Electrical relays. Vibration, shock, bump and seismic tests on measuring relays and protection equipment - Vibration tests (sinusoidal)1 Scope 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 6826. The requirements of this standard are applicable only to measuring relays and protection equipment in a new
