DANSK DSF/PREN ISO 15614-6 [ Draft ]

This document specifies how a preliminary welding procedure specification is qualified by welding procedure tests. It applies to arc and gas welding of copper and copper alloys in all product forms. This document defines the conditions for the execution of welding procedure tests and the range of qualification for welding procedures for welding operations within the range of variables listed in Clause 9. This document is applicable to all new welding procedures. However, it does not invalidate previous welding procedure tests made to former national standards or specifications. Where additional tests have to be carried out to make the qualification technically equivalent, it is only necessary to do the additional tests on a test piece made in accordance with this document. Additional tests can be required by application standards. The principles of this document may be applied to other fusion welding processes.
