Abstract / scope
The document specifies requirements for the approval testing of welding procedures for the arc-welding of tube to tube-plate joints in metallic materials by manual, semiautomatic, automatic or mechanized processes. It is a part of a series of standards given in ISO 15607. Annex B gives details of these standards. Approval by tube to tube-plate joints tests can be used for all joints even if they are fully loaded or only seal welded as required in application standards.
