I was wondering if you could clear something up for me please.
As part of our qualification of the facility, we measure particle counts, room recoveries, air supply velocity and volume, noise and light levels and pressure differentials between rooms (its an ISO class 5 environment).
Our building management system continuously monitors the pressure differentials and alarms if it goes out of spec.
My question therefore is, are we wasting time and effort measuring the room pressure differentials manuallly with a micromanometer as part of the bienniel requalification, when the BMS monitors it all year anyway?
Many thanks for your help guys,
