|Calibration is a process that ensures that accuracy
is maintained in the measurements produced
by your equipment.
|Validation is a documented process that provides assurance
that a product, service or system consistently provides results within the acceptable criteria.
|Calibration performance of any equipment is compared
against a reference standard.
|There are no reference standards used in validation.|
|Calibration assures accuracy of measurements.||Validation provides proof of consistency across all the processes, batches of products or methods being used.|
|You must periodically calibrate your instruments.
Identify if there is a ‘drift’ in the measurements and eliminate
it through calibration.
|There are no such requirements for validation. It should be performed when you make any change in the existing system or when the revalidation period has reached.|
|It should be performed as per calibration SOP.||It should be performed as per the validation protocol.|
