Standard Specification for
Protective Headgear with Faceguard Used in Bull Riding
This standard is issued under the fixed designation F2530; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (´) indicates an editorial change since the last revision or reapproval.
INTRODUCTION
Bull riding is a sport with intrinsic hazards. It is recognized that it is not possible to write a
protective headgear with faceguard standard specification that will result in headgear with faceguards
that can protect against injury or death in all accidents. Because of complex interactions of variables
such as bull motion, bull size and weight, rider size, direction and point of impact, and individual
differences in reaction to impact forces, it must be kept in mind that injuries are still possible. It is also
recognizedthatseriousinjuryordeathcanresultfrombothlow-energyandhigh-energyimpacts,even
when protective headgear with faceguard is worn. It is further recognized that protective headgear
with faceguards must be acceptable to the user and to the regulating associations or agencies requiring
its use.
In bull riding, where the force of impact between the bull and the face of the rider can cause head
and facial injury, there is a need for both head and facial protection.After careful consideration of the
mechanisms and forces involved in this context, this standard specification for headgear with
faceguards has been prepared, using resources in medical, scientific, mechanical engineering, human
factors, and biomechanical fields.
This specification is a series of laboratory tests of the protective headgear with faceguard. The
headgear testing measures its ability to reduce head acceleration when impacting various shaped
objects. The faceguard testing checks its ability to limit contact with the user face to reduce the
potential for facial injuries.
This specification incorporates many aspects of other 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 remain
in its normal position on the wearer’s head during bull riding and impact conditions;
(2) The physical characteristics of materials used in construction of the headgear with faceguard
should retain their shock-absorbing characteristics under the influence of aging, use, or exposure to
typical environmental conditions;
(3) The faceguard should not significantly interfere with the vision of the wearer; and
(4) In the event of injury, the headgear with faceguard should be removable without causing
movement to the cervical spine. The access provided shall be sufficient for the administration of
cardiopulmonary resuscitation to the wearer.
