1、Designation:F177610 Designation: F1776 12An American National StandardStandard Specification forEye Protective Devices for Paintball Sports1This standard is issued under the fixed designation F1776; 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 () indicates an editorial change since the last revision or reapproval.INTRODUCTIONThis is the specification for eye, face, and head protective devices, or EHPD, to be used
3、in the sportof paintball. Paintball is a sport that, like all sports, has intrinsic hazards. These hazards include beinghit by paintballs. Protective equipment cannot eliminate all injuries but will substantially reduce theirseverity and frequency. Participation in this sport by a player implies acc
4、eptance of injury risk. Thegoal of protective equipment is to minimize the risk of injury.Performance requirements are presented and are intended to minimize injury with minimalimpairment of the form and appeal of the sport. This specification is subject to revision as indicatedby subsequent injury
5、statistics.The impact requirements are designed to give eye, adnexa of eye, and head protection from paintballimpacts likely to be encountered under game conditions. While the EHPD also may protect the userfrom other potential impacts, such as running into tree branches, there are many conceivable i
6、mpacts,including falls from heights, which could exceed the specification and result in eye injury despite theuse of the EHPD.1. Scope1.1 This specification applies to eye, face, and head protective devices, designed for use by players of the sport of paintball,which minimize or significantly reduce
7、 injury to the eye, adnexa of eye, face, and head due to paintball impact or penetration, orboth.1.2 EHPDs by nature provide three types of protection. The first type of protection is for the eyes and adnexa of eye and notnecessarily for any other parts of the face or head. The second type of protec
8、tion adds coverage for the ears and face. The thirdtype of coverage adds cranial coverage in addition to that provided to types II and III. These coverage types are defined in Section8.1.3 This specification does not limit the wearing of eyeglasses or contact lenses when used in conjunction with the
9、 EHPD.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 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibilityof the user of this standard to esta
