7.3.1.1.3 Headforms and Ioadbearing device
The headforms to be used shall comply with EN 960:2006.
The loadbeanng device with the guide and arrest device shall be aligned with the vertical axis passing through the centre of gravity of the headform.
The mass of the headform equipped with the loadbearing device shall be (15± 0.5) kg, which shall be the preloading on the retention system for determining the position from which the vertical displacement of the point of application of the force shall be measured. The guide and arrest device shall allow a weight with a mass of (10± 0,1) kg to drop in a guided free fall (300 ± 5) mm.
7.3.1.1.4 Measuring device
A device to measure the vertical displacement of the point of application of the force.
7.3.1.2 Procedure
For each type of helmet take two helmets of each size that have just undergone the shock absorption test, one of which shall have been UV-conditioned, the other sample determined by the testing authority.
Position the helmet as prescribed in Annex A.
In this position, the helmet shall be held by the shell by means of the helmet support at a point traversed by the vertical axis passing through the centre of gravity of the headform.
Release the drop weight and allow it to drop from a height of (300 ± 5) mm.
During the test measure the dynamic displacement of the point of application of the force.
After 2 mm measure the residual displacement of the point of application of the force.
7.3.2 Determination of retention system effectiveness
The helmet shall be fitted to the appropriate headfocm which should be the smallest claimed for that helmet type.
A device (the total mass being (3,0 ± 0.1) kg) to release a falling weight is hooked onto the rear part of the shell in the median vertical plane of the helmet, as shown in Figure 4.
The falling weight, the mass of which shall be (10 ± 0,01) kg, is then released and drops In a guided free fall from a height of (250 ± 10) mm. The guiding devices shall be such as to ensure that the impact speed is not less than 95 % of the theoretical speed.
7.4 Determination of field of vision
To carry out the test, the testing laboratory shall select the size it considers likely to yield the least favourable result for the helmet type.
Position the helmet on a headforrn corresponding to its size by the procedure prescribed in Annex A. Check the field of vision according to Annex C.
7.5 Test report
The test report shall contain at least the following information:
a) identification details of the helmets tested including range of sizes:
b) results of the tests in accordance with 7.2, 7.3 and 7.4:
C) date of testing;
d) name of the testing laboratory.
8 Marking
Each helmet shall be marked in such a way that the following information is easily legible by the user and is likely to remain legible throughout the life of the helmet:
— the number of this European Standard:
— the name or trademark of the manufacturer;
— the designation of the model;
the code letters for the helmet category (see Clause 1):
the size or size range of the helmet, quoted as the circumference in centimetres of the head which the helmet is intended to fit (the marking of the size may differ from the size determined by the test authority by a maximum of 1 cm):
— the mass of the helmet to the nearest 50 g; year and quarter of manufacture.
warning (If appropriate): The helmet shall only be used in combination with the attachment(s).
In addition, if the shell is made of a material which is known to be adversely affected by contact with hydrocarbons, cleaning fluids, paints, transfers or other extraneous additions, the helmet shall carry an appropriate warning.
9 Information for users
With every helmet distinct information in the language of the country of sale shall be furnished as follows:
— that the helmet shall be adjusted to fit the user;
how the helmet should rest on the head to ensure the intended protection (e.g. that it should be placed so as to protect the forehead and not be pushed too far back over the back of the head);
— that a helmet subjected to violent impact shall be discarded:
— an explanation of the code letters used for the relevant category of helmets for airborne sports (HPG: Helmets for paraglidirig and hang gliding: UL: Helmets for flying with ultra-light aeroplanes):
— a detailed explanation how and by which attachments the assembly needs to be completed for proper use of the helmet, if the helmet is designed to form an integral assembly with accessories.EN 966-2012 pdf download.
