The Falling Sand Abrasion Tester is broadly used to measure the abrasion resistance of paint, lacquers and other organic coatings...

Based on a design described in ASTM D 968 and other internationally recognized test standards, the Falling Sand Abrasion Tester consists of an 8" diameter sand reservoir which includes a 60° taper funnel. Standardized abrasive particles placed in the reservoir are released to a guide tube by an abrasive flow gate key. The guide is a 36" straight, smooth-bore tube which contains the abrasive particles as they fall. Specimens are fixed under the guide tube at a 45° angle in a receptacle that includes an opening at the bottom allowing the abrasive particles to be collected in a container. A sturdy base and support system hold the apparatus in a vertical position.
