28、:2016(E)ForewordISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for wh
29、ich a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all
30、matters of electrotechnical standardization.The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents should be noted. This
31、 document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or a
32、ll such patent rights. Details of any patent rights identified during the development of the document will be in the Introduction and/or on the ISO list of patent declarations received (see www.iso.org/patents).Any trade name used in this document is information given for the convenience of users an

However, this part of ISO 15614 does not invalidate previous welding procedure tests made to former national standards or specifications
40、 or previous issues of this part of ISO 15614.

41、ecifies requirements for the qualification testing of welding procedures for the arc welding of tube to tube-plate joints in metallic materials by manual, partly mechanized, fully mechanized, or automatic processes.This part of ISO 15614 is a part of a series of standards. Details of this series are
42、 given in ISO 15607, Annex A.Qualification by tube to tube-plate joint tests can be used for all joints even if they are fully loaded or only seal welded as required in application standards.This part of ISO 15614 applies to fusion welding of metallic materials for tube to tube-plate joints with a r
43、emaining gap between the tube and the tube-plate for some length of the tube-plate thickness. This part of ISO 15614 does not apply to tube-sheets with forged end connections with welded tubes (external/internal bore welds).For welding of tube to tube-plate joints with mechanical expansion which is
44、load bearing, welding procedure test is to be defined.For other applications and/or requirements, this part of ISO 15614 can be used if required by the specification.Repair welding is to be considered in the welding procedure test.2 Normative referencesThe following documents, in whole or in part, a
