1、Designation: F1776 16 An 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 case of revision, the
2、 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 in the sportof pain
3、tball. 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 acceptance of injury r
4、isk. 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 statistics.The impa
5、ct requirements are designed to give eye, adnexa of eye, and head protection frompaintball impacts likely to be encountered under game conditions. While the EHPD also may protectthe user from other potential impacts, such as running into tree branches, there are many conceivableimpacts, including fa
6、lls from heights, which could exceed the specification and result in eye injurydespite the use of the EHPD.1. Scope1.1 This specification applies to eye, face, and head protec-tive devices, designed for use by players of the sport ofpaintball, which minimize or significantly reduce injury to theeye,
7、 adnexa of eye, face, and head due to paintball impact orpenetration, or both.1.2 EHPDs by nature provide three types of protection. Thefirst type of protection is for the eyes and adnexa of eye and notnecessarily for any other parts of the face or head. The secondtype of protection adds coverage fo
8、r the ears and face. Thethird type of coverage adds cranial coverage in addition to thatprovided to types II and III. These coverage types are definedin Section 8.1.3 This specification does not limit the wearing of eye-glasses or contact lenses when used in conjunction with theEHPD.1.4 The values s
9、tated in SI units are to be regarded as thestandard. The values given in parentheses are for informationonly.1.5 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
10、 and health practices and determine the applica-bility of regulatory limitations prior to use.2.
