scope:

This Standard sets out a method for the sampling of particulate matter in air which impinges on vertical surfaces and procedures for the gravimetric determination of the insoluble solids, ash, combustible matter, soluble solids and total solids content of the collected material.

It should be noted that, despite the equivalence of the units used to report the impinged matter mass flux results of this Standard (g/m2/month) and AS/NZS 3580.10.1 (dust deposit gauge), there is no relationship between the results obtained.

NOTES:

1 The samples obtained by the specified sampling procedure may subsequently be subject to physical or chemical analysis.

2 The method provides an estimate of the mean impinged matter flux over a sampling period, typically one month. Particulate matter impingement rates of 0.1 g/m2/month and above may be determined using a monthly sampling period.
