Tests and Testing Procedures per IEC/EN Standards (continued)

Beyond the standardized testing mentioned above, each market segment performs additional testing. Examples include a railway
company testing on rolling electrical equipment, or by testing by shipping classification societies such as Germanischen Lloyd,
Lloyd‘s Register of Shipping, Det Norske Veritas. Though the requirements of such test procedures are particularly demanding, the
test arrangements are identical for all of them. During vibrations, possible contact breaks are monitored on an oscilloscope. Volt-
age drop is measured before and after the test to detect permanent failures, i.e., checking if electrical resistance at the clamping
unit has not increased beyond the permissible limit. The smaller this value is, the smaller the contact resistance of the clamping
unit.

The test is passed if:
• the conductor has neither slipped out of the terminal block nor been damaged,
• the maximum permissible voltage drop has not been exceeded
• and neither contact breaks have occurred nor a defined break time has been exceeded.

The test specimen must not be damaged in any way that might affect future use.

Since their inception, CAGE CLAMP and CAGE CLAMP S have been routinely tested for their resistance to shock/vibration in

connection with approval tests.

Note:

These test results are based solely on tests conducted under “laboratory conditions.” Usability of the connectors in actual applica-
tions must be investigated by the user.
