1.1 本规范涵盖了由弹性材料制成的低速弹性材料弹丸（以下简称LVRM弹丸）的关键特性，其直径不得小于20 mm（0.7874 in.），不得大于30 mm（1.18 in.），硬度不得大于75邵氏00，符合规范 D2240型 本规范有助于确定弹丸是否适用于低速弹丸标记（以下简称为规范中定义的LVP标记 2574层 ). LVRM弹丸的重量不得超过4.0 g。此外，本规范规定了最低警告和包装标签，以帮助确保LVRM弹射物以安全的方式使用，并降低受伤风险。 1.2 LVRM弹丸不是规范第2.1.2节中定义的彩弹 1979财年 . 1.3 以国际单位表示的数值应视为标准值。括号中给出的值仅供参考。 1.4 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 critical characteristics of low velocity resilient material projectiles (herein referred to as LVRM projectiles) made of a resilient material, and shall have a diameter no smaller than 20 mm (0.7874 in.) and no greater than 30 mm (1.18 in.), with a hardness no greater than 75 Shore 00 in accordance with Specification D2240 . This specification helps define whether a projectile is suitable for use with a low velocity projectile marker (herein referred to as LVP marker as defined in Specification F2574 ). The weight of the LVRM projectile is not to exceed 4.0 g. Furthermore, this specification establishes minimum warning and package labeling to help ensure that the LVRM projectiles are used in a safe manner and that the risk of injury is reduced. 1.2 A LVRM projectile is not a paintball as defined in Section 2.1.2 of Specification F1979 . 1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only. 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, 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.
