BGD 529 Falling Sand Abrasion Tester is designed according to ASTM D 968. It’s applicable to determine abrasion resistance performance of organic coating. Abrasive is allowed to fall from a specified height through a guide tube onto a coated panel until the substrate becomes visible. The amount of abrasive per unit film thickness is reported as the abrasion resistance of the coating on the panel.
Funnel with fan-shaped switch is more convenient to operate
The distance between guide tube and specimen holder is calibrated by special tool which comes which tester, more precise.
Funnel installation height can be adjusted freely by below bearing.
