Until recently, dust fall-out monitoring equipment, which adhered to the strict ASTM D1739–98
regulations, were difficult or nearly impossible to come by in South Africa.
Dustco wanted to make a difference...
Introducing Dustco’s ASTM Dust Monitors
Dust Monitoring Stands
Our dust fall-out stands are manufactured in South Africa from stainless steel. They are strong and durable and 100% compliant with the ASTM D1739-98 specifications.
Dust Monitoring Buckets
Our dust monitoring weatherproof buckets are also made locally and come standard with tight-fitting plastic lids. Our buckets and lids are made according to the exact size and dimensions of the ASTM standard.
How to follow the ASTM D1739–98 dust fall-out method
- Place an ASTM-compliant open-topped cylinder (or bucket) on a stand for a period of about 30 days to catch any dust fall-out.
- The top of the bucket must be at a height of 2 metres above ground level and the stand must be fitted with a windshield.
- The bucket must be at least 150 millimetres in diameter with a height no less than twice its diameter and made of either stainless steel or weather-proof plastic. .
- A tight-fitting lid is needed for each container for transport to and from the monitoring site..
-
In the laboratory, the gravimetric determination of the dust collected in the bucket is done and reported as grams per square metre per 30 days
(g/m2 /day)

Why fall-out dust monitoring needs to follow ASTM standards?
Dust is a generic term used to describe fine particles that are suspended in the atmosphere, which can be a major cause of nuisance, health and environmental effects. The measurement of the vertical flux of dust, also called dust deposition or dust fall-out, is one of many methods employed to monitor dust in an area. There are a number of standard vertical-gauge systems developed to measure dust deposition gravimetrically. South African legislation prescribes the use of the “Standard Test Method for Collection and Measurement of Dust-fall” as published by the ASTM (ASTM D1739 – 98 (Re-approved 2017)).
The specifications with regards to the buckets made them commercially unavailable in the South African market. As a result, many industry players used other bucket shapes and sizes as a compromise. Inevitably, these are all near-misses and recent legislative and auditing requirements have made it necessary for industries and mines to align more stringently with the ASTM specifications for both stands and buckets.
