Standard Specification for Low Velocity Projectile Marker
|Publication Date:||1 May 2014|
|ICS Code (Other sports equipment and facilities):||97.220.99|
1.1 This specification covers low velocity projectile markers (herein referred to as LVP marker) that propel a low velocity resilient material projectile (herein referred to as LVRM projectile as defined in Specification F2573) by means of energy released by compressed air, compressed gas, or a combination thereof, with velocity not to exceed 53.34 m/s (175 ft/s).
1.2 LVRM projectiles are made of a resilient material and have a diameter no smaller than 20 mm (0.7874 in) and no greater than 30 mm (1.18 in.). The hardness of the LVRM projectile is to be no greater than 75 Shore 00. The weight of the LVRM projectile is not to exceed 4.0 g.
1.3 The values stated in SI units are to be regarded as standard. The values given in parentheses are for information only.
1.4 The following precautionary caveat pertains only to the test method portion, Section 8, 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.

This specification covers low velocity projectile (LVP) markers that eject a low velocity resilient material (LVRM) projectile using compressed air, compressed gas, or a combination of both. Included in this specification are performance requirements and test methods for LVP markers as well as the minimum warnings and instructions that need to be provided in literature, on labels, on packaging, and on the marker itself. The LVP markers shall be manufactured to operate only in semi-automatic or pump mode and with exposed edges that shall be smooth and free of sharp edges and burrs. LVP markers shall be provided with a disabling device which shall keep it from firing and with a provision against accidental discharge. The markers shall undergo tests for disabling device, accidental discharge, barrel blocking device, and impact, and shall conform to the requirements specified.View Less
