1、Designation: F1163 15 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 adoption or, in the case

2、 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 recognized that i

3、t 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 worn

4、. 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, andbiomec

5、hanical 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 laborato

6、ry 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 pe

7、rformance 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 All t

8、esting 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 are included in thi

9、sstandard.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 prior to use.2. Re

Headforms4.1 Headforms to be used in this specification are inaccordance with the section on Apparatus of Test MethodsF1446. The appropriate size headform shall be selected (seedefinition of headform size selectio

15、n in the Terminologysection of Test Methods F1446) for the helmet to be tested.4.2 Test headforms used in this specification shall use thevariable mass drop assembly configuration for impact testingas specified in the definition of test headforms in the terminol-ogy section and in Table 2 of Test Me

16、thods F1446.5. 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 specification. The circular portion ofthe eques

17、trian 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 atheoretical drop height of 1.8 m to achi

18、eve 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 for each test and shall be within 63

19、% 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 accordance with the section onTest Pro
