Definitions:
------------
Calibration: This is an act of checking or adjusting by
comparing with known standard for accuacy of the instrument
to meet the defined criteria with a specificed degree of
confidence.
Performance Verification:
-------------------------
It is an activity to document that the instrument
consistently performs accordingly to the predefined
specifications which is appropriate for intended use.
Differences:
------------
Calibration is the process where we can do adjustment is a
part of calibration but not necessary.
Where as Peformance Verification is only the act to check
the Performance of the instrument.
Example
-------
Using Salicylic acid and Prednisone Tablets for Dissolution
Apparatus (Chemical testing) is a Performance Verification
test rather being called as "Calibration" since we are
checking the performance of the equipment whereas we are
not doining any adjustment at any point of time .Hence it
is eventually called as "Performance Verification"
