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 the European Committee for Standardization (CEN) Technical Committee

1 Scope

This part of ISO 15614 specifies how a preliminary welding procedure specification (pWPS) for production and

repair welding of non-alloyed and low-alloyed cast irons is qualified by fusion welding procedure tests.

This part of ISO 15614 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 a defined list of

variables.

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 part of ISO 15614.
Additional tests may be required by application standards.

This part of ISO 15614 is applicable to welding non-alloyed and low-alloyed grey cast iron castings according

to: EN 1561; EN 1562; EN 1563; and EN 1564.

The principles of this part of ISO 15614 are also applicable for welding cast iron to steel or to other unalloyed

and low-alloyed cast iron materials.

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

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.
