- Scope
- This standard specifies the torsion test method for wire used for rivet contacts. This standard is suitable for testing the performance of wires used for rivet contacts and other wires used in contacts to withstand plastic deformation when twisted in one or alternating directions, and to show metal inhomogeneity, surface defects and some internal defects.
