1、Designation: F1163 04a (Reapproved 2011)An American National StandardStandard Specification forProtective Headgear Used in Horse Sports and HorsebackRiding1This standard is issued under the fixed designation F1163; the number immediately following the designation indicates the year oforiginal adopti
2、on or, in the case of revision, 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.INTRODUCTIONHorse sports and horseback riding are sports with intrinsic hazards. It is
3、 recognized that it is notpossible to write a protective headgear performance standard that will result in headgear that canprotect against injury or death in all accidents. It is also recognized that serious injury or death canresult from both low-energy and high-energy impacts, even when protectiv
4、e headgear is worn. It isfurther recognized that protective headgear must be acceptable to the user and to the regulatingassociations or agencies requiring its use. Acknowledging these limitations, this specification wasdeveloped using resources in medical, scientific, mechanical engineering, human
5、factors, andbiomechanical fields.This specification incorporates many aspects of other recognized headgear performance standards.This specification draws from work done by others where appropriate for this specification. Thesestandards may be referenced. It should be noted that this specification sp
6、ecifies a laboratory test ofcompleted headgear to measure its ability to reduce head acceleration when impacting various shapedobjects. It is known that headgear that performs well under this specification will mitigate head injuryin actual use within its design limits.1. Scope1.1 This specification
7、 covers minimum performance criteriaand describes test methods for protective headgear for use inhorse sports and horseback riding.1.2 It is not the intention of this specification to bar fromconsideration materials of improved quality or performance notknown at the time of development of this speci
8、fication.1.3 All testing and requirements of this specification shallbe in accordance with Test Methods F1446, except where notedherein.1.4 The values stated in SI units are to be regarded as thestandard.1.5 The values stated in SI units are to be regarded asstandard. No other units of measurement a
9、re included in thisstandard.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 limitations

Anvils and Impact Velocities5.1 Anvils to be used for impact tests in this specificationare the flat anvil described in the section and figure on FlatAnvil of Test Methods F1446, and the equestrian hazard anvildescribed in Fig. 1 of this specificat
16、ion. The circular portion ofthe equestrian hazard anvil shall have a radius of 66.7 6 0.5mm, with facial surfaces inclined at an angle of 45 6 2. Theedge rail at the intersection of the facial surfaces shall have aradius of 0.4 mm maximum.5.2 The helmet shall be dropped onto the flat anvil from athe
17、oretical drop height of 1.8 m to achieve an impact velocityof 6.0 m/s 6 3%.5.3 The helmet shall be dropped onto the equestrian hazardanvil from a theoretical drop height of 1.3 m to achieve animpact velocity of 5.0 m/s 6 3%.5.4 The impact velocity shall be measured during the last 40mm of free-fall
18、for each test and shall be within 63 % of thevelocities specified in 5.2 and 5.3.6. General Requirements and Marking6.1 Select the appropriate reference headform in accordancewith the definition of headform size selection in the Terminol-ogy section of Test Methods F1446.6.2 Position the helmet in a
