Certificate Of Compliance

Compliance Criteria
The EUT is considered immune to the threat environment if the compliance criteria provided below are
met. These compliance criteria are taken from EN 55024 Section 7.0
For all the immunity tests, the results are evaluated against performance criteria relating to the
operating conditions and functional specifications of the EUT, and defined as follows:
– Performance Criterion A:
The EUT 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 replaces 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.
– Performance Criterion B:
After the test, the EUT shall continue to operate as intended without operator 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.
– Performance Criterion 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.
