Abstract / scope

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.
