What is deference between validation and calibration
Please go through the following link.
Thank You so much Sir.
Validation is a general term used for validation or qualification. But in general, validation is used with process. For example process is validated, such as Process Validation, Method Validation, etc. and qualification is used with equipment/system (equipment qualification). For example, Sealer qualification, Refrigerator qualification, Part washer qualification, etc.
Calibration of equipment under qualification is verified under qualification protocol (to verify that the calibration is current). In process validation, it is verified that all equipment used for the process are qualified.
Deference between controlled and uncontrolled area.
