1、Designation: F2439 06 (Reapproved 2016)F2439 17 An American National StandardStandard Specification forHeadgear Used in Soccer1This standard is issued under the fixed designation F2439; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revisio
2、n, 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.INTRODUCTIONSoccer is a sport with inherent risks. Participation in the sport implies acceptance of risk of injury.
3、This specification was developed to address forces of some of the incidental (non-ball) head impactsthat may occur while engaging in soccer. Although headgear satisfying this specification may providelimited protection against heading impacts which are generally sub-concussive, heading impacts areno
4、t addressed by this specification. 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 meet
5、sthese standard specifications 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 for headgear used for pa
6、rticipation in the sport of soccer. The technicalrequirements in this specification do not address the administrative requirements of soccer governing bodies, so it should not beassumed that any headgear satisfying this specification will be acceptable for use in sanctioned soccer events.1.2 This sp
7、ecification is intended to reduce the forces from external physical sources reaching the defined impact area of thehead in impacts that may occur in the sport of soccer. No headgear can provide protection against all impacts, foreseeable or not.This specification does not address the potential for i
8、njury from any type of impact. The tests specified in this specification arelaboratory simulation tests only, and do not purport to create situations identical to the impacts that may occur during the playingof soccer.1.3 All testing and requirements of this specification shall be in accordance with
9、 Test Methods F1446, except where notedherein. In the event of a discrepancy between the requirements of this specification and those of Test Methods F1446, thisspecification shall prevail.1.4 Partial utilization of this specification is prohibited. Any statement of compliance with this specificatio
10、n shall be acertification that the headgear meets all of the requirements of this specification in its entirety. Headgear that fails to meet any oneof the requirements of this specification is considered to have failed the specification and should not be sold with any indicationthat it meets parts o
11、f the specification.1.5 The values stated in SI units are to be regarded as the standard.1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibilityof the user of this standard to establish appropriate safety safety, health, and
12、 healthenvironmental practices and determine theapplicability of regulatory limitations prior to use.1.7 This international standard was developed in accordance with internationally recognized principles on standardizationestablished in the Decision on Principles for the Development of International

The headform anvil shall be positioned such that the only impact between the drop headform and the impactanvil is at the selected impact location, with no other parts of the headform and anvil coming into contact with each other duringthe initial impact. The headform an
