Procedure
- Based on a design described in ASTM D968 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.
