NBS Abrasion Tester
www.WorldofTest.com/nbsabrader.htm
Freezing Testers
www.WorldofTest.com/freezingtester.htm
The NBS abrasion tester is used commonly in the footwear
industry, often to compare materials versus rubber. In the
test, three elastomer samples are abraded across the
surface of a rotating, abrasive drum until 1/10” of the sample
is abraded. A rubber standard is tested before and after the
test. An NBS index is then calculated based on the cycles
to abrade the sample and the rubber standard. The results
are indexed to the rubber standard, which is generally of
low to medium abrasion resistance. For example, if the
tested sample took twice the number of cycles to abrade
1/10”, the NBS abrasion resistance would be reported as
200. In this test, higher numbers indicate higher resistance
to abrasion. Our NBS Abrasion Tester meets ASTM D-1630

NBS Abrasion Tester
www.WorldofTest.com/nbsabrader.htm
Freezing Testers
www.WorldofTest.com/freezingtester.htm
The NBS abrasion tester is used commonly in the footwear
industry, often to compare materials versus rubber. In the
test, three elastomer samples are abraded across the
surface of a rotating, abrasive drum until 1/10” of the sample
is abraded. A rubber standard is tested before and after the
test. An NBS index is then calculated based on the cycles
to abrade the sample and the rubber standard. The results
are indexed to the rubber standard, which is generally of
low to medium abrasion resistance. For example, if the
tested sample took twice the number of cycles to abrade
1/10”, the NBS abrasion resistance would be reported as
200. In this test, higher numbers indicate higher resistance
to abrasion. Our NBS Abrasion Tester meets ASTM D-1630
