Specifies the vibration, shock, bump and seismic requirements that apply to electromechanical and static measuring relays and protection equipment, with or without output contacts. Includes two alternative types of seismic tests: the single axis sine sweep seismic test (method A); the biaxial multi-frequency random seismic test (method B). Includes detailed definitions, selection of test severity classes, criteria for acceptance, tables and diagrams.
