S concentration:
5 ±3 ppm. The change in contact resistance was measured after
leaving the Relay in the above environment for a fixed amount
of time, then removing it to a constant-temperature and
constant-humidity environment for at least 30 minutes.

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