21、13781:2012EN 13781:2012 (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
22、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 severe blow should be replaced even if damage is not apparen
23、t. 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. BS EN 13781:2012EN

40、a retention system. The helmet usually has also connection systems for accessories. 4.1.2 The helmet may be fitted with accessories such as a communication system, hearing protectors, eye protectors, face shield or a lower face cover. It may also have a detachable peak. 4.1.3 The design of the helme
41、t shall be such that the temperature in the space between the head and the helmet does not rise or decrease inordinately. Ventilation holes or other means may be provided in the shell. 4.1.4 The outer surface of the shell shall be perfectly smooth. Above the reference plane, the shape shall be in th
42、e form of a continuous convex curve, except where shaping is provided for functional purposes. Below the reference plane, irregularities in the curve shall be smoothly faired. The shell shall not incorporate an integral peak but may incorporate an integral lower face cover. 4.1.5 There shall be no p
43、ermanently fixed external projections greater than 5 mm above the outer surface of the shell. Any external projections other than press-fasteners shall be smooth and adequately faired. Rivet heads shall be radiused and shall not project more than 2 mm above the outer surfaces of the shell. 4.1.6 The
44、re shall be no inward-facing sharp edges on the inside of the helmet. 4.1.7 The integrated components of the helmet which are intended to protect the head of the user shall be assembled such that they shall not become easily detached or move when tested in accordance with 5.1.

45、81:2012 (E) 9 4.1.8 Where means for attaching eye protectors are not provided, the profile at the front edge shall not prevent the wearing of goggles. Testing shall be in accordance with 5.1. 4.2 Compatibility with additional devices No component or device may be fitted to or incorporated in the pro
46、tective helmet unless it is designed in such a way that it will not cause injury. When the component or device is fitted to or incorporated in the helmet, the helmet shall still comply with the requirements of this European Standard. 4.3 Protected area The shell shall cover all areas above plane AA
47、in Figure 1, and shall extend downwards at least as far as the lines CDEF on both sides of the headform. 4.4 Retention system 4.4.1 The helmet shall be held in place on the wearers head by means of a retention system which is secured under the lower jaw. All parts of the retention system shall be pe
48、rmanently attached to the system or to the helmet. Testing shall be in accordance with 5.1. 4.4.2 If the retention system includes a chin strap the strap shall be no less than 20 mm wide under a load of (150 5) N applied in accordance with 5.6.2. The chin strap shall not include a chin cup. 4.4.3 Th
