Destructive tests on welds in metallic materials - Cold cracking tests for weldments - Arc welding processes - Part 2: Self-restraint tests (ISO 17642-2:2005)
This standard specifies the sizes of the test pieces, the specimens and the procedures for carrying out selfrestraint 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 standard applies primarily but not exclusively to C-Mn and low alloy steels.
