ISO 17642-2:2005 specifies the sizes of the test pieces, the specimens and the procedures for carrying out self-restraint cold cracking tests by:
- CTS (controlled thermal severity) test
- Tekken (Y-groove) or Lehigh (U-groove) test
in order to obtain information about the cold cracking sensitivity during welding.
This International Standard applies primarily, but not exclusively, to C-Mn and low-alloy steels.
