1、Designation: F2574 06 (Reapproved 2010)F2574 06 (Reapproved 2014)An American National StandardStandard Specification forLow Velocity Projectile Marker1This standard is issued under the fixed designation F2574; the number immediately following the designation indicates the year oforiginal adoption or
2、, in the case 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.1. Scope1.1 This specification covers low velocity projectile markers (herein referred to a
3、s LVP marker) that propel a low velocityresilient material projectile (herein referred to as LVRM projectile as defined in Specification F2573) by means of energy releasedby compressed air, compressed gas, or a combination thereof, with velocity not to exceed 53.34 m/s (175 ft/s).1.2 LVRM projectile
4、s are made of a resilient material and have a diameter no smaller than 20 mm (0.7874 in) and no greaterthan 30 mm (1.18 in.). The hardness of the LVRM projectile is to be no greater than 75 Shore 00. The weight of the LVRMprojectile is not to exceed 4.0 g.1.3 The values stated in SI units are to be
5、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 standarddoes not purport to address all of the safety concerns, if any, associated with its use. It i
6、s the responsibility of the user of thisstandard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.2.
