Standard Specification for Protective Headgear Used in Horse Sports and Horseback Riding
ABSTRACT
This specification provides a description of a test method for protective headgear used in horse sports and horseback riding that will measure the ability of the headgear to reduce head acceleration when impacting objects of various shapes. Materials covered by this specification include the pair of appropriate size headform and helmet and the anvils for the impacts tests, which consist of the flat anvil and the equestrian hazard anvil. The helmet shall be conditioned in the following environments: ambient, low temperature, high temperature, and water immersion, and shall be impacted at each of four sites centered on or anywhere above the center of the impact line (two sites on the flat anvil and two sites on the equestrian hazard anvil). Dynamic loading and helmet stability tests shall be performed and shall conform to the requirements specified.
SCOPE
1.1 This specification covers minimum performance criteria and describes test methods for protective headgear for use in horse sports and horseback riding.
1.2 It is not the intention of this specification to bar from consideration materials of improved quality or performance not known at the time of development of this specification.
1.3 All testing and requirements of this specification shall be in accordance with Test Methods F1446, except where noted herein.
1.4 The values stated in SI units are to be regarded as the standard.
1.5 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

INTRODUCTION
Horse sports and horseback riding are sports with intrinsic hazards. It is recognized that it is not
possible to write a protective headgear performance standard that will result in headgear that can
protect against injury or death in all accidents. It is also recognized that serious injury or death can
result from both low-energy and high-energy impacts, even when protective headgear is worn. It is
further recognized that protective headgear must be acceptable to the user and to the regulating
associations or agencies requiring its use. Acknowledging these limitations, this specification was
developed using resources in medical, scientific, mechanical engineering, human factors, and
biomechanical 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. These
standards may be referenced. It should be noted that this specification specifies a laboratory test of
completed headgear to measure its ability to reduce head acceleration when impacting various shaped
objects. It is known that headgear that performs well under this specification will mitigate head injury
in actual use within its design limits.
