1、Designation: F1587 12a An American National StandardStandard Specification forHead and Face Protective Equipment for Ice HockeyGoaltenders1This standard is issued under the fixed designation F1587; the number immediately following the designation indicates the year oforiginal adoption or, in the cas
2、e of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.INTRODUCTIONIce hockey is a contact sport with intrinsic hazards. The use of protective equipment will
3、noteliminate all injuries but should substantially reduce the severity and frequency of many injuries.Participation in the sport of ice hockey by a player implies acceptance of some risk of injury. The goalis to reduce the risk.This performance specification for ice hockey goaltender head and face p
4、rotective equipment hasbeen prepared after consideration of head and face protection relative to the following principle risks:high-mass/low-velocity impact with respect to head protection, low-mass/high-velocity with respect toface protection (various playing situations), and fit. This performance
5、specification may be modifiedas other risks are identified.Performance requirements were determined after consideration of the state of the art of head andface protective design and manufacture. This specification was developed to address the uniquedemands and hazards associated with the position of
6、 ice hockey goaltender.Two types of protectors are designated. Both types are subject to impact resistance and shockattenuation requirements. Type I protectors are subject to hockey stick blade penetration resistancerequirements over their entire area of coverage. Type II protectors are subject to h
7、ockey puckpenetration resistance requirements within the area of the field of vision and hockey stick bladepenetration resistance requirements over the remainder of the area of coverage. It is recommended thatType II protectors be used only by players 18 years of age and older.1. Scope1.1 This perfo
8、rmance specification2covers performancerequirements for ice hockey goaltender head and face protec-tors.1.2 The intent of this performance specification is to reducethe risk of injury to the head and face of ice hockey goaltenderswithout compromising the form and appeal of the game.1.3 This specific
9、ation has requirements for: (1) materials,assembly, and design; (2) protected areas (coverage) andpenetration resistance; (3) shock absorption; (4) puck impactresistance; (5) extensibility and strength of the chin strap andits attachment; and (6) optical quality.1.4 UnitsThe values stated in SI unit
10、s are to be regardedas the standard. No other units of measurement are included inthis standard.1.5 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety and health p
