electrical resistance the clamping unit has
not increased beyond the permissible limit. Some test specifi-
cations require the determination possible
resonant frequencies, i.
The amplitude, acceleration and, particular, the frequency the vibration must vary during the test. Voltage
drop measured before and after the test to
detect permanent failures, i., determining res-
onance occurs within the frequency spec-
trum passed through.
Beyond these standard procedures, each
market segment performs additional testing. The exact test procedure
may vary considerably, depending how
the product will used.
The test passed if:
• the conductor has neither slipped out the
terminal block nor been damaged
• the maximum permissible voltage drop has
not been exceeded
• and neither contact breaks have occurred
nor defined break time has been exceeded.
Though the requirements such testing
procedures are particularly demanding, test
arrangements are identical for all them.
The test specimen must not damaged in
any way that might affect future use.wago.e.g.
Examples include railway authorities testing
rolling electrical equipment, the testing
performed multiple marine agencies (e. Using vibration table, the test specimen subjected vibration
in each the and axes (see pictures).
• Vibration Test per IEC/EN 60068-2-6; DNV GL, (Marine Applications); 61373 (Railway Applications)
. Analyzing the
specimen behavior under the influence of
resonant frequencies performed using a
special testing procedure.
In common test procedure, for example, wide frequency band continuously run 2000 Hz, different accelerations 20g and
different amplitudes mm.
During vibrations, possible contact breaks
are monitored oscilloscope.
The smaller this value is, the smaller the con-
tact resistance the clamping unit. Test duration minutes per axis.
The vibration test determines whether vibrations, such those produced the vicinity machines vehicles, will permanently affect
the electrical connection, contact breaks will occur during vibrations.e.com
