6.4 Changes from previous issues. Marginal notations are not used in this revision to identi-
fy changes with respect to the previous issue due to the extensiveness of the changes.
6.5 Filtration efficiency testers and aerosol materials. The TDA 100 Filter Penetration
Tester manufactured by Air Techniques Inc. has been found to be capable of performing the
filtration efficiency test when operated with Poly --- Alpha Olefin (common trade names are Ethyl
Flow 164 and Emery 3004) or Dioctylphthalate (DOP) as the aerosol agent. DOP is not recom-
mended because of its potential as a carcinogen. Filtration efficiency is calculated by subtracting
the measured percent penetration from 100 percent.
%P = [(PPM downstream)/(PPM upstream)] x 100%
Eff = 100% --- (%P)
Where:
PPM --- Particles Per Minute
%P
--- Percent Penetration
Eff
--- Filtration Efficiency
