(Specification)Standard Specification for Low Energy Air Guns
Standard Specification for Low Energy Air Guns
SCOPE
1.1 This specification covers low energy air guns which propel a projectile by means of energy released by compressed gas, compressed CO2, mechanical springs, battery or a combination thereof, used in the sport commonly called airsoft or air soft, and is to be used in conjunction with Specification F2654.
1.2 Limitations—This specification does not cover the following types of products: Non-powder guns as specifically defined in Consumer Safety Specification F589 and which are commonly referred to as BB or pellet guns; paintball markers as specifically defined in Specification F2272; toy products; and non-recreational air guns, for example, those used by law enforcement, scientific, military, industrial, or theatrical entities.
1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.4 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.

This standard is issued under the fixed designation F2748; 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
To perform as intended, a low energy air gun requires a level of power which, if misused, can cause
serious injury. This specification is intended to reduce the hazards associated with low energy air gun
use. This specification cannot control careless use or eliminate all hazards of misuse. Terminology is
standardized in this specification, so that conforming products will be identified in the same manner,
and critical dimensions are standardized to assure safe interchangeability of projectiles in all
conforming low energy air guns. Product performance hazards are identified and requirements are
established to minimize these hazards. This specification is written within the current state-of-the-art
of low energy air gun technology. The intent is to revise this specification whenever substantive
information becomes available which justifies revising existing requirements or adding new
requirements.
