress to the wearer. This European Standard does not cover helmets for use in situations where helmets conforming to EN 443 are more suitable. According to the CEN-CENELEC Internal Regulations, the national standards organizations of the following countries are bound to
23、 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, Poland, Portugal, Ro
24、mania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom. BS EN 16471:2014EN 16471:2014 (E) 5 1 Scope This European Standard specifies the minimum requirements for wildland fire fighting helmets protecting the upper head mainly against the effects of impact, penetration,
25、heat, flame and burning embers while conducting fire fighting and associated activities in wildland environments. Requirements for marking and information to be supplied by the manufacturer are included. Wildland fire fighting involves direct and indirect attack techniques (like wood cutting). Wildl
26、and environments include forests, crops, plantations and grass/heath/scrub or farmland. Helmets for use while fire fighting in buildings and other structures are not covered by this European Standard (see EN 443). This helmet is not intended to provide protection during fire entrapment. Protection o
27、f the face, eyes, ears and neck may require additional items of personal protective equipment (PPE), which are not covered by this European Standard. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its applica

33、s apply. 3.1 helmet for wildland fire fighting headwear, including all integral components supplied by the manufacturer, intended primarily to protect the upper part of a wearers head against hazards which may occur during wildland fire fighting activities Note 1 to entry: Hereafter, helmets for wil
34、dland fire fighting are referred to as helmets. 3.2 helmet shell component in hard material with a smooth finish, which gives the helmet its general shape 3.3 protective padding material and/or suspension system which serves to dampen impact energy 3.4 retention system those parts which are responsi
35、ble for securing the helmet in position on the head, including items which enable adjustment or improved comfort 3.5 chin strap part of a retention system, including a strap which passes under or on the wearers chin and which helps to ensure that the helmet is correctly maintained in place 3.6 head
36、form shape replacing the head which is used for testing certain characteristics Note 1 to entry: The head form is designed in accordance with EN 960. 3.7 accessories additional device(s) supplied or recommended by the manufacturer which may be attached to the helmet but which provide no protective f
37、unction to the wearer EXAMPLES Lamp brackets, cable clips, badges and trims. 3.8 non-integral additional protective devices additional protective device(s) supplied or recommended by the manufacturer which may be attached to the helmet and intended to be removable by the user EXAMPLES Mesh visors, e
38、ar defenders, neck-guard and safety goggles. 4 Physical requirements 4.1 Materials For those parts of the helmet coming, or that may come, into contact with the skin the material used shall not be subject to any known appreciable alteration from contact with sweat or with substances likely to be fou
39、nd in toiletries. Materials shall not be used which are known to cause skin disorders or other adverse effects on health. BS EN 16471:2014EN 16471:2014 (E) 7 Examples of documents, which can be presented as evidence of chemical innocuousness, are given in the note. NOTE The following list of documen
40、ts is given for information and as examples of documents to be examined: a) materials specifications; b) safety data sheets relating to the materials; c) information relating to the suitability of the materials for use with food, in medical devices, or other relevant applications; d) information rel
41、ating to toxicological, allergenic, carcinogenic, toxic to reproduction or mutagenic investigations on the materials; e) information relating to ecotoxicological and other environmental investigations on the materials. The examination should determine whether the claim that the materials are suitabl
42、e for use in the protective helmet is justified. Particular attention needs to be paid to the presence of plasticisers, unreacted components, heavy metals, impurities and the chemical identity of pigments and dyes. All metallic materials which could come into prolonged contact with the skin (e.g. st
43、uds, fittings) shall have a release of Nickel of less than 0,5 g/cm3per week, when tested according to EN 1811. Substances recommended for cleaning, maintenance or disinfection shall have no adverse effect on the helmet and shall be not known to be likely to have any adverse effect upon the wearer,
44、when applied in accordance with the manufacturers instructions. Materials shall conform to the relevant requirements of EN ISO 13688. 4.2 Projections There shall be no sharp edges, roughness or projections on any part of the helmet, which are likely to cause injury to the wearer, in contact or poten
45、tial contact with the wearer when the helmet is worn. Test according to 6.14. 4.3 Retention system The helmet shall be fitted with a retention system, including a chinstrap. The chinstrap shall be adjustable in length. 4.4 Accessories and non-integral additional protective devices When the helmet ma
46、nufacturer states any accessories and/or non-integral additional protective devices, as defined in 3.7 and 3.8, as being for use with the helmet, the helmet with such items fitted to it shall continue to satisfy the requirements of this European Standard. However, some accessories and/or non-integra
47、l additional protective devices may not be suitable for wildland fire fighting and only suitable for non-fire fighting associated activities such as wood cutting, road clearance, etc. In such cases, information shall be provided by the manufacturer as to the conditions under which such accessories a
48、nd/or non-integral additional protective devices may be used. If accessories and non-integral additional protective devices are supplied and/or recommended by the helmet manufacturer they shall individually conform to the requirements of the appropriate standard related to that specific device.
