OS GSO IEC 60255-21-2:2015 Scope
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.
