Abstract

1 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 IEC 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.
