60.The concentration of contaminants measured to verify compliance with the standards prescribed in sections 58 and 59 is expressed on a dry basis, under the reference conditions and corrected to 8% oxygen using the formula
E = Ea x (12.9 / (20.9 -A))
“E” is the corrected concentration;
“Ea” is the concentration on a dry basis without correction;
“A” is the percentage of oxygen on a dry basis in the gases at the sampling site.
