1、Designation: F2748 14F2748 15Standard Specification forLow Energy Air Airsoft Guns1This standard is issued under the fixed designation F2748; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision. A number in pa
2、rentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.INTRODUCTIONTo perform as intended, a low energy air an airsoft gun requires a level of power which, if misused,can cause serious injury. This specification is
3、 intended to reduce the hazards associated with lowenergy air airsoft gun use. This specification cannot control careless use or eliminate all hazards ofmisuse. Terminology is standardized in this specification, so that conforming products will beidentified in the same manner, and critical dimension
4、s are standardized to assure safe interchange-ability of projectiles in all conforming low energy air airsoft guns. Product performance hazards areidentified and requirements are established to minimize these hazards. This specification is writtenwithin the current state-of-the-art of low energy air
5、 airsoft gun technology. The intent is to revise thisspecification whenever substantive information becomes available which justifies revising existingrequirements or adding new requirements.1. Scope1.1 This specification covers low energy air airsoft guns which propel a projectile by means of energ
