{[Ifiber / (area of grid opening X number of grid openings)] X total area of filter} / (volume of air in cm3) {[1 fiber / (0.0125 mm2 x 9)] X 385 mm2} / 4, cm3 = 0.0009 f/cm3
Justification for the default of 0.005 s/cc if we can’t achieve .0009f/cc:
The 0.005 is a mandatory sensitivity value taken from the AHERA method. When the AHERA was developed many years ago, the 0.005 s/cc was the sensitivity needed to ensure that the instrument was capable of detecting asbestos concentration values greater than the 70 s/mm2.
