本标准规定了测试紧固件的方法，包括SI和I-P单位，以确定其物理和机械性能。在适用文件中特别提及时，应遵守这些标准试验方法。如果这些方法的规定与特定项目规范中的单独试验程序之间存在冲突，应以后者为准。本文件作为动态标准存在，可根据“最新技术”进行添加和更改

This standard establishes methods for testing fasteners, covering both the SI and I-P units, to determine their physical and mechanical properties. These standard test methods shall be observed when specifically referenced in the applicable documents. In case of conflict between the provisions of these methods and the individual test procedure in the specification for a particular item, the latter shall take precedence. This document exists as a dynamic standard subject to addition and changes as reflected by the "state-of-the-art."
