The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which 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 matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated 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 document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 15612 was prepared by the European Committee for Standardization (CEN) in collaboration with Technical Committee ISO/TC 44, Welding and allied processes, Subcommittee SC 10, Unification of requirements in the field of metal welding, in accordance with the Agreement on technical cooperation between ISO and CEN (Vienna Agreement). This first edition of ISO 15612 cancels and replaces ISO 9956-7:1995, of which it constitutes a technical revision.

This standard gives the manufacturer the possibility to use welding procedures based on welding procedure tests performed by other organisations. This standard is a part of a series of standards, details of this series are given in EN ISO 15607:2003, annex A. The use of this standard can be restricted by an application standard or a specification. 2 Normative references The following referenced documents are indispensable for the application of this document.

This pWPS shall specify the range for all the relevant parameters. 5 Qualification by adoption of the standard welding procedure 5.1 General The qualification of the welding procedure shall be carried out by an examiner or an examiner body according to EN ISO 15607. It shall be verified that examination and testing have been carried out in accordance with the appropriate part of EN ISO 15614. After qualification, the preliminary welding procedure specification will be considered as a standard welding procedure specification. Changes outside the range of qualification given in the appropriate part of EN ISO 15614 as modified in 5.2 shall require a new qualification welding procedure. The welding procedure shall be qualified by the manufacturer and if applicable, verified by an examiner or examining body in accordance with EN ISO 15607. 5.2 Parent metal This standard is applicable for parent material groups defined in Table 1.

The use of a standard welding procedure requires welding coordination in accordance with EN 719 and that the user fulfils quality requirements in accordance with the appropriate part of EN 729. 6.3 Related to the welding equipment The standard welding procedure is qualified for use in production with welding power sources and welding equipment having electrical and mechanical characteristics which are capable of achieving those used in preparing the test weld for qualification of the standard welding procedure as specified in the welding procedure specification WPS. The equipment used during production shall permit control of all essential welding parameters. 6.4 Related to the personnel A standard welding procedure shall only be used by welders or welding operators for mechanized equipment qualified in accordance with the relevant part of EN 287 or EN ISO 9606 or EN 1418.
