This Technical Specification defines the standard test method to assess the operating mechanical endurance of a set of connectors without electrical load.
This specification covers the requirements for forged bolts in DTD5638, EN 2952, EN 3219 or AMS5662 material with rolled underhead radii. The bolts will develop a minimum tensile strength of 1275 MPa (185,000 lbf/in²) at room temperature and 1000 MPa (145,000 lbf/in²) at 650°C.
