Oscillating abrasion tester 6160

Brand: TABER

Description: The TABER® Oscillating Abrasion Tester - Model 6160 is best known as an "oscillating sand tester". Described in ASTM F735 (Standard Test Method for Abrasion Resistance of Transparent Plastics and Coatings Using the Oscillating Sand Method), the oscillating sand tester is used to measure the relative abrasion resistance of a material to surface abrasion and / or marring.  The primary application of the Oscillating Sand Abrasion Tester is for transparent materials and coatings utilized in windows and lenses, but it might also be used to evaluate organic paints & coatings, plastics, metals and other materials.

Abradants

• Reference abradant in ASTM F735 in a quartz silica sand, graded 6/9. Besides the silica abrasive media, other potential abradants include alumina (zirconia), silicon carbide, aluminum oxide and glass bead.  For repeatable test results, the sizing and shape of the abradant is absolutely critical.
• During testing, the abradant may become 'worn' as the sharp edges contact the specimen and other abrasive particles. To ensure reproducibility, new abrasive media should be used for each test.  It is also recommended that the abrasive be replaced after 300 cycles for longer cycle tests.

Evaluation

• Using a haze meter, the haze and light transmission of a transparent test specimen is measured and recorded.  After subjecting the specimen to the specified number of abrasion cycles, the results are measured as a change in haze and light transmission.  Abrasion resistance for opaque materials is measured visually or by weight loss.
