25、2+A1:2012 (E) 5 Introduction Advances in materials and design methods have allowed helmets to be developed that have a higher performance than other types of general industrial helmets. Helmets complying with European Standards offer a suite of head protection devices for general industrial use: the

26、 industrial bump cap meeting the requirements of EN 812, the industrial safety helmet meeting the requirements of EN 397, and the high performance industrial helmet meeting the requirements of EN 14052. Industrial bump caps are intended to provide protection to the wearer against the effects of stri

27、king his head against hard, stationary objects with sufficient severity to cause lacerations or other superficial injuries. They are not intended to provide protection against the effects of falling or thrown objects, or moving or suspended loads. In addition to the mandatory requirements the caps m

28、ay have shock absorption properties at low temperatures, be flame resistant and have electrical properties. Industrial safety helmets are intended primarily to provide protection to the wearer against falling objects and are not intended to provide protection against off crown impacts. The mandatory

29、 requirements for the helmets includes for them to have flame resistant properties. In addition to the mandatory requirements the helmets may have shock absorption properties at very low temperatures and very high temperatures, have electrical insulation properties, have lateral deformation properti

30、es, and provide protection against molten metal splash. The high performance industrial helmet offers greater protection from falling objects, protection from off crown impacts and protection from penetration by a flat blade striker. It also includes a retention system that meets mandatory requireme

31、nts for system release and system effectiveness properties. The helmet has the same flame resistant properties as the industrial safety helmet and offers the same optional protection against other risks with the exception of lateral deformation. The technical committee, which has prepared this Europ

32、ean Standard, realizes that mechanical rigidity is of importance for the wearers safety. At the time, the standard was prepared no valid test method was recognized. For that reason, no requirements concerning mechanical rigidity have been introduced. Designers are encouraged to accommodate ear, eye,

33、 and respiratory protection into the helmet design where required. When possible the design and performance of such additional protective functions should be in accordance with the relevant European Standard for these products. When this is not possible, the manufacturer will draw attention to any c

34、ompromises by means of information supplied with the helmet. The wearing of a helmet meeting the requirements of this European Standard will reduce, but not eliminate, the likelihood of head injury. There are limits to the amount of protection that can be provided. In the workplace, it remains the r

35、esponsibility of the employer to judge the helmets suitability for their particular purpose. BS EN 14052:2012+A1:2012EN 14052:2012+A1:2012 (E)EN 14052:2012+A1:2012 (E) 6 1 Scope This European Standard specifies physical, performance, test and marking requirements for high performance industrial helm

36、ets. High performance industrial helmets, as specified in this European Standard, are intended to provide to the wearer protection against falling objects and off crown impacts and the consequential brain injury, skull fracture and neck injury. This European Standard includes mandatory requirements

37、that apply to all high performance industrial helmets and additional, optional, performance requirements that apply only where specifically claimed by the helmet manufacturer. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are ind
