This standard is part of a series specifying the vibration, shock, bump and seismic requirements applicable to measuring relays and protection equipment (with or without contacts).
This standard includes two types of vibration tests: the vibration response test and the vibration endurance test, and is generally based upon IEC 68-2-6.
The requirements of this standard are applicable only to measuring relays and protection equipment in a new condition.
The tests specified in this standard are type tests.
