Remark:
Criterion A (for continuity):
  1. DC output range shall be accordant to normal work situation during interference;
DC output voltage fluctuation shall be within ±10%.
b) There shall not be alarms, failure indication ( power failure or protection failure) or failure indicatioin
after interference.
Criterion B (for transience):   
1. DC output voltage shall not exceed the values belowed:
1) For -48V DC: -60V;
2) For-60V DC: -75V;
2. Spikes during interference shall not be considered.
3. There shall not be alarms, failure indication ( power failure or protection failure) or failure indicatioin
after interference.
4. Recover to normal function after interference.
Criterion C (for interruption):
The temporary lose of function is allowed, the function shall be recoverable automatically or manually, as well as by operation.
Criterion R (for susceptibility)
There shall not be damage or other interruption during test, such as software damage or improper operation of protecting units. The unit shall operate appropriately within specified range( not necessarily during process of test) after  transient electromagnetic phenomenon finished. The interference may result in actions of fuse or other device defined, and shall be replaced or reset before recovering to normal operation state.
