1、Designation: F 1163 04aAn American National StandardStandard Specification forProtective Headgear Used in Horse Sports and HorsebackRiding1This standard is issued under the fixed designation F 1163; the number immediately following the designation indicates the year oforiginal adoption or, in the ca

2、se of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.INTRODUCTIONHorse sports and horseback riding are sports with intrinsic hazards. It is recognized tha

3、t 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 protective headgear is w

4、orn. 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 factors, andbio

5、mechanical 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 specifies a labor

6、atory 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 covers minimum

7、 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 specification.1.3 Al

8、l testing and requirements of this specification shallbe in accordance with Test Methods F 1446, except wherenoted herein.1.4 The values stated in SI units are to be regarded as thestandard.1.5 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It i

9、s theresponsibility 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.

14、, United States.F 1446. The appropriate size headform shall be selected (seedefinition of headform size selection in the Terminologysection of Test Methods F 1446) for the helmet to be tested.5. Anvils and Impact Velocities5.1 Anvils to be used for impact tests in this specificationare the flat anvi

15、l described in the section and figure on FlatAnvil of Test Methods F 1446, and the equestrian hazard anvildescribed in Fig. 1 of this specification. 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 ra

16、il 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 atheoretical 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 theoretica

17、l 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 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 hea

18、dform in accordancewith the definition of headform size selection in the Terminol-ogy section of Test Methods F 1446.6.2 Position the helmet in accordance with the section onTest Procedures of Test Methods F 1446.6.3 All helmets shall meet the requirements of the sectionson Configuration, Materials,

19、 and Internal Projection of TestMethods F 1446.6.3.1 All reporting shall be described in the section onReporting of Test Methods F 1446.6.3.2 Use the method described in the section on ReferenceMarking of Test Methods F 1446.6.4 Maintaining the force and position described in thissection, draw the t

20、est line on the outer surface of the helmet asshown in Fig. 2. Helmet impacts shall be made with the flatanvil centered on or above the test line described in Fig. 2, andwith no part of the top ridge of the equestrian hazard anvilextending below the test line described in Fig. 26.5 Measure periphera
