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

6、 ocular and facial injurieswill 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

7、 of 70 mm (2.8 in.) (per accepted 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 subje
