Praveen,
In this area the use of terminology is interchangeable and confusing.
Calibration implies testing (and adjustment if required) and would usually be performed according to the manufacturer's trained service providers working to specifications set out by the manufacturer (there may differ between manufacturers.
However, you could be referring to "qualification" (annual performance testing or daily system suitability testing) performed by the end user to ensure that the instrument performs to the same standard consitently.
Given the massive amount of differing applications HPLC and now UPLC is used for as well as the huge range of manufactruers, there is not a single unifying set of criteria.
