14、iiiForeword ISO (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 which
15、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 matt
16、ers of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circul
17、ated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this part of ISO 15614 may be the subject of patent rights. ISO shall not be held
18、responsible for identifying any or all such patent rights. ISO 15614-8 was prepared by the European Committee for Standardization (CEN) in collaboration with ISO Technical Committee TC 44, Welding and allied processes, Subcommittee SC 10, Unification of requirements in the field of metal welding, in
19、 accordance with the Agreement on technical cooperation between ISO and CEN (Vienna Agreement). Throughout the text of this standard, read “.this European Standard.“ to mean “.this International Standard.“. ISO 15614 consists of the following parts, under the general title Specification and qualific

29、 given the status of a national standard, either by publication of an identical textor by endorsement, at the latest by October 2002, and conflicting national standards shall be withdrawn at thelatest by October 2002.This document has been prepared under a mandate given to CEN by the European Commis
30、sion and theEuropean Free Trade Association, and supports essential requirements of EU Directive(s).Annex A is informative. Annex ZA is normative.According to the CEN/CENELEC Internal Regulations, the national standards organizations of the followingcountries are bound to implement this European Sta

32、eemailing clients of the SABS .ISO 15614-8:2002(E) ISO 2002 All rights reserved 11 ScopeThis European Standard specifies requirements for the qualification testing of welding procedures for the arcwelding of tube to tube-plate joints in metallic materials by manual, partly mechanized, mechanized or
33、automaticprocesses.This standard is a part of a series of standards. Details of this series are given in prEN 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 sealwelded as required in application standards.In such ca
34、ses, one or more special test pieces should be made to simulate the production joint in all essentialfeatures, e.g. dimensions, restraint, heat sink effects. The test should be carried out prior to and under theconditions to be used in production.This standard applies to fusion welding of metallic m
35、aterials for tube to tube-plate joints with gap. This standarddoes not apply to tube-sheets with forged end connections with welded tubes (external/internal bore welds). Forwelding of tube to tube-plate joints without gap welding procedure test should be defined in the specification.For other applic
36、ations and/or requirements the standard can be used if required by the specification.Repair welding should be considered in the welding procedure test.2 Normative referencesThis European Standard incorporates by dated or undated reference, provisions from other publications. Thesenormative reference
