Protective equipment for use in ice hockey - Part 3: Face protectors for skaters (ISO 10256-3:2016)

This International Standard specifies performance requirements and test methods for face protectors (including visors) for use in ice hockey and shall be used in conjuction with ISO 10256-1.
Note 1   The requirements of a clause take precident over a figure.   
Note 2   The intent is to reduce the risk of injury to the face 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 face protectors used for ice hockey.  Ice hockey face protectors 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 face protector in accordance with this International Standard.
Requirements and the corresponding test methods, where appropriate, are given for the following:
a)   Construction and area of coverage
b)   resistance to puck impact
c)   penetration
d)   field of view and scotoma
e)   geometric (visual) optics and acuity
f)   transmittance and haze
g)   marking and information.
This International Standard applies to  face protectors worn  by:
a)   players other than goalkeepers; and
b)   certain functionaries (e.g. referees).

NOTE 1       Les exigences d'un article prévalent sur celles d'une figure.
NOTE 2       L'objectif est de réduire le risque de blessure au visage sans compromettre pour autant l'aspect ou l'attrait même du jeu.

Varovalna oprema za uporabo pri hokeju na ledu - 3. del: Ščitniki za obraz za drsalce (ISO 10256-3:2016)

Ta mednarodni standard določa zahteve glede učinkovitosti in preskusne metode za ščitnike za obraz (vključno z vizirji) za uporabo pri hokeju na ledu, uporabljati pa ga je treba skupaj s standardom ISO 10256-1. Opomba 1: Zahteve točke imajo prednost pred številsko vrednostjo.    Opomba 2: Namen je zmanjšati tveganje za poškodbe obraza brez vpliva na način ali privlačnost igre. Opomba 3: Hokej na ledu je šport, ki vključuje tveganja za poškodbe.  Ta mednarodni standard je namenjen le ščitnikom za obraz, ki se uporabljajo pri hokeju na ledu.  Ščitniki za obraz za hokej na ledu ne zagotavljajo nobene zaščite pred poškodbami vratu ali hrbtenice. V skladu s tem mednarodnim standardom lahko pride do hudih poškodb glave, možganov ali hrbtenice oziroma paralize ali smrti navkljub uporabi ščitnika za obraz za hokej na ledu. Zahteve in ustrezne preskusne metode veljajo (kjer je to primerno) za:
a) izdelavo in območje pokritosti; b) odpornost proti udarcu ploščka;
c) prepustnost; d) vidno polje in skotom; e) geometrično (vidno) optiko in ostrino;
f) prepustnost svetlobe in zamegljenost; g) označevanje in podatke. Ta mednarodni standard se uporablja za ščitnike za obraz, ki jih uporabljajo:  a) igralci, ki niso vratarji; in
b) nekateri funkcionarji (npr. sodniki).

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.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).

Introduction
Ice hockey is a high speed, collision sport in which there is a risk of injury. The object of this part of
ISO 10256 is to specify requirements for face protectors, taking into account the risks inherent in
participating in the sport, many of which cannot be eliminated by protective equipment. By playing this
sport, participants accept the risk of serious injury, paralysis, or death.
The intention of 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.
Face protectors can consist of eye protectors (visors) or full face protectors. They are always worn
in conjunction with an ice hockey helmet. Face protectors are 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 is intended to be as closely fitting as possible consistent with comfort. In use
it is essential that the helmet and associated face protector are securely fastened, with any chin strap
or neck strap adjusted according to manufacturer’s instructions.

Face protectors for skaters
1 Scope
This part of ISO 10256 specifies performance requirements and test methods for face protectors
(including visors) for use in ice hockey and is intended to be used in conjunction with ISO 10256-1.
Requirements and the corresponding test methods, where appropriate, are given for the following:

b) resistance to puck impact;
c) penetration;
d) field of vision;
e) geometric (visual) optics and acuity;

g) marking and information.
This part of ISO 10256 applies to face protectors worn by
— players other than goalkeepers, and
— certain functionaries (e.g. referees).
NOTE 1 The requirements of a Clause take precedent over a figure.
NOTE 2 The intent is to reduce the risk of injury to the face without compromising the form or appeal of
the game.
