Note: In the event of conflict between the Korean and En
3、glish language, the Korean language shall take precedence. 1.1 Purpose. This standard aims at helping test personnel perform the test in an appropriate method by describing the measuring method of permanent strain when applying the stress to the bolt under a specified load less than yield stress (st
4、ress at permanent set limit Rp0.2). 1.2 Applicability. This standard specifies the method of proof load test for external thread parts Note 1 such as bolts and screws. Note 1: The thread of the bolt shall be 4 mm or more in nominal diameter (D), and 3D or more in length. 2 References Note: Only the
