Sets out a method for the sampling of particulate matter which is deposited from the atmosphere and procedures for determining mass deposition rates for insoluble solids, soluble solids, ash, combustible matter and total solids.

This Standard sets out a method for the sampling of particulate matter which is deposited from the atmosphere and procedures for the gravimetric determination of the mass deposition rate of insoluble solids, ash, combustible matter, soluble solids and total solids from ambient air.NOTES:1 The sample obtained by the sampling procedure specified may be used for chemical tests or microscopic analysis.2 The method provides a means for measuring the mean concentration of particulate matter in air over a sampling period, normally one month. Concentrations of 0.1 g/m2.month and above may be determined using a monthly sampling period.
