4. Allow the termination to air-dry in the
This method, when tested on various
surfaces including silicone rubber and
glazed porcelain, has repeatedly produced a
coating thickness of from 0.12 to 01.15
grams per square inch of surface.
The terminations are then tested in a
contamination building. All terminations are
mounted vertically. The uniform fog rate
called out in ASTM-D-2132 is obtained by
the use of special atomizing, wide-angle
nozzles.
An on/off cycle is controlled to give a fog
rate of 7 to 9 milligrams per square inch per
minute.
Each sample is energized at 8.7 kV. The
system is set up such that approximately
500 milliamps trip the circuit breaker. All
