Tested down to the details
The test is passed when the enclosure is still able to
maintain its IP degree and when the lid can be removed and
reattached after the test.

Metal enclosures must ensure electrical continuity, either
using the conductive parts of the enclosure, or using a
separate protective earth conductor, or by using both.
The Klippon
®
TB enclosures provide sufcient earthing
options to ensure this continuity: a self-locking M10 earth
bolt on the bottom enclosure section and two additional M6
earth screws in the lid and bottom.
The contact resistance of the enclosures is measured with a
current of 10 A DC.
The measuring current is fed in via the outer PE and the
bottom of the enclosure.
The PE connection must remain under the required limit of
100 mΩ liegen.
Salt spray corrosion test (proves corrosion
resistance)
Enclosures are often used outdoors where they can come
into contact with rain or sea water. It is critical to determine
that the enclosures are (and will continue to be) resistant to
corrosion for these types of applications.
In order to simulate such a scenario, a corrosion test is
carried out on the enclosure where it is subjected to a salt
water mist. This is used to indicate weak points, pores or
damage to the surface.
In this test, the enclosures are placed in a humid atmosphere
(40 °C and 95 % humidity). They are then sprayed with a
salt water mist for over 336 hours in accordance with DIN
ENISO 9227.
After this exposure, the enclosure is rinsed off for 5 minutes
so that any evidence of corrosion can be precisely identied.
The test is passed if no formation of red rust is found on the
enclosure.
Durability of markings
All labels on the enclosure must be tested for their wipe
resistance. One test using water and one test using mineral
spirits is conducted.
The test is passed when the labelling can still be easily read.
Upon request by the customer, the wipe resistance test can
be carried out with other chemicals and solvents for ATEX
and ICEX Type lable.
