Dear Harshad V.Paithkar,

The process which is already in use is validated through 3 consecutive batches evidence that the particular requirement for a specific intended use can be consistently fulfilled. If you need more details please ask me.

Thank you sir. I would like to know in more details.

Give me details of your process and stages which is you are interested to validate.

I am developing a semi-quantitative chemical method for determination of some metal ions in aqueous extract.

Dear Harshad V.Paithkar,

Method validation and process validation are different things,generally Method validation terminology used for laboratory used validated analytical procedures and process validation are related to production process consistently produces a result or product meeting its predetermined specifications.you have asked the question How can we define process validation? How to validate an ongoing process?please revised this question now its related to method not with process.

Regards
