Temperature shock test
As mentioned earlier, rapid changes in
temperature frequently occur near process-
related sources of heat and cold in process
engineering. This test verifies that the
contact quality of the terminal points
remains consistently high even with rapid
temperature changes.
For testing purposes, five terminal blocks
are mounted on the support and wired to a
conductor with the rated cross section. The
structure is subjected to rapid temperature
changes using a two-chamber method. The
temperatures lie close to the upper and
lower limiting temperatures of the terminal
block. This is generally a temperature range
of -55°C to +100°C. The dwell time in each
climatic chamber is 45 minutes, whereby
the change takes place within a few seconds.
This change is performed for 100 cycles.
The requirements are met if, after the
test, the single parts are undamaged and
their further use is guaranteed.
After the terminal block has cooled down to room temperature, it must undergo a
voltage-drop test. Phoenix Contact terminal blocks exhibit consistently good temperature
behavior, thanks to high-quality materials.
