Foreword
ISO (the International Organization for Standardization) is a worldwide federation of
national standards bodies (ISO member bodies). The work of preparing International
Standards is normally carried out through ISO technical committees. Each member body
interested in a subject for which a technical committee has been established has the right to
be represented on that committee. International organizations, governmental and non-
governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with
the International Electrotechnical Commission (IEC) on all matters of electrotechnical
standardization.
International Standards are drafted in accordance with the rules given in the
ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft
International Standards adopted by the technical committees are circulated to the member
bodies for voting. Publication as an International Standard requires approval by at least
75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the
subject of patent rights. ISO shall not be held responsible for identifying any or all such
patent rights.
ISO was prepared by Technical Committee ISO/TC 83, Sports Equipment, Subcommittee
SC 5, Equipment and facilities for ice hockey.
ISO 10256-1, 10256-2, 10256-3 and 10256-4 replace the second edition of ISO 10256
(2003)
ISO 10256 consists of the following parts, under the general title Protective Equipment for
use in Ice hockey:
 Part 1: General requirements
 Part 2: Head protection for skaters – performance requirements
 Part 3: Facial protection for skaters– performance requirements
 Part 4: Head and face protection for goalkeepers – performance requirements

Introduction
The intention of head protection is to reduce the frequency and severity of localized injuries
to the head. The protective function is such that the force from impacts against the protector
is distributed and dampened and the penetration of objects is counteracted.
Part of the head protection for use in ice hockey consists of a helmet. To achieve the
performance of which it is capable, and to ensure stability on the head, a helmet should be
as closely fitting as possible consistent with comfort. In use it is essential that the helmet is
securely fastened, with any chin strap or neck strap adjusted according to manufacturer’s
instructions.

Sub-committee 5 is aware that specifications for the performance of the helmet are required
to reduce the risk of injury in ice hockey. There was consensus that most of today’s head
protectors meet the performance requirements of this standard. The goal of the sub-
committee is to promote the use of better materials and/or constructions as they become
available to meet the future requirements of the sport of ice hockey. Sub-committee 5
recognizes that in order to provide for comfort, fit and use, helmets should have a mass
consistent with providing the appropriate performance characteristics.

ISO/DRAFT

Protective equipment for use in ice hockey – Part 2: Head
protection for skaters
1 Scope
This International Standard specifies performance requirements and test methods for head
protectors for use in ice hockey and shall be used in conjunction with ISO 10256-1.
NOTE 1 The requirements of a clause take precident over a figure.
NOTE 2 The intent of this International Standard is to reduce the risk of injury to the head without
compromising the form or appeal of the game.
NOTE 3 Ice hockey is a sport in which there is a risk of injury. This International Standard is intended only
for helmets used for ice hockey. Ice hockey helmets afford no protection from neck or spinal injury. Severe
head, brain or spinal injuries, including paralysis or death, may occur in spite of using an ice hockey helmet in
accordance with this International Standard.
Requirements and the corresponding test methods, where appropriate, are given for the
following:
a) Construction and protected area
b) shock absorption
c) penetration
d) retention system properties
e) field of view
f) marking and information.

This International Standard applies to head protectors worn by
a) Players other than goalkeepers; and
b) certain functionaries (e.g. referees).

5 Test methods
5.1 Sampling
Only new and complete helmets as offered for sale shall be tested. The minimum number of
samples needed for a complete test is found in TABLE1.
5.2 Conditioning Temperatures
Helmet samples shall be conditioned under ambient, low and elevated temperatures in
accordance with ISO 10256-1.
5.3 Determination of field of view
The upward field of view is the solid angle bounded by the reference plane of the headform
and a second plane tilted 35° upwards from the reference plane. This second plane
intersects the reference plane at two points on the front surface of the headform that are 31
mm to the right and left of the median plane.
The left horizontal field of view is the angle bounded a plane parallel and 31 mm to the left
of the median plane of the headform and a second plane perpendicular to the median plane
(i.e. rotated 90° horizontally) and parallel to the lateral plane. The two planes intersect with
the reference plane at the front surface of the headform at a point located 31mm to the left
of the median plane.
The right horizontal field of view is the angle bounded a plane parallel and 31 mm to the
right of the median plane of the headform and a second plane perpendicular to the median
plane (i.e. rotated 90° horizontally) and parallel to the lateral plane. The two planes intersect
with the reference plane at the front surface of the headform at a point located 31mm to the
right of the median plane.
The accuracy of the device used to measure field of view shall be +/- 1 degree. An example
of a field of view measurement device is shown in Annex C.

5.4 Determination of head positioning index (HPI)
The HPI and corresponding headform size shall be provided by the helmet manufacturer.
Where the HPI and corresponding headform size are not available from the manufacturer,
the helmet shall not be tested.
5.5 Determination of protected area
Position the helmet on the largest full headform for the helmet’s size range using the helmet
positioning index (HPI). Apply a load of 50 N to the crown of the helmet in order to seat the
helmet to the headform. The helmet shall cover the area of protection as required in Clause
4.4 and Figure 3.

5.6 Determination of penetration characteristics
5.6.1 Test apparatus
The apparatus shall consist of:
a) a headform in accordance with EN 960; and
6 Error! Reference source not found.

---------------------- Page: 14 ----------------------
oSIST prEN ISO 10256-2:2015

b) a steel test blade in accordance with Figure 5.

5.6.2 Procedure
5.6.2.1 Helmet Positioning
The helmet shall be positioned on the largest headform for its size range, using the HPI.
5.6.2.2 Penetration Test
Attempt to pass the end of the test-blade, without force, through all openings of the helmet
(except the ear apertures) within the protected area (see Figure 3).
Any contact, or lack thereof, with the bare headform surface shall be recorded.
5.7 Determination of shock absorbing capacity
5.7.1 Impact sites
Impact sites shall be six prescribed sites (See definition) (see Figure 1) and two non-
prescribed sites. The impact direction shall be perpendicular to the headform surface at all
impact sites.
Each of the two non-prescribed impacts shall be located on the headform on or above the
test line. Each of these two non-prescribed impact sites shall be at least one-fifth of the
circumference of the headform from any prior impact location on that helmet. The headform
shall be positioned so that the impact location is the first point of contact with the anvil. The
helmet shall then be positioned on the headform as specified by the manufacturer’s HPI.
The resulting two non-prescribed impacts shall be identified by
(a) the arc distance along the reference plane from the anterior intersection of the median
and reference planes (either clockwise or counter-clockwise); and
(b) the perpendicular arc distance above or below that point on the reference plane.

5.7.2 Marking impact locations on headform
