4.19 Isolation Resistance.隔离电阻
4.19.4 Procedure.
Note:For sealed connector pairs,complete all measurements
in this test procedure within one hour after
any previous environmental test.
Note:For unsealed connector pairs,test samples
shall rest at ambient temperature and humidity for
3 h min.prior to measuring isolation resistance after
any previous environmental test.
1 Mate connector pairs.
2 Wrap metal foil around the exterior of the connector
without contacting any terminals or wires.
3 Remove a minimal amount of insulation from the
ends of the wires.
4 Separate wires under test with sufficient distance
as to have no influence on isolation resistance
between any two wire pairs.
5 Measure the isolation resistance by applying
500 VDC between all adjacent pairs of terminals.
6 Record the resistance after 15 s of stabilized readings.
7 Attach all the terminated wire leads to the positive
lead of a Mega-Oh
