1、Designation: F1045 16 An American National StandardStandard Performance Specification forIce Hockey Helmets1This standard is issued under the fixed designation F1045; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last

2、 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 noteliminate all injuries but s

3、hould substantially reduce the severity and frequency of injury. Participationin the sport of ice hockey by a player implies acceptance of some risk of injury. The goal is tominimize this risk.This performance specification for head protective equipment has been prepared after considerationof head p

4、rotection relative to the following principle risks: high-mass, low-velocity impact (variousplaying situations), and fit. This performance specification may be modified as other risks areidentified.Performance requirements were determined after consideration of state-of-the-art of helmet designand m

5、anufacture and the demands of the sport.1. Scope1.1 This performance specification2covers performancerequirements for ice hockey helmets.1.2 The intent of this performance specification is to reducethe risk of injury to the head without compromising the formand appeal of the game.1.3 This performanc

6、e specification covers: (1) performancetests for shock absorption properties of the complete helmetand strength and elongation of the chin strap and its attach-ment; and (2) requirements for area of coverage and penetra-tion.1.4 The values stated in SI units are to be regarded asstandard. The values

7、 given in parentheses are for informationonly.1.5 The following precautionary caveat pertains only to thetest methods portion, Section 12, of this performance specifi-cation: This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility

8、 of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.
