With the above attachments which explined by sir and also Go through the ISO14644-1,&14644-3 for frequency of the procedure and for limitations,and frequency for PQ and Rq.
What to perform in HVAC Validation?
Than Answer is your User Requirement Specification, which includes requirement.
For the requirement you can refer WHO guideline : http://www.who.int/medicines/areas/quality_safety/quality_assurance/HVAC_Part2_QAS18-759-15022018.pdf?ua=1
above is under draft, but still you can find the requirement.
Test Methodology, Report and criteria , you can refer ISO 14644
Ideally Protocol should cover below requirement (But not limited to) :
- Objective
- Scope
- Responsibility
- Training Participation
- Instrument detail to be used for the Validation activity and their status
- SOP detail
- Acceptance criteria of the test
- Methodology/Procedure of the Test
- Reporting Result
- Non Compliance observed (if any)
- Summary and Conclusion
- Approval of the protocol
Some industries follow Pre Approval and Post Approval concept. but it may vary
Hi. I wonder whether we should operate all equipment 24/7 during phase-2 or not?
Thank you.
Sir what is the main difference between AHu and HVAC?
