1、Designation: F 513 00 (Reapproved 2007)An American National StandardStandard Safety Specification forEye and Face Protective Equipment for Hockey Players1This standard is issued under the fixed designation F 513; the number immediately following the designation indicates the year oforiginal adoption

2、 or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.INTRODUCTIONIce hockey is a contact sport with intrinsic hazards. Protective equipment

3、can not eliminate allinjuries, but will substantially reduce their severity and frequency. Participation in this sport by aplayer implies acceptance of some injury risk.The goal of protective equipment is to minimize the riskof injury.After careful consideration of the mechanisms and forces involved

4、 in hockey injuries, thisspecification for eye and facial protective equipment has been prepared. A significant reduction ofoculo-facial injuries by the use of facial protective equipment is an expected result.Performance requirements are presented that are intended to minimize injury with minimalim

5、pairment of the form and appeal of the sport. The committee considers this specification aspreliminary, subject to revision as indicated by subsequent injury statistics. With these goals in mind,the impact and penetration requirements were determined. It is realized that ocular and facial injurieswi

6、ll still be possible; however, it was felt that more stringent requirements may interfere with playerperformance.In addition to the use of facial protective equipment conforming to this specification, the followingrecommendations are made: (1) A minimal stick blade width of 70 mm (2.8 in.) (per acce

7、pted rulebook limits); (2) Modification to rear blade of the ice skate to prevent penetration through wire meshmasks; (3) Stricter rules against high sticking; and (4) Stricter rules and enforcement against fighting.All of the requirements of this specification are subject to modification if future

8、statistics demonstratesignificant injuries under game conditions; (5) If full face wire protectors are used for goaltenders, athroat protector must be affixed.1. Scope1.1 This consumer safety specification covers eye and faceprotective equipment for hockey players.1.2 This specification is intended

9、to reduce the demon-strated hazards associated with the sport of ice hockey involv-ing the face including eyes.1.3 The values stated in SI units are to be regarded as thestandard. The values given in parentheses are for informationonly.1.4 The following precautionary caveat pertains only to thetest
