4. Evaluation Of Performance
4.1 Functions Monitored During Immunity Tests
In order to verify acceptable performance by the EUT during the applied tests, the following
functions were monitored:
●Performance of EUT according to the manufacturer specifications
4.2 Function Tested After Immunity Tests
The following function tests were conducted to verify correct performance by the EUT before and
after each test:
●Performance of EUT according to the manufacturer specifications
4.3 Performance Criteria
4.3.1 Compliance criteria for EN 55024
●Criteria A
The equipment shall continue to operate as intended without operator intervention. No degradation of
performance or loss of function is allowed below a performance level specified by the manufacturer
when the equipment is used as intended. The performance level may be replaced by a permissible loss
of performance. If the minimum performance level or the permissible performance loss is not specified
by the manufacturer, then either of these may be derived from the product description and
documentation, and by what the user may reasonably expect from the equipment if used as intended.
●Criteria B
After the test, the equipment shall continue to operate as intended without operate intervention. No
degradation of performance or loss of function is allowed, after the application of the phenomena
below a performance level specified by the manufacturer, when the equipment is used as intended. The
performance level may be replaced by a permissible loss of performance.
During the test, degradation of performance is allowed. However, no change of operating state or
stored data is allowed to persist after the test.
If the minimum performance level (or the permissible performance loss) is not specified by the
manufacturer, then either of these may be derived from the product description and documentation, and
by what the user may reasonably expect from the equipment if used as intended.
●Criteria C
Loss of function is allowed, provided the function is self-recoverable, or can be restored by the
operation of the controls by the user in accordance with the manufacturer’s instructions.
Functions, and/or information stored in non-volatile memory, or protected by a battery backup, shall
not be lost.
