24、d performance requirements, methods of test and marking requirements for industrial bump caps. Industrial bump caps are intended to provide protection to the wearer against the effects of striking his head against hard, stationary objects with sufficient severity to cause laceration or other superfi
25、cial injuries. They are not intended to provide protection against the effects of falling or thrown objects, or moving or suspended loads. NOTE An industrial bump cap should not be confused with an industrial safety helmet, as specified in EN 397. 2 Normative references The following referenced docu
26、ments are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. EN 960:2006, Headforms for use in the testing of protective helmets ISO 6487:2

29、a means of maintaining the bump cap on the head. 3.3 harness 3.3.1 assembly complete assembly that may provide a means: a) of maintaining the bump cap in position on the head; b) of absorbing kinetic energy during an impact. NOTE A harness may include the items defined in 3.3.2, 3.3.3, 3.3.4 and 3.3
30、.5. DIN EN 812:2012-04 EN 812:2012 (E) 6 3.3.2 headband part of the harness, if fitted, completely or partly surrounding the head above the eyes at approximately the largest horizontal circumference of the head NOTE The headband may include a nape strap. 3.3.3 nape strap adjustable or self-adjusting
31、 strap that fits behind the head below the plane of the headband NOTE A nape strap may be an integral part of the headband, and may be elasticated. 3.3.4 cradle assembly of parts of the harness, if fitted, in contact with the head, excluding the headband and nape strap, if fitted NOTE The cradle may
32、 be either fixed or adjustable. 3.3.5 comfort band or sweatband accessory to cover at least the inner front surface of the headband, if fitted, to improve wearer comfort 3.4 ventilation holes holes provided in the shell, and/or external coverings, which can allow circulation of air inside the bump c
33、ap 3.5 chin strap strap which fits under the chin to help secure the bump cap on the head 3.6 chin strap anchorages means by which the material of the chin strap is attached to the bump cap NOTE This includes, for example: the component(s) fitted to the ends of the chin strap material for this purpo
34、se; that part of the bump cap shell or of the headband where the chin strap is attached. 3.7 bump cap accessories any additional parts for special purposes NOTE Examples of accessories are chin strap, neck protector, nape strap, external coverings. 3.8 wearing height vertical distance from the lower
35、 edge of the headband, if fitted, (or from the lower edge of the bump cap if there is no headband) to the highest point of the headform on which the bump cap is mounted, measured either at the front (midway between the sides of the headform) and at the side (midway between the front and back of the
36、headform) whichever gives the greater distance DIN EN 812:2012-04 EN 812:2012 (E) 7 4 Physical requirements 4.1 Materials and construction The bump cap may consist of a smooth shell, which may be enclosed by an outer covering. The bump cap shall incorporate means to absorb the energy of an impact. N
37、OTE Recommendations for materials and construction of bump caps are given in Annex A. For those parts of the bump cap that come into contact with the skin, materials which are known to be likely to cause skin irritation or any adverse effect on health shall not be used.
