APPENDIX A - Selection criteria for shock and bump test
parameters a) and output circuit response
during shock response test b)
This standard includes two types of tests; - the shock test (on energized and non-energized specimen). - the bump test (on non-energized specimen). These requirements are applicable only to measuring relays and protection equipment in a new condition.
