6.1.2 Indirect tests
Generally, testing shall be performed according to the test method referred to EN 1796, EN 14364 and

testing shall not be applied to type testing.
The correlation or safe relationship of the indirect testing to the specified testing shall be documented in the
manufacturer's quality plan. If a third party certification is involved, the IT shall be accepted by the certification
body. The continuing validity of the indirect testing shall be checked at regular intervals. In cases of dispute,

Type tests shall be conducted in accordance with the requirements and rules given in Annex A and, the
requirements given in 6.2.2 to 6.2.4, as applicable.
6.2.2 Pipe type test group
A pipe type test group consists of a range or family of products made such that the results of the long-term
type tests are applicable to all products in the group. A pipe type test group shall be made of products:
a) manufactured by the same process;
b) with the same material specifications;
c) with the same pipe wall construction (i.e. the sequence of layers, layer compositions, material properties
and design method for using the results of the long-term type tests in determining the pipe wall for all
combinations of DN, PN and SN);
d) tested with the same loading condition (i.e. uniaxial or biaxial load).
The quality management system shall document all process details that could influence type test
performance. The quality management system shall document the complete product design method and
demonstrate how the results of the type tests are used to establish product designs.

6.2.3 Joint type test group
6.2.3.1 General
A joint type test group is determined by the configuration of the joint and the loading condition. Joint type test
groups are the following:
a) flanged uniaxial loading;
b) flanged biaxial loading;
c) butt/wrap uniaxial loading;
d) butt/wrap biaxial loading;
11

---------------------- Page: 13 ----------------------

SIST-TS CEN/TS 14632:2012
CEN/TS 14632:2012 (E)
e) cemented uniaxial loading;
f) cemented biaxial loading;
g) gasket sealed uniaxial loading;
h) gasket sealed biaxial loading.
NOTE The term “uniaxial loading” refers to pressurization where there is no pressure end thrust component (the
pressure end thrust is taken by the test fixture and not the pipe) and thus the pipe is loaded only in the circumferential
direction while “biaxial loading” refers to pressurization where the pressure end thrust component is carried by the pipe
and thus the pipe is loaded in both circumferential and longitudinal directions.
The joint testing methods give the performance requirements for the various configurations of joints, but
recognizing the very wide range of diameters and pressures it is clearly impractical to test all combinations of
DN/PN. The quality management system shall document the procedures for designing and manufacturing the
joints and include the results of testing programs to verify performance and establish over what range the test
results are applicable and how the design procedures are established and how they apply across the product
range. It is likely that multiple tests will be required to qualify the full range of PN and DN for any given
combination of joint configuration and loading condition and these results shall be documented as part of the
quality management system.
6.2.3.2 Butt/wrap and cemented joints
For butt/wrap and cemented joints, the methodology for designing joints shall be established by conducting
type tests that can be used to establish the procedures for design of the complete range of joints. Butt/wrap
and cemented joints are evaluated according to
...
