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 10256 was prepared by Technical Committee ISO/TC 83, Sports and recreational equipment,
Subcommittee SC 5, Ice hockey equipment and facilities.

ISO 10256:2003(E)
Introduction
The intention of head and face protection is to reduce the frequency and severity of localized injuries to the
head and that part of the face surrounded by the protector. The protective function is such that the force from
impacts against the protector is distributed and dampened and the penetration of objects is counteracted.
Head and face protection for use in ice hockey comprise helmets and an associated face protector. Face
protectors can consist of eye protectors (visors) or full-face protectors. Helmets are tested and assessed as a
separate unit, but face protectors are always tested and assessed together with the helmet or helmets for
which the face protector is intended.
To achieve the performance of which it is capable, and to ensure stability on the head, a helmet and
associated face protector should be as closely fitting as possible consistent with comfort. In use, it is essential
that the helmet and associated face protector be securely fastened, with any chin strap or neck strap adjusted
according to the manufacturer's instructions.
ISO/TC 83/SC 5 is aware that specifications for the performance of the helmet and the face protector are
required to reduce the risk of injury in ice hockey. There was consensus that most of today's head and face
protectors meet the performance requirements of this International Standard. However, the goal of
ISO/TC 83/SC 5 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. ISO/TC 83/SC 5 is also aware that in order to provide
for comfort and correct fitting and use, helmets and face protectors should have low mass consistent with
providing the appropriate performance characteristics.

INTERNATIONAL STANDARD ISO 10256:2003(E)

Head and face protection for use in ice hockey
1 Scope
This International Standard specifies performance requirements and test methods for head and face
protection for use in ice hockey.
NOTE 1 The intent is to reduce the risk of injury to the head and face without compromising the form or appeal of the
game.
NOTE 2 Ice hockey is a sport in which there is a risk of injury. This International Standard is intended only for helmets
and face protectors 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.
Performance requirements and test methods, where appropriate, are given for the following:
a) construction;
b) shock absorption;
c) puck-impact resistance;
d) penetration;
e) retention-system properties;
f) field of vision;
g) marking and information.
The head and face protection is intended for use by
a) players,
b) goalkeepers and
c) certain functionaries (e.g. referees).
