ISO 10256-3:2016

ISO 10256-3:2016 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:
a) construction and area of coverage;
b) resistance to puck impact;
c) penetration;
d) field of vision;
e) geometric (visual) optics and acuity;
f) transmittance and haze;
g) marking and information.
ISO 10256-3:2016 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.
