10.5 Test Results
There is no way for the CIGUI to determine the outcome of this test as a clear definition of a
failure can not be given. The draft standard called out the following possible test results:
“The test results shall be classified on the basis of the operating conditions and functional specifications
of the equipment under test, as in the following, unless different specifications are given by product
committees or product specifications.
a) Normal performance within the specification limits
b) Temporary degradation or loss of function or performance which is self-recoverable.
c) Temporary degradation or loss of function or performance which requires operator intervention or
system reset.
d) Degradation or loss of function which is not recoverable due to damage of equipment (components)
or software, or loss of data.
As a general rule, the test result is positive if the equipment shows its immunity, for the duration of the
application of the test, and at the end of the tests the EUT fulfills the functional requirements established
in the technical specification.”
The user has to make this determination by observing the unit under test. At the end of a test run,
the following dialog box is displayed. Click on the H
elp button to display the pass/fail criteria
shown above.
