ISO/DIS 15614-3
Foreword
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 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 15614-3 was prepared by Technical Committee ISO/TC 44, Welding and allied processes, Subcommittee
SC 10, and by Technical Committee CEN/TC 121, Welding in collaboration.
ISO 15614 consists of the following parts, under the general title Specification and qualification of welding
procedures for metallic materials — Welding procedure test:
⎯ Part 1: Arc and gas welding of steels and arc welding of nickel and nickel alloys
⎯ Part 2: Arc welding of aluminium and its alloys
⎯ Part 3: Arc welding of cast irons
⎯ Part 4: Finishing welding of aluminium castings
⎯ Part 5: Arc welding of titanium, zirconium and their alloys
⎯ Part 6: Copper and copper alloys
⎯ Part 7: Overlay welding
⎯ Part 8: Welding of tubes to tube-plate joints
⎯ Part 9: Underwater hyperbaric wet welding
⎯ Part 10: Hyperbaric dry welding
⎯ Part 11: Electron and laser beam welding
⎯ Part 12: Spot, seam and projection welding
⎯ Part 13: Flash and butt welding

ISO/DIS 15614-3
Introduction
This standard is a part of a series of standards, details of this series are given in EN ISO 15607:2003, Annex A.
Welding procedure tests for flash welding are presented in EN ISO 15614-13 and for friction welding in EN ISO
15620.
Requests for official interpretations of any aspect of this standard should be directed to the secretariat of ISO/TC
44/SC 10 via your national standards body, a complete listing whivh can be found at www.iso.org.
1 Scope
This Standard specifies how a preliminary welding procedure specification for production and repair welding of non-
alloyed and low-alloyed cast irons is qualified by welding procedure tests. It applies to fusion and pressure welding.
This standard defines the conditions for execution of the welding procedure tests and the range of qualification for
welding procedures for all practical welding operations within the range of variables listed in clause 9.
This part of ISO 15614 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 standard.
Additional tests may be required by application standards.
This Standard is applicable to welding Grey cast irons of non-alloyed and low-alloyed cast iron castings according
to:
⎯ EN 1561 Founding;
⎯ EN 1562 Founding – Malleable cast irons;
⎯ EN 1563 Founding – Spheroidal graphite cast irons;
⎯ EN 1564 Austempered ductile cast irons;
The principles of this standard are also applicable for welding cast iron to steel or to other unalloyed and low-alloyed
cast iron materials.
2 Normative references
This European Standard incorporates by dated or undated reference, provisions from other publications. These
normative references are cited at the appropriate places in the text and the publications are listed hereafter. For
dated references, subsequent amendments to or revisions of any of these publications apply to this European
Standard only when incorporated in it by amendment or revision. For undated references the latest edition of the
publication referred to applies.
