1.1 本规范涵盖用于提高空载枪支安全性的非整体锁定装置。 1.2 本规范包含非整体式枪支锁定装置的功能、操作和安全要求。包括第节中规定的功能描述、力测试和秘密进入测试 5. . 1.3 本规范旨在仅适用于应用于枪支、在枪支内、周围或周围的非整体锁或锁定机制，无论是在枪支外部，还是通过某种方法引入枪支或在枪支内。 本规范无意设定评估标准，根据这些标准评估安全杆、撞针块或其他传统放电预防机制，尽管这些机制可能会防止意外放电。本规范不适用于用于或旨在防止盗窃或其他故意滥用枪支的装置。 注1: 所述测试为实验室类型测试，尽管它们可能模拟一些现场条件，但并不复制所有现场测试条件。 注2: 没有明显可比的ISO/IEC标准。 1.4 以国际单位制表示的数值应视为标准值。括号中给出的值仅供参考。 1.5 以下预防性警告仅适用于本规范的试验方法部分。 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全和健康实践，并确定监管限制的适用性。

1.1 This specification covers non-integral locking devices used to increase safety on unloaded firearms. 1.2 This specification contains functional, operational, and safety requirements for non-integral firearm locking devices. Included are function descriptions, force tests, and surreptitious entry tests as set forth in Section 5 . 1.3 The specification is intended to apply only to non-integral locks or locking mechanisms applied to, in, around, or about a firearm, either external to the firearm or by some method of introduction to or within the firearm. The specification is not intended to set evaluation standards by which safety levers, firing pin blocks, or other traditional discharge prevention mechanisms are evaluated, notwithstanding the fact that these mechanisms may prevent inadvertent discharge. This specification is not applicable to devices used for, or intended for, the prevention of theft or other intentional misuse of firearms. Note 1: Tests described are laboratory type tests and although they may simulate some field conditions, they do not duplicate all field test conditions. Note 2: There is no apparent comparable ISO/IEC standard. 1.4 The values stated in SI units are to be regarded as standard. The values given in parentheses are for information only. 1.5 The following precautionary caveat pertains only to the test method portions 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.
