Classification of functional status

 

Class A:

All functions of a device/system perform as designed during and after exposure to disturbance.

 

Class B:

All functions of a device/system perform as designed during and after exposure to disturbance. However, one or more of them can go beyond specified tolerance. All functions return automatically to within normal limits after exposure is removed. Memory functions shall remain class A.

 

Class C:

One or more functions of a device/system do not perform as designed during exposure but return automatically to normal operation after exposure is removed.

 

Class D:

One or more functions of a device/system do not perform as designed during exposure and do not return to normal operation until exposure is removed and a device/system is reset by simple “operator/use” action.

 

Class E:

One or more functions of a device/system do not perform as designed during exposure and cannot be returned to operation without repairing the device/system.

Performance criteria for immunity tests

 

Performance criterion A:

The EUT shall continue to operate as intended during and after the test. No degradation of performance is allowed.

 

Performance criterion B:

The EUT shall continue to operate as intended after the test. However, moderate degradation of performance is allowed. No change of actual operating state or loss of memory functions is allowed.
