Number of Relays: 5
Number of samples: 5
Measurement conditions: Increase and decrease the specified shock
gradually imposed in ±X, ±Y, and ±Z directions three times each with
the Relay energized and not energized to check the shock values
that cause the Relay to malfunction.
Criteria: There must not be any contact separation for 1 ms or greater
with a shock of 100 m/s
a shock of 20 m/s
