d) information relating to toxicological, allergenic, carcinogenic, toxic to reproduction or mutagenic investigations on the materials;
e) information relating to ecotoxicological and other environmental investigations on the materials.
The examination should determine whether the claim that the materials are suitable for use in the protective helmet is justified. Particular attention needs to be paid to the presence of plasticisers. unreacted components, heavy metals, impurities and the chemical identity of pigments and dyes.
All metallic materials which could come into prolonged contact with the skin (e.g. studs, fittings) shall have a release of Nickel of less than 0,5 pg/cm3 per week, when tested according to EN 1811.
Substances recommended for cleaning, maintenance or disinfection shall have no adverse effect on the helmet and shall be not known to be likely to have any adverse effect upon the wearer, when applied in accordance with the manufacturer’s instructions.
Materials shall conform to the relevant requirements of EN ISO 13688.
4.2 Projections
There shall be no sharp edges, roughness or projections on any part of the helmet, which are likely to cause injury to the wearer, in contact or potential contact with the wearer when the helmet is worn. Test according to
6.14.
4.3 Retention system
The helmet shall be fitted with a retention system, including a chinstrap. The chinstrap shall be adjustable in length.
4.4 Accessories and non-integral additional protective devices
When the helmet manufacturer states any accessories and/or non-integral additional protective devices, as defined in 3.7 and 3.8, as being for use with the helmet, the helmet with such items fitted to it shall continue to satisfy the requirements of this European Standard.
However, some accessories and/or non-integral additional protective devices may not be suitable for wildland fire fighting and only suitable for non-fire fighting associated activities such as wood cutting, road clearance. etc. In such cases, information shall be provided by the manufacturer as to the conditions under which such accessories and/or non-integral additional protective devices may be used.
If accessories and non-integral additional protective devices are supplied and/or recommended by the helmet manufacturer they shall individually conform to the requirements of the appropriate standard related to that specific device.
5.2.2 Lateral Impacts (front, side, rear)
When a helmet Is tested by the method described in 6.5.3. the force transmitted to the head form shall not exceed 5 kN, for an impact energy of (25 ± 1) J.
5.3 Penetration resistance
When a helmet is tested by the method described in 6.6, there shall be no contact between the striker and the
test block, for an impact energy of (30 ± 1) J.
5.4 Retention system effectiveness
When a helmet is tested by the method described in 6.7. the helmet shall not come completely off the head form.
5.5 Retention system strength
When a helmet Is tested by the method described in 6.8, the following shall apply:
a) Maximum dynamic elongation shall not exceed 25 mm under the intermediate load condition;
b) Minimum width of the chin strap under Intermediate load condition shall be 15 mm;
C) The release point of the retention system shall be between 500 N and 1 000 N.
5.6 Flame resistance
5.6.1 Helmet shell
When a helmet is tested by the method given in 6.9.1, any of the externally exposed materials of the helmet shell, not within 5 mm of an edge, shall not burn with the emission of flame or drip molten material after a period of 5s has elapsed from removal of the flame.
5.6.2 Retention system
Materials of the retention system that are outside of the helmet shell, when tested by the method given in 6.9.2, shall not bum with the emission of flame or drip molten material after a period of 5 s has elapsed from the removal of the flame.
5.6.3 Accessories and non-integral additional protective devices
Any items as defined in 3.7 and 3.8 stated as being for use with the helmet by the helmet manufacturer for wildland firefighting and associated operations and on the outside of the helmet shell.EN 16471-2014 pdf download.
