a) Two additional welds of the same batch shall be examined by the same method(s);
b) If these additional welds are acceptable, the initial weld shall be repaired or replaced and re-examined by
the original method(s);
c) If any one of these additional welds required by a) reveal an unacceptable imperfection, two further
additional welds of the same batch shall be examined by the same method(s).
d) If the two additional welds required by c) are acceptable, the initial weld and the weld(s) examined under
c) with unacceptable imperfections shall be repaired or replaced and re-examined by the original
method(s).
e) If any one of the two additional welds required by c) reveal an unacceptable imperfection, all welds in that
batch shall be examined and, as necessary, repaired or replaced and re-examined.
8.2 Circumferential butt, branch, fillet and seal welds
8.2.1 Extent of testing
The type of NDT required and its extent shall be determined in accordance with Table 8.2-1, taking into
account the category the piping is classified to and also wall thicknesses and material grouping.
For piping where creep or fatigue is the controlling factor in design:
a) additional extent of NDT is required by Table 8.2-1, Note f, critical areas shall be included in the test;
b) the quality level given in Table 8.4.2-1 for these service conditions shall be met.
For piping of pipe category 0 and piping operating at or below 0,5 bar the amount of NDT shall be suitable to
assure weld quality. For volumetric testing a minimum amount of 2% is recommended. When pneumatic testing
is used, the extent of testing according to Table 9.3.3-1 applies. When agreed in the purchase order, for piping of
category I made of material of material group 1.1, 1.2 and 8.1 an amount of 2% volumetric testing may be
sufficient, if satisfactory experience exists.

prEN 13480-5:2011 (E)
7.3.2 Inspection of welding set-up
Prior to carrying out any welding, each weld preparation shall be visually inspected. The inspection shall verify
compliance with the drawing and WPS, by ensuring the following:
the correct materials are used;
dimensions are within tolerance, including position, alignment, and orientation of branches, nozzles,
attachments and anchors, etc.;
cleanliness and freedom from imperfections which may give rise to defects in the completed joint;
nozzles, branches etc., properly fit the curvature of the pipe;
tack welds that are to be incorporated into the final weld are free from cracks or other defects.
7.3.3 Testing and inspection during welding
The following testing and inspection shall be carried out, where appropriate, at suitable stages during the
welding operation to verify that the specified WPS is being followed for:
a) correct preheat;
b) correct welding process;
c) correct welding consumables;
d) correct electrical characteristics;
e) correct interpass temperature and cleaning;
f) other requirements of the WPS;
g) all tack welds and temporary attachments are welded in accordance with an approved WPS.
7.3.4 Inspection after welding
The following inspection shall be carried out on completion of welding:
a) examination for compliance with drawings;
b) verification that welds are correctly identified and traceable to the welder/operator;
c) verification that temporary attachments have been properly removed.
7.4 Heat treatment
For post-forming and post-weld heat treatment (PWHT), where applicable, it shall be verified by a review of
the heat treatment reports, that the heat treatment carried out complies to the heat treatment procedure.
If additional examinations (e.g. replica, hardness) after post-forming and post-weld heat treatment are
required, this testing shall be reported and the reports shall be reviewed.

8 Non-destructive testing of welds
8.1 Application of NDT
8.1.1 General
8.1.1.1 The following shall be applicable to all welded joints:
a) welded joints shall be visually examined before any other NDT is performed;
b) the area to be examined shall include the weld metal and the heat affected zones;
c) surface examination stipulated in Table 1 shall be performed on the outer surface;
d) where a welded joint is to be subsequently formed or heat treated, the required NDT shall be carried out
on the weld in the final condition. If a weld will not be accessible for examination after heat treatment or
forming, the parties involved shall agree on a suitable alternative;
e) NDT-method used and acceptance criteria for all NDT shall be in accordance with 8.4.5;
f) weld imperfections, which have been assessed as weld defects, shall be repaired in accordance with
EN 13480-4:2002 and inspected again after repair.
8.1.1.2 Arc strikes and contact points with fused material shall be ground smooth and subjected to
surface examination appropriate to the material used.
8.1.1.3 Regarding the surface condition and preparation for non-destructive testing the criteria specified
in the testing standards referenced in EN ISO 17635:2010 apply.
NOTE Care should be taken to avoid masking of flaws by any surface dressing process.

8.1.2 Examination of weld quality by sample inspection
Where the required extent of non-destructive testing is less than 100 %, the specified NDT techniques shall be
employed at the earliest stage practicable in the fabrication process to ensure that sound welds are achieved.
The timing shall be agreed between the parties involved. Sample joints to be examined shall be:
randomly selected;
representative of a group of welds.
At least one complete sample joint shall be examined over the whole circumference of the joint.
Where the number of sample joints required is small, combinations of thicker sections and smaller diameters
or thinner sections and greater diameters shall be given preference.
NOTE A group of welds is a quantity of welds, welded by one welder or welding operator, in accordance with a
specific welding procedure specification.
8.1.3 Imperfections revealed by sample inspection
When sample inspection reveals imperfections in one weld which are not acceptable to this European Standard,
the following shall apply for each defective weld:
a) Two additional welds of the same group shall be examined by the same method;
b) If these additional welds are acceptable, the initial weld shall be repaired or replaced and re-examined by
the original method;
c) If any one of these additional welds required by a) reveal an unacceptable imperfection, two further
additional welds of the same group shall be examined by the same method.
d) If the two additional welds required by c) are acceptable, the initial weld and the weld(s) examined under
c) with unacceptable imperfections shall be repaired or replaced and re-examined by the original method.
e) If any one of the two additional welds required by c) reveal an unacceptable imperfection, all welds in
that group shall be examined and, as necessary, repaired or replaced and re-examined.
8.2 Circumferential butt, branch, fillet and seal welds
8.2.1 Amount of examination
The type of NDT required and its extent shall be determined in accordance with Table 1, taking into account
the category the piping is classified to and also wall thicknesses and material grouping.
For piping where creep or fatigue is the controlling factor in design,
additional extent of NDT is required by Table 1 Note f and
the quality level given in Table 3 for this service conditions shall be met.
For piping of pipe category 0 and piping operating ≤ 0,5 bar the amount of NDT shall be suitable to assure weld
quality. For volumetric testing a minimum amount of 2% is recommended.
When agreed in the purchase order, for piping of categoryI made of material of material group 1.1, 1.2 and 8.1
an amount of 2% volumetric testing may be sufficient, if satisfactory experience exists.
