My company has Old Japanese Coating machine.
and I’m gonna do the PQ for tabelt coating machine.
The instruments that the machine has, are analog temp. indicator(Supply and exhaust), RPM meter, mist checker(for air flow), flow meter(for coating liquid).
Supply temp. can be controlled ,but the Exhaust temp. is not controled(just for monitoring.)
Which items are subject to the PQ?
DO I have to check Temp, RPM, airflow rate, like OQ?
Or Do I have to focus on the product’s physical state? Thickness something like that?
If it does, which one is that?
Please, Tell me what you know.
