Standard Specification for Face Guards for Youth Baseball
ABSTRACT
This specification covers protective face guards designed to be attached to a pre-existing helmet for youth baseball. General requirements for protective face guards shall include mechanical strength, durability, flexibility, finish, padding, attachment system, and shall not cause skin irritation. The face guard shall undergo velocity and impact testing using apparatus such as headform and mounting, ball propelling device, and gage.
SCOPE
1.1 This specification covers protective face guards for sports such as youth baseball (batters and baserunners).
1.2 This type of face guard is designed to be attached to a pre-existing helmet.
1.3 The equipment covered by this specification is intended to reduce hazards of injury to the face, including eyes and mouth, due to impacts from baseballs or softballs.
1.4 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
1.5 The following precautionary caveat pertains only to the test method portion, Section 5, of this specification: 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
In baseball, or similar sports, where the force of a pitched, hit, or deflected ball can cause facial
injury, there is a need for head, facial, eye, and teeth protection. After careful consideration of the
mechanisms and forces involved in this context, this specification for eye and facial protective
equipment has been prepared.
The impact test is designed to approximate the impact of a direct perpendicular blow from a
baseball traveling at 30 m/s (67.1 mph). These speeds have been confirmed by actual measurements
on baseballs thrown by youth league pitchers. Performance and design requirements developed on this
basis are intended to minimize injury and to prolong the useful life of the equipment. However,
because of complex interactions of variables such as ball speed, direction and point of impact, and
particularly, individual differences in reaction to impact forces, it must be kept in mind that some
injuries, even some serious injuries, are still possible.
