Measurement: The rate of deterioration in latching ability was measured
over time with the Relay left at a normal temperature
(20 to 30°C) after latching by applying the rated voltage.

Measurement: Shock was applied in 6
directions along 3 axes 2 times
with the Relay energized and
3 times with the Relay not
energized to check the shock
values that cause the Relay to
malfunction.
