EN 13484:2012 (E) 5 Introduction The intention of helmets is to reduce the risk of injury to the skull and part of the head surrounded by the helmet. The protection given by a helmet depends on the circumstances of the accident and wearing a helmet cannot always prevent death or long term disability. In this European Standard, the concept of optimum level of protection has been taken into account. This means that the protection efficiency is as high as possible, without decreasing the wearer’s acceptance to the extent that she/he will not wear it, because of discomfort caused by the increase of the mass and dimensions. 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 can be damaged in absorbing this energy and any helmet that sustains a severe blow should be replaced even if damage is not apparent. To achieve the performance of which it is capable, and to ensure stability on the head, a helmet should be as closely fitting as possible consistent with comfort. In use it is essential that the helmet is securely fastened, with any chin strap under proper tension at all times. SIST EN 13484:2012

EN 13484:2012 (E) 8 4 Requirements 4.1 Materials For those parts of the helmet coming into contact with the skin the material used shall be known not to undergo appreciable alteration from contact with sweat or with substances likely to be found in cosmetic products. Materials shall not be used which are known to cause skin disorders. Testing according to 5.1. 4.2 Construction 4.2.1 General The helmet normally consists of means of absorbing impact energy and means of retaining the helmet on the head even in an accident. The helmet shall be so designed and shaped that parts of it (visor, rivets, ventilators, edges, fastening device and the like) are not likely to injure the user in normal use. NOTE Helmets should:  have low weight;  be easy to put on and take off;  be usable with spectacles;  not significantly interfere with the ability of the user to hear;  have good durability and withstand normal handling;  permit cleaning. Testing shall be in accordance with 5.1. 4.2.2 Retention system 4.2.2.1 General Means shall be provided for retaining the helmet on the wearer's head. All parts of the retention system shall be securely attached to the system or to the helmet. NOTE 1 It is recommended that the opening mechanism be marked with red or orange colour. NOTE 2 The colour of any part of the retention system should not be green, as green is used for helmets with an emergency release system. Testing shall be in accordance with 5.1. 4.2.2.2 Chin straps The chin strap shall not include a chin cup. Any chin strap shall be no less than 15 mm wide. Chin straps can be fitted with means of enhancing comfort for the wearer. SIST EN 13484:2012
