NF EN ISO 17642-2
Destructive tests on welds in metallic materials - Cold cracking tests for weldments - Arc welding processes - Part 2 : self-restraint tests
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.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.
The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.
