Functional Test Versus Performance Verification
Functional tests are tests of various instrument parameters that give a high
degree of confidence that the analyzer is operating correctly. They are
recommended as a check of analyzer operation for incoming inspection or after
a repair. Measurement uncertainty analysis is not available for functional tests,
and the analyzer is checked against limits that are wider than the published
specifications. The functional tests are designed to test an analyzer operating
within the temperature range defined by the analyzer specifications using a
minimum set of test equipment. If a test does not pass, performance
verification tests must be run to determine whether a problem exists.
Functional tests use a minimum set of test equipment to check a much smaller
range of parameters (and a limited number of data points for each parameter)
than do performance verification tests. Functional tests use limits that are
wider than the published specifications; measurement uncertainty analysis is
not available for functional tests.
Performance verification tests span a wide range of instrument parameters and
provide the highest level of confidence that the instrument conforms to
published specifications. These tests can be time consuming and require
extensive test equipment.
If a functional test does not pass, you must run performance verification
tests to determine whether a problem exists.
