Press Release Summary:
Model 6160 measures relative resistance or susceptibility of material to surface abrasion and scratching caused by oscillating abrasive media. Specimens are mounted in holder located in bottom of tray, which is filled to uniform depth with standardized abrasive media. With optional Bayer Test Kit, unit can determine abrasion resistance of ophthalmic lenses. Speed range is 100-200 cycles/min, and adjustable stroke range is 0.25-6.0 in.
Original Press Release:
Oscillating Abrasion Tester Model 6160
The Model 6160 (replaces Model 6100) is based on the "oscillating sand tester". The instrument is used to measure the relative resistance or susceptibility of a material to surface abrasion and scratching caused by an oscillating abrasive media. The specimens are mounted in a holder located in the bottom of a tray which is filled to a uniform depth with a standardized abrasive media. The tray reciprocates in a back and forth motion which causes the entire mass of the abrasive media to shift. With the optional Bayer Test Kit, the Model 6160 can determine the abrasion resistance of ophthalmic lenses. Applications of the Bayer Test include transparent materials and coatings.
The new design of the Oscillating Abrasion Tester allows for increased operating stability. The speed range has remained 100-200 cycles per minute but the range of stroke lengths have increased - there is now an adjustable range from 0.25 - 6.0 inches (6.5 - 152.5mm).
The Model 6160 includes: specimen tray with square specimen holder; 4/10 silica abrasive media (50 lb); spirit bubble level; specimen spacers (set of 8); disposable tray cover; specimen removal tool; 6 inch rule; power cords; mounting hardware; and operating instructions.
