21、art 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 me

22、ans that the protection efficiency is as high as possible, without decreasing the wearers 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 reducin

23、g 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 h

24、elmet 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. BS EN 13484:2012 EN 13484:2012 (E) 6 1 Scope This European Standard specifies the minimum performance requiremen
