Tests and Testing Procedures per IEC/EN Standards (continued)
Other test types are performed using single

Examples include railway authorities testing
rolling electrical equipment, the testing

• Vibration Test per IEC/EN 60068-2-6; DNV GL, (Marine Applications); 61373 (Railway Applications)
.
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.g.
During vibrations, possible contact breaks
are monitored oscilloscope. Some test specifi-
cations require the determination possible
resonant frequencies, i.
The smaller this value is, the smaller the con-
tact resistance the clamping unit.8

may vary considerably, depending how
the product will used., determining res-
onance occurs within the frequency spec-
trum passed through.
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.
Though the requirements such testing
procedures are particularly demanding, test
arrangements are identical for all them. Using vibration table, the test specimen subjected vibration
in each the and axes (see pictures).
In common test procedure, for example, wide frequency band continuously run 2000 Hz, different accelerations 20g and
different amplitudes mm.e.
Beyond these standard procedures, each
market segment performs additional testing.
The amplitude, acceleration and, particular, the frequency the vibration must vary during the test.,
