Introduction
This document specifies the requirements for protective headwear for use by young children while
pursuing recreational activities, such as cycling, roller-sports and sledging, in environments which have
risks of head injuries in combination with risk of strangulation.
The requirements in this document are concerned with the performance of a helmet to reduce the risk of
injury to the skull, brain and part of the head within the specified area of protection. Performance levels
and test methods are based upon proven methods of test and technical criteria and enhanced by data
from expert sources in the field of head protection. A unique feature of this standard is the requirement
on a self-release mechanism to minimize the risk for children to be hanged in the chin strap of a helmet.
The risk arises when the child combines the intended activity with playing. This is a well-known risk,
there have been at least 9 known cases in Europe with fatal outcomes where children have been strangled
by traditional chin straps. The release properties in the standard have been designed for release at
entrapment, and based on scientific investigations on chin strap forces, to ensure that the helmet is not
released in case of a severe cycle accident.
The helmet itself is not intended to be worn at play in the playground or while using playground
equipment, head protection in these areas is covered by standards for design of playground equipment
and surfaces.
This standard does not replace other standards for head protection. Helmets according to this standard
do offer shock absorption performance of the same value as i.e. helmets for cyclists or skiers. However,
they do not meet all other requirements which these helmets fulfil, for example strength of retention
system or penetration for skiing helmets.
Parents need to be made aware that the protection given by a helmet depends on the circumstances of
the accident and wearing of a helmet cannot always prevent injury, death or disability.
Cycle related activities can result in a broad spectrum of accident situations. Most accident statistics
relates to cycle accidents and less is written about the accident situation for other activities such as roller
sports and sledging. Depending on the cycle accident situation the helmet and head can be loaded in
compression and also with a tangential force leading to rotation of the helmet and head. The most
common cycle accident for cyclists are single accidents to the ground. The impact surface can alter from
asphalt, gravel and other impact surfaces. To capture the overall accident situation, the test methods
defined in this document are designed to take as many aspects as possible into account without
restricting the usability of the helmet.
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 can be damaged in absorbing this energy.

tests on these samples. The smallest applicable headform size is used for the rotational shock absorbing
capacity tests using helmet sample five and six. Four conditions are applied. A hot condition
(+ 50 °C ± 2 °C), a cold condition (- 20 °C ± 2 °C) and ageing condition (5.3.1.2.3 or Annex A) and an

5.2.4 Assessment of the helmet’s marking and information
An assessment of the helmet's marking and information supplied by the manufacturer shall be
performed.
The durability of the markings as specified in 6 is verified by rubbing the marking by hand for 15 s with
a piece of cotton cloth soaked with water. The inspection shall be carried out by a person with normal
vision to determine if the marking remains legible.
5.2.5 Assessment of the buckle adjustment capability
Perform an assessment of the requirement in 4.6.3 by fitting the helmet on all headforms that fit within
the helmets size range and by positioning it according to the manufacturer’s instructions or in the manner
in which the helmet is intended to be worn on the head.
5.3 Determination of shock absorbing capacity
5.3.1 Linear shock absorption
5.3.1.1 Test area for linear shock absorption
a) Take a headform of appropriate size designation and mark a point B, 6,35 mm above the reference
plane (3.8) back of the headform (see Figure 1 and Figure 2).
b) Place the helmet on the headform. Apply a vertical load of 50 N on the crown of the helmet in order to
stabilize the helmet on the headform. Position the front edge of the helmet to meet the upwards field of
vision specified in 4.3 or to the manufacturer's normal wearing position, if this is detailed by the
manufacturer and results in greater than the specified upwards vision.
c) Draw the AA′′ line (in the AA′ plane) on the helmet.
d) Draw a line on the helmet, (line 1 in Figure 2), parallel to and approximately 20 mm above the AA′′ line
(for use as an angular measurement datum line).
e) Mark the helmet at points B1 and B2. These points are the sideways horizontal projection of point B
on to the outer surface of the helmet.
f) Draw a line RR′ on the helmet passing through B1 and B2, the line being angled 10° upwards toward
the front of the helmet relative to the datum line drawn in d).
The area above the line drawn in f) is the test area for impacts on to the flat anvil. The area above the line
RWA′′ is the test area for impacts on to the kerbstone anvil, point W being the intersection of the lines
marked in accordance with c) and f) above.
