1.1 本规范涵盖了推进低速弹性材料弹丸（本规范中定义为LVRM弹丸）的低速弹丸标记（以下简称LVP标记） 2573层 )通过压缩空气、压缩气体或其组合释放的能量，速度不超过53.34m/s（175ft/s）。 1.2 LVRM弹丸由弹性材料制成，直径不小于20 mm（0.7874 in.），不大于30 mm（1.18 in.）。LVRM弹丸的硬度不得大于75邵氏硬度00。 LVRM弹丸的重量不得超过4.0 g。 1.3 以国际单位表示的数值视为标准值。括号中给出的值仅供参考。 1.4 以下预防性警告仅适用于试验方法部分，第节 8. 本规范中的。 本标准并不旨在解决与其使用相关的所有安全问题（如有）。本标准的使用者有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 1.5 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。

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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
