Introduction
All new welding procedure tests are to be carried out in accordance with this document from the date
of its issue. However, this document does not invalidate previous welding procedure tests made to
former national standards or specifications or previous issues of this document.
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 which should be made in accordance with this
document.

Additional test pieces, or longer test pieces than the minimum size, may be prepared in order to allow
for extra and/or for re-testing specimens (see 7.7).
For all test pieces, except branch connections (see Figure 4) and fillet welds (see Figure 8), the material
thickness, t, shall be the same for both plates/pipes to be welded.
The thickness and/or outside pipe diameter of the test pieces shall be selected in accordance with
8.3.2.1 to 8.3.2.4.
The shape and minimum dimensions of the test pieces shall be as follows:
6.2.2 Butt joint in plate with full penetration
The test pieces shall be prepared in accordance with Figure 1.
6.2.3 Butt joint in pipe with full penetration
The test pieces shall be prepared in accordance with Figure 2.
NOTE The word “pipe”, alone or in combination, is used to mean “pipe”, “tube” or “hollow section” except
square or rectangular hollow section.
6.2.4 T-joint
The test pieces shall be prepared in accordance with Figure 3. These may be used for fully penetrated
butt welds or fillet welds.
6.2.5 Branch connection
The test pieces shall be in accordance with Figure 4. The angle α is the minimum to be used in
production. These may be used for fully penetrated joints (set-on or set-in or set-through joint) and for
fillet welds.
6.3 Welding of test pieces
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

7 Examination and testing
7.1 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, e.g.:
— longitudinal weld tensile test;
— all weld metal bend test;
— hardness test;
— impact test;
— corrosion test;
— chemical analysis.
NOTE Specific service, material or manufacturing conditions may require more comprehensive testing than
specified by 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.

Tests as detailed do not provide information on the mechanical properties of the joint. Where these properties are
relevant to the application an additional qualification shall also be held, e.g. a butt weld qualification.
7.2 Location and taking of test specimens
Test specimens shall be taken in accordance with Figures 5, 6, 7 and 8.
Test specimens shall be taken after all non-destructive testing (NDT) has been carried out and which
has passed the relevant acceptance criteria for the NDT method(s) used.
It is acceptable to take the test specimens from locations avoiding areas which have imperfections
within the acceptance limits for the NDT method(s) used.
