Sets out a size-selective sampling procedure and a gravimetric method for the determination of suspended particulate matter in ambient air. The method provides a measure of the PM(sub)10 concentration of particles in ambient air.

This Standard Sets out a gravimetric method for the determination of suspended particulate matter in ambient air. The method provides a measure of mean concentration of PM10 over the sampling period employed. A procedure for assessing the performance of samplers, so that they can comply with the sampling PM10 requirements of this method, is described in Appendix A. NOTES:1. Sampling is normally of 24 h duration to average out diurnal variations. Provided that the mass of the filter is determined under carefully controlled laboratory conditions, mean concentrations of 1 mg/m 3and greater may be determined using a 24 h sampling period.2. It is possible that some particulate matter, depending upon its hygroscopicity, may alter slightly in mass from its initial as-sampled state because of the filter equilibration procedure referred to in Clauses 7.1 and 7.4. Such slight and indeterminable changes, if they occur, are considered insignificant.
