4. Requirements for immunity to disturbances (immunity)
Evaluation criteria according to EN 61000-6-2
Criteria A:
The operating equipment must continue to work as intended during the test. There should be
no interference in the operating behavior and no system failures below a minimum operating
quality as defined by the manufacturer.
Criteria B:
The operating equipment must continue to work as directed after
the test. There should be no
interference in the operating behavior and no system failures below a minimum operating quality
as defined by the manufacturer.
Criteria C:
A temporary function failure is permitted if the function restores itself, or the function can be
restored by activating configuration and control elements.
Criteria D:
Impairment or failure of the function, which can no longer be established (operating equipment
destroyed).
