1.1 本说明书描述了各种性能水平并对其进行分级，以向标准的用户提供选择合适的搭扣和其他附接装置的标准。没有努力纳入国防部或其他高度敏感应用使用的特制搭扣的标准。 1.2 所描述的测试是实验室测试，尽管它们模拟了攻击的现场条件，但它们不会复制这些条件。所述测试在实验室中是可重复的。 1.3 本标准的一些用户可能希望使用具有与安全性无关的特殊属性的搭扣。 1.4 以SI单位表示的值应被视为标准。括号中给出的英寸-磅单位仅供参考。 1.5 本标准并不旨在解决与其使用相关的所有安全性问题（如果有）。本标准的使用者有责任在使用前建立适当的安全、健康和环境实践并确定法规限制的适用性。 1.6 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》中确立的国际公认的标准化原则制定的。

1.1 This specification describes and grades various levels of performance to provide users of the standard with criteria upon which to select suitable hasps and other attachment devices. No effort has been made to include criteria for specially made hasps used by the Department of Defense or other highly sensitive applications. 1.2 The tests described are laboratory tests, and although they simulate field conditions as to attacks, they do not duplicate these conditions. Tests described are repeatable in the laboratory. 1.3 Some users of this standard may wish to use hasps that have special attributes not related to security. 1.4 The values stated in SI units are to be regarded as the standard. The inch-pound units given in parentheses are provided for information only. 1.5 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. 1.6 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.
