标准摘要
[中文适用范围]： 本文件描述了螺纹型盲孔紧固件的锁紧扭矩测试方法。 本试验方法用于测量带内螺纹和外套筒的盲孔紧固件的锁紧扭矩。 它适用于由四个元件（驱动螺母、螺母、套筒和芯螺栓）组成的盲孔紧固件，螺母顶部有十字槽。 [外文原描述]： This document describes the locking torque test method for blind fasteners, threaded type. This test method is used to measure the locking torque of blind fasteners with internal thread and external sleeve. It is applicable to blind fasteners consisting out of four elements (drive nut, nut, sleeve and corebolt) having a cross recess at the top of the nut.
