ISO 15614-6:2006(E)
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 15614-6 was prepared by the European Committee for Standardization (CEN) Technical Committee
CEN/TC 121, Welding, 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).

Introduction
ISO 15614 is part of a series of standards. Details of this series are given in ISO 15607:2003, Annex A.
Requests for official interpretations of any aspect of this part of ISO 15614 should be directed to the
Secretariat of ISO/TC 44/SC 10 via your national standards body, a complete listing of which can be found at

INTERNATIONAL STANDARD ISO 15614-6:2006(E)

Specification and qualification of welding procedures for
metallic materials — Welding procedure test —
Part 6:
Arc and gas welding of copper and its alloys
1 Scope
This part of ISO 15614 specifies how a preliminary welding procedure specification is qualified by welding
procedure tests. It applies to the arc and gas welding of copper and copper alloys in all product forms.
This part of ISO 15614 defines the conditions for the execution of 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 part of ISO 15614.
Additional tests may be required by application standards.
The principles of this part of ISO 15614 may be applied to other fusion welding processes.

ISO 15614-6:2006(E)
6 Welding procedure test
The making and testing of test pieces shall be in accordance with Clauses 7 and 8.
The welder or welding operator who undertakes the welding procedure test satisfactorily, in accordance with
this part of ISO 15614, is qualified for the appropriate range of qualification given in ISO 9606-3 or ISO 14732
providing that the relevant testing requirements are met.
7 Test piece
7.1 General
The welded joint to which the welding procedure will relate in production shall be represented by making a
standardized test piece or pieces, as specified in 7.2. Where the production/joint geometry requirements do
not represent the standardized test pieces as shown in this part of ISO 15614, ISO 15613 shall be used.
7.2 Shape and dimensions of test pieces
7.2.1 General
The length or number of test pieces shall be sufficient to allow all required tests to be carried out.
Additional test pieces, or test pieces longer than the minimum size, may be prepared in order to allow for extra
testing and/or for re-testing specimens (see 8.6).
For all test pieces except branch connections (see Figure 5) and fillet welds (see Figure 4), the material
thickness, t, shall be the same for both plates/pipes to be welded.
If required by the application standard, the direction of plate rolling shall be marked on the test piece.
The thickness and/or outside pipe diameter of the test pieces shall be selected in accordance with 9.3.2.1 to
9.3.2.4.
The shape and minimum dimensions of the test piece shall be as given in 7.2.2 to 7.2.6.
7.2.2 Butt joint in plate with full penetration
The test piece shall be prepared in accordance with Figure 1.
7.2.3 Butt weld between plates with raised edges
The test piece shall be prepared in accordance with Figure 2.
7.2.4 Butt joint in pipe with full penetration
The test piece shall be prepared in accordance with Figure 3.
NOTE The word “pipe”, alone or in combination, is used to mean “pipe”, “tube” or “hollow section”.
7.2.5 T-joint
The test piece shall be prepared in accordance with Figure 4.
This may be used for fully penetrated butt welds or fillet welds.
ISO 15614-6:2006(E)
7.2.6 Branch connection
The test piece shall be prepared in accordance with Figure 5. The angle α is the minimum to be used in
production. This may be used for fully penetrated joints (set-on or set-in or set-through joint, and for fillet
welds).
7.3 Welding of test pieces
The preparation and welding of test pieces shall be carried out in accordance with the pWPS, and under the
general conditions of welding in production which they shall represent. Welding positions and limitations for
the angle of slope and rotation of the test piece shall be in accordance with ISO 6947. If tack welds are to be
fused into the final joint, they shall be included in the test piece.
Welding and testing of the test pieces shall be witnessed by an examiner or examining body.
