4、ification.In addition,the issue of multiple sub-concussive impacts is notaddressed here.NoteProtection provided by headgear satisfying this specification is not equivalent tothe protection provided by rigid“helmets”used in many other sports activities.Headgear that meetsthese standard specifications
5、 may not provide significant protection in some head impact situations.This specification is intended to be used with other standards and documents listed in theReferenced Documents.1.Scope1.1 This specification defines performance requirements forheadgear used for participation in the sport of socc
6、er.Thetechnical requirements in this specification do not address theadministrative requirements of soccer governing bodies,so itshould not be assumed that any headgear satisfying thisspecification will be acceptable for use in sanctioned soccerevents.1.2 This specification is intended to reduce the
7、 forces fromexternal physical sources reaching the defined impact area ofthe head in impacts that may occur in the sport of soccer.Noheadgear can provide protection against all impacts,foresee-able or not.This specification does not address the potential forinjury from any type of impact.The tests s
8、pecified in thisspecification are laboratory simulation tests only,and do notpurport to create situations identical to the impacts that mayoccur during the playing of soccer.1.3 All testing and requirements of this specification shallbe in accordance with Test Methods F1446,except where notedherein.
9、In the event of a discrepancy between the requirementsof this specification and those of Test Methods F1446,thisspecification shall prevail.1.4 Partial utilization of this specification is prohibited.Anystatement of compliance with this specification shall be acertification that the headgear meets a
10、ll of the requirements ofthis specification in its entirety.Headgear that fails to meet anyone of the requirements of this specification is considered tohave failed the specification and should not be sold with anyindication that it meets parts of the specification.1.5 The values stated in SI units
11、are to be regarded as thestandard.1.6 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 practices and determine the applica-bility of regulatory limitatio
