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.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives).

DRAFT INTERNATIONAL STANDARD ISO/DIS 15614-6:2021(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 document specifies how a preliminary welding procedure specification is qualified by welding
procedure tests. It applies to arc and gas welding of copper and copper alloys in all product forms.
This document defines the conditions for the execution of welding procedure tests and the range of
qualification for welding procedures for welding operations within the range of variables listed in
Clause 9.
This document 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 document.
Additional tests can be required by application standards.
The principles of this document may be applied to other fusion welding processes.

The welded joint to which the welding procedure will relate to in production shall be represented by
making a standardized test piece or test pieces, in accordance with 7.2. Where the production/joint
geometry requirements do not represent the standardized test pieces as shown in this document,
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”.

7.2.6 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 full penetration 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.

8.1 Extent of testing
Testing includes both non-destructive testing (NDT) and destructive testing which shall be in
accordance with the requirements of Table 1.
An application standard may specify additional tests which may include:
— longitudinal weld tensile test;
— all-weld metal bend test;
— corrosion tests;
— chemical analysis;
— hardness test.
NOTE Specific service, material or manufacturing conditions may require more comprehensive testing than
is specified in this document, in order to gain more information and to avoid repeating the welding procedure
test at a later date just to obtain additional test data.
