ISO 10256-2:2016 specifies performance requirements and test methods for head protectors for use in ice hockey and is intended to be read in conjunction with ISO 10256-1. 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 vision; f) marking and information. ISO 10256-2:2016 applies to head 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 of this part of ISO 10256 is to reduce the risk of injury to the head without compromising the form or appeal of the game.
