Reliable and time savingIptDataLogging®
How does one perform an effi cient quality control of the
quality control? Who counter-checks the test run if no-one
is there or many tests are performed simultaneously?
In combination with IPT’s specialized software IptDataLogging®
you are in command of a test manager which continuously
performs quality control, 24 hours, automatically monitors and
records the ongoing procedures.
The software supervises the correctness of the data through-
out the complete test duration, constantly, reports, dis-
plays events and, if requested, forwards you the information
per email or SMS. Due to this self-control and diagnostic, mal-
functions can be recognized quickly and unnecessary costs
caused by test repetitions can be minimized.

PE is soluble just in boiling xylene. But if the PE is cross-
linked, even the boiling xylene can not be able to solve it.
This specifi cation is used for the determination of
degree of crosslinking in PEX pipes. A sample of PEX-
AL-PEX pipe is placed in boiling xylene and the value of
crosslinking is determined based on the percentage of the
sample which remains insoluble in the xylene (PE material
which is not cross-linked is dissolved).
In order to reach the best physical and mechanical spe-
cifi cations for PEX-AL-PEX pipe, a degree of crosslin-
king of between 60 and 70 % (depending upon the type
of material) is required.

This procedure is utilized to prove that the adhesive
which is applied as an intermediate is capable of holding
materials (layers) together by surface attachment.
A PEX-AL-PEX pipe sample is inserted into the cutting device
and rotated to form the spiral cut. The cut goes through
the complete wall on one side of the pipe only. The spiral
cut continues along the pipe for a minimum distance along
the axis equal to fi ve times the outside diameter and then
straightened to a ribbon. After this, the sample can be
visually examined for signs of delamination.

This is a further test for determination of adherence
between the PEX layers and the aluminium.
The test procedure is as follows:
n With a tensile tester and a constant speed, the outer PEX
layer and the aluminium is peeled from the inner PEX layer.
n The pipe is held on a roller mechanism and the outside layers
are clamped to upper grips.
n After peeling, the outer layers can be examined visually for
delamination.

This test is performed to examine the tensile strength
of the pipe and the quality of the weld along the seam
of the aluminium layer.
The sample is a ring from the pipe which is mounted onto
2 steel rods which are separated at a constant speed until
failure and the maximum load is recorded. A failure should
not occur along the weld.

The major test which can assure the pipes life time is
the hydrostatic pressure test.
The test is used to examine a polymer creep behaviour
and is the basis on which the pressure rating, required di-
mensions or anticipated service life of pipes (over 20 years
at 80 °C) can be determined. These tests are performed at
temperatures between 82 °C and 95 °C, depending upon the
standards.
The hydrostatic pressure test is also performed on
PEX-AL-PEX Pipes at 110 °C over 8760 hr to examine
the thermal stability.

The pipe samples are conditioned in a controlled temperture
environment. A continuously increasing internal hydraulic
pressure is applied, either to failure or to a predetermi-
ned load. The predetermined pressure (or failure) must be
reached within 60 – 70 seconds. This test can supply fast
information on the pressure resistance of products under
the respective conditions.

Thermal Cycling Test to EN 12293Model No. 1769/1770

The most signifi cant quality test on hot and cold water
systems is thermal cycling. This test involves all parts
of the pipe assembly, such as pipes, fi ttings, joints and
welds and can confi rm the appropriate design of the
components, raw materials, manufacturing process and
installation procedure. The test shows if changes in tem-
perature will loosen mechanical joints due to differences in
the coeffi cient of thermal expansion between metal mecha-
nical fi ttings and the plastic pipes. For the total system 5000
thermal cycles are completed with the temperature changing
between 20 °C and 95 °C every 15 minutes, and with the
system under test having an internal pressure (depending
upon standard) maintained at max. 10 bar. The total system
passes the test if no leaks are detected.

Dynamic Pressure to EN 12295Model No. 1607–1609/1766
Hot and cold water pipe systems may be subjected to
pressure fl uctuations. The dynamic pressure test is used
to determine a performance capability under fl uctuations
within a pipe system.
According to EN 12 295 and DVGW 534 a test assembly
of pipes and fi ttings is subjected to internal water pressure
cycling between two positive pressure points. The pipe
assembly should be capable of withstanding the test
conditions without leakage. The EN standard requires
performing tests between 0.5 and 25 bar.

Vacuum Test to EN 12294Model No. 1715
Specifi es a method for testing the leak tightness under
vacuum of joints for thermoplastics piping systems. It is
applicable to piping systems based on thermoplastics
pipes intended to be used in hot and cold water pressure
applications.
A test assembly of pipes and fi ttings is subjected to a
partial vacuum over a defi ned period of time. After isola-
ting the sample from the vacuum source, a possible increase
of pressure in the sample is monitored and recorded over
a period of one hour. The pressure increase in the pipe
assembly shall be not greater then 0.05 bar.

Pull-Out Test to EN 712Model No. 1652
This standard specifi es a method for checking the ability
of assembled end-load bearing mechanical joints
(excluding fusion-welded joints) between fi ttings and
pressure pipes to withstand a longitudinal tensile force.
The assembly consisting of fi tting and pipe is subjected to
the calculated, constant pull-out force in a controlled tempe-
rature environment.

Leaktightness Test to EN 713Model No. 1730
This standard specifi es a method for checking the leak
tightness under internal hydrostatic pressure of assem-
bled mechanical joints (excluding fusion-welded joints)
between fi ttings and polyolefi n pressure pipes while
subjected to bending.
The sample (as shown in EN 713) is subjected to an internal
pressure which varies according to the application class, for
a period of one hour at 20 °C, during which no leakage is
allowed.
