TEST: ASTM D4060
Taber Abrasion is a test using a weighted abrasive wheel that rotates at a constant speed to determine
the resistance of finishes to abrasion and wear, as stated by test standard ASTM D4060.
7 competitive finishes including Cerakote™ H-146 Graphite Black were tested in accordance
with ASTM D4060. Each finish was tested three separate times in order to validate the test
result. Panel weights and mil thickness were measured prior to the start of each test to determine
a wear rating. A 1000 gram weight was placed on a CS-17 Taber Abrasion wheels as required
by ASTM testing standards for testing finishes. Panels were cycled until the Taber wheel
wore through the finish to the steel substrate. Finishes that required more than 500 cycles to
wear through to the substrate were stopped every 500 cycles for the Taber abrasion wheels to
be cleaned. Cleaning the Taber wheels every 500 cycles is a requirement to ensure accurate results.
Once the Taber wheel has breached the finish, the Taber abrader is stopped and a final
weight is taken to determine the wear rating for each finish. Wear ratings are calculated by taking
the weight of the test panel before abrasion and subtracting the weight of the test panel after
abrasion and multiplying that by 1,000. That number is then divided by the number of cycles
completed before the finish was worn through. The resulting number is the specified wear rating
for that finish. Based on ASTM testing standard D4060, Cerakote™ Finished Strong by lasting
nearly twice as long as the nearest competitive finish and 24 times as long as the furthest competitive
