@aparnajagadale Qualification of every instrument and equipment is not written in guidelines but a common statement is written everywhere that every equipment and instrument should be qualified. therefore your passbox should be qualified after installation performing the test for viable and non-viable particle count.

Dear sir,

Can you please help ,if you have any idea about guideline for passbox qualification.


Dear Aparna

You must perform 2 test for the qualification of your passbox

Active-passive air microbial count
Surface microbial contamination
Viable and non-viable particle count

You must perform these tests for 3 days, and the maximum limits are depends on your passbox class ( A-B-C-D class)

I’m in a holiday now so i dont have access to all of my files, but i think the referance guide is Gmp or iso

Thank you sir
