3、headgear with faceguard standard specification that will result in headgear with faceguardsthat can protect against injury or death in all accidents.Because of complex interactions of variablessuch as bull motion,bull size and weight,rider size,direction and point of impact,and individualdifferences
4、 in reaction to impact forces,it must be kept in mind that injuries are still possible.It is alsorecognized that serious injury or death can result from both low-energy and high-energy impacts,evenwhen protective headgear with faceguard is worn.It is further recognized that protective headgearwith f
5、aceguards must be acceptable to the user and to the regulating associations or agencies requiringits use.In bull riding,where the force of impact between the bull and the face of the rider can cause headand facial injury,there is a need for both head and facial protection.After careful consideration
6、 of themechanisms and forces involved in this context,this standard specification for headgear withfaceguards has been prepared,using resources in medical,scientific,mechanical engineering,humanfactors,and biomechanical fields.This specification is a series of laboratory tests of the protective head
7、gear with faceguard.Theheadgear testing measures its ability to reduce head acceleration when impacting various shapedobjects.The faceguard testing checks its ability to limit contact with the user face to reduce thepotential for facial injuries.This specification incorporates many aspects of other
8、recognized headgear standard specifications.Other intentions that were not amenable to testing or inspection are offered as guidelines:(1)The chin strap should be attached in a manner to enable the headgear with faceguard to remainin its normal position on the wearers head during bull riding and imp
9、act conditions;(2)The physical characteristics of materials used in construction of the headgear with faceguardshould retain their shock-absorbing characteristics under the influence of aging,use,or exposure totypical environmental conditions;(3)The faceguard should not significantly interfere with
10、the vision of the wearer;and(4)In the event of injury,the headgear with faceguard should be removable without causingmovement to the cervical spine.The access provided shall be sufficient for the administration ofcardiopulmonary resuscitation to the wearer.1.Scope1.1 This specification covers perfor
11、mance requirements anddescribes test methods for protective headgear with faceguardsfor use in bull riding.1.2 All testing and requirements of this specification shallbe in accordance with Test Methods F1446,except where notedherein.1.3 Partial utilization of this specification is prohibited.Anystat
12、ement of compliance with this specification shall be acertification that the headgear with faceguard meets all of therequirements of the specification in their entirety.A headgearwith faceguard that fails to meet any one of the requirements ofthis specification is considered to have failed the speci
