what is the correct aerosol percentage for dop test ??
Before starting you have to set the concentartion of PAO 100%
and during scanning acceptance criteria ins NMT 0.01%
Acceptance criteria is based upon the efficiency of filter media.
(20-80) Micro gram/litre is a suitable concentration for upstream aerosol challenge then set this conc. as 100% then scan the downstream for leakage with acceptance criteria NMT 0.01 % of upstream conc.(for HEPA filters H14).
