Additional testing
Torque test
During this test, the lid, gland plate screws and earthing
screws are all tightened and loosened from the enclosure
using the torque recommended by the manufacturer. This is
repeated ve times.
If the torque value required to destroy a rivet or shear off
a bolt is greater than the specied torque, then the test is
considered passed.
Vibration and shock testing
The enclosures can be exposed to extreme vibrations and
oscillations during use. The vibration and shock test can
determine how much vibration an enclosure can withstand.
The steel and aluminium enclosures are mainly tested for
railway requirements and compliance with DIN EN 61373.
Computed tomography (CT)
Using computer tomography, we can create two-dimensional
radiographic images and volume models of the enclosures to
assist us in the development stage. This allows us to see the
welded joints and immediately identify any potential leakage
areas without using any destructive tests.
This process is used on the Klippon
®
TB enclosures to nd
any possible leaks around the welded inner-thread sockets
(refer to page 17 “Attaching the inner-thread sockets”).
Light resistance test (sun test)
The light resistance test is used to check the UV resistance
of plastic enclosures. In this test, the enclosures are
subjected to a beam of simulated sunlight for 168 hours
which corresponds to daylight phase D 65 according to CIE.
After the radiation exposure, the enclosures are inspected
for cracks and colour changes, and are compared with an
untested enclosure. If no differences, no colour changes and
no cracks can be detected on the enclosures, then the test
has been passed.
