EN 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 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 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 13781:2012

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 helmet 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 the 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 permanently 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 There 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.

EN 13781:2012 (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 protective 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′ 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 wearer's head by means of a retention system which is secured under the lower jaw. All parts of the retention system shall be permanently 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 The device to open the retention system shall not be capable of opening other than as a result of a deliberate act. In the case of a press-fastener opening device, the press-fastener shall be recessed, the surface to which the pressure is applied shall be fitted with a fairing about its whole periphery so that opening does not occur when the surface is pressed with a sphere of 100 mm diameter. Testing shall be in accordance with 5.1. 4.4.4 If a retention system includes a quick-release mechanism, then the method of release of this mechanism shall be self-evident. Any levers, tabs, buttons or other components which need to be operated to release the mechanism shall be coloured red, those parts of the rest of the system which are visible when closed shall not be similarly coloured, and the mode of operation shall be permanently indicated. Testing in accordance with 5.1. 4.4.5 The retention of the helmet on the head by the retention system shall be verified in accordance with 5.6. When a helmet type includes a range of sizes, the helmet subjected to the test shall be that presenting the least favourable conditions (such as the thickest padding). 4.5 Materials 4.5.1 The characteristics of the materials used in the manufacture of helmets shall be known not to undergo appreciable alteration under the influence of ageing or of the circumstances of use to which the helmet is normally subjected, such as exposure to sun, extremes of temperature and rain. For those parts of the helmet coming into contact with the skin, the materials used shall be known not to undergo appreciable alteration through the effect of perspiration or of toilet preparations. The manufacturer shall not use materials known to cause skin troubles. The suitability of a proposed new material shall be established by the manufacturer. 4.5.2 After the performance of one of the prescribed tests, the protective helmet shall not break or deform in a way which is dangerous to the wearer.
