BS EN 60255-21-1:1996

This standard BS EN 60255-21-1:1996 Electrical relays. Vibration, shock, bump and seismic tests on measuring relays and protection equipment is classified in these ICS categories:

• 29.120.70 Relays

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 68-2-6.

The requirements of this standard are applicable only to measuring relays and protection equipment in a new condition.

The tests specified in this standard are type tests.

Includes the acceptance criteria to be satisfied during and after testing. Also specifies test severity classes for the relays; and covers both vibration response and vibration endurance tests as in Part 2.1Fc of BS 2011.
