This standard is part of a series specifying the vibration, shock,bump and seismic requirements applicable to electromechanical and static measuring relays and protection equipment with or without output contacts. This standard includes two types of test: - the shock test (on energized and non-energized specimen); - the bump test (on non-energized specimen), and is generally based on IEC 68-2-27 and 68-2-29. The requirements of this standard are applicable only to measuring relays and protection equipment in new condition. The tests specified in this standard are type tests.
