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.
There shall be no sharp edge, roughness or projection on any part of the bump cap which is in
contact, or potential contact, with the wearer when the bump cap is worn, such as is likely to cause
injury to the wearer.
Any part of the bump cap which can be adjusted, or removed by the wearer for the purpose of
replacement, shall be so designed and manufactured as to facilitate adjustment, removal and
attachment without the use of tools.
Any adjustment system incorporated within the bump cap shall be so designed and manufactured as
not to become incorrectly adjusted without the wearer’s knowledge under the foreseeable conditions
of use.
4.2 Cradle
If the bump cap is fitted with a cradle incorporating textile tapes, their individual widths shall be not
less than 15 mm, and the total of the widths of the tapes radiating from their intersection shall be not
less than 72 mm.
NOTE Further reference to textile tapes is made in Annex A.

SIST EN 812:2012
EN 812:2012 (E)
4.6 Chin strap
Unless specific provision is made for the bump cap to be retained on the head by other means, the
bump cap or the harness shall be fitted with a chin strap or with means of attaching one. Any chin
strap supplied with the bump cap shall be not less than 10 mm wide when un-tensioned and shall be
attached either to the shell or to the headband, if fitted.
4.7 Ventilation
If the bump cap is provided with holes for ventilation purposes, the total area of such holes shall be
2 2
not less than 150 mm and not more than 450 mm .
NOTE 1 Means of closing the ventilation holes may be provided.
NOTE 2 If such means are provided, the holes should be opened to the maximum extent when the above
measurement is performed.
NOTE 3 Recommendations regarding design for ventilation are given in Annex A.
4.8 Accessories
For the fixing of bump cap accessories, specified in the information accompanying the bump cap in
accordance with 7.2.3, the required fixing devices, or appropriate holes in the bump cap, shall be
provided by the bump cap manufacturer.
5 Performance requirements
5.1 Mandatory requirements
5.1.1 Impact protection
When a bump cap is tested by the method given in 6.5, the force transmitted to the headform shall not
exceed 15,0 kN. This requirement shall be satisfied by bump caps treated in accordance with the
appropriate conditioning processes given in 6.2, as specified by the list of tests given in 6.1.
5.1.2 Resistance to penetration
When a bump cap is tested by the method given in 6.6, the point of the striker shall not contact the
surface of the headform. This requirement shall be satisfied by bump caps treated in accordance with
the appropriate conditioning processes given in 6.2, as specified by the list of tests given in 6.1.
5.1.3 Chin strap anchorages
When a bump cap is fitted with chin strap anchorages, these shall be tested in accordance with 6.7.
The artificial jaw shall be released at a force of not less than 150 N and not more than 250 N, due to
failure only of the anchorages.
5.2 Optional requirements
5.2.1 Very low temperature (–20 °C or –30 °C)
When tested for impact protection by the method given in 6.5, the requirement of 5.1.1 shall be
satisfied by one bump cap which has been conditioned in accordance with 6.2.
8
---------------------- Page: 10 ----------------------
SIST EN 812:2012
EN 812:2012 (E)
When tested for resistance to penetration by the method given in 6.6, the requirement of 5.1.2 shall
be satisfied by a second bump cap, which has been conditioned in accordance with 6.2.
Bump caps claimed to meet these requirements shall state this fact on the label attached to the bump
cap, in accordance with 7.2.2.
5.2.2 Resistance to flame
When tested by the method given in 6.8, the materials of the shell and/or external coverings shall not
burn with the emission of flame when a period of 5 s has elapsed after removal of the flame.
Bump caps claimed to meet this requirement shall state this fact on the label attached to the bump
cap, in accordance with 7.2.2.
5.2.3 Electrical properties
When tested by all three of the methods given in 6.9, the leakage current shall not exceed 1,2 mA.
NOTE 1 This requirement is intended to provide protection to the wearer against short term, accidental
contact with live electrical conductors at voltages up to 440 V (a.c.).
NOTE 2 Test 1 is intended to simulate closely the in-use situation, that is, the leakage current to the wearer
via a live conductor touching the shell.
NOTE 3 Test 2 is dependent only upon the transverse resistance of the complete shell (thickness). This
effectively precludes the use of a metal shell, and of metal fasteners or ventilation holes passing through the
shell.
NOTE 4 Test 3 is dependent only upon the surface resistance of the shell, and effectively precludes the use of
shells which have a conductive surface (e.g. metal electro-plating). This test was deemed to be necessary in
order to obviate the danger to the wearer should he try to remove a bump cap whose shell was in contact with a
live conductor.
Bump caps claimed to meet this requirement for all three tests shall state this fact on the label
attached to the bump cap, in accordance with 7.2.2.
6 Test requirements
6.1 Samples
Bump caps shall be submitted for testing in the condition in which they are offered for sale, including
any requisite holes and other means of attachment of any accessories specified by the bump cap
manufacturer.
No bump cap that has been subjected to testing shall be offered for sale.
The minimum number of samples and conditions required for one set of tests is as follows.
Mandatory tests:
1 bump cap for impact protection test at –10 °C;
1 bump cap for impact protection test, following water immersion;
1 bump cap for impact protection test at +50 °C;
1 bump cap for impact protection test, following artificial ageing;
1 bump cap for resistance to penetration test at –10 °C;
