BS EN 60255 21 1 is part of a series specifying the vibration, shock, bump and seismic requirements applicable to measuring relays and protection equipment (with or without contacts). BS EN 60255 21 1 includes two types of vibration tests: the vibration response test and the vibration endurance test, and is generally based upon IEC 68 2 6. The requirements of BS EN 60255 21 1 are applicable only to
