TECHNICAL NOTES
ISOLATION
‘Hi Pot Test’, ‘Flash Tested’, ‘Withstand Voltage’, ‘Proof Voltage’, ‘Dielectric Withstand Voltage’ & ‘Isola-
tion Test Voltage’ are all terms that relate to the same thing, a test voltage, applied for a specified time,
across a component designed to provide electrical isolation, to verify the integrity of that isolation.
All products in this series are 100% production tested at their stated isolation voltage.
A question commonly asked is, “What is the continuous voltage that can be applied across the part in
normal operation?”
For a part holding no specific agency approvals both input and output should normally be maintained
within SELV limits i.e. less than 42.4V peak, or 60VDC. The isolation test voltage represents a measure
of immunity to transient voltages and the part should never be used as an element of a safety isolation
system. The part could be expected to function correctly with several hundred volts offset applied
continuously across the isolation barrier; but then the circuitry on both sides of the barrier must be
regarded as operating at an unsafe voltage and further isolation/insulation systems must form a barrier
between these circuits and any user-accessible circuitry according to safety standard requirements.

REPEATED HIGH-VOLTAGE ISOLATION TESTING
It is well known that repeated high-voltage isolation testing of a barrier
component can actually degrade isolation capability, to a lesser or great-
er degree depending on materials, construction and environment. While
parts can be expected to withstand several times the stated test voltage,
the isolation capability does depend on the insulative materials used.
Such materials are susceptible to chemical degradation when subject
to very high applied voltages. We therefore strongly advise against
repeated high voltage isolation testing, but if it is absolutely required,
that the voltage be reduced by 20% from specified test voltage.
This consideration equally applies to agency recognized parts rated for
better than functional isolation where wire enamel insulation is always
supplemented by a further insulation system of physical spacing or
barriers.
