Methods for sampling and analysis of ambient air - Determination of suspended particulate matter - PM(sub)10(/sub) dichotomous sampler - Gravimetric method
Sets out a sampling procedure and a gravimetric method for the determination of suspended particulate matter in ambient air. The method provides a measure of the mean concentration of PM(sub)10(/sub) of two particle size fractions, viz. less than approxi
