Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the U.S. Department of Defense.1. Scope1.1 This test method covers the determination of

3、the resis-tance to abrasion of vulcanized rubber, or other rubber mate-rials that are similar to the standard reference compound, usedfor the soles and heels of footwear. It is not recommended formaterials less than 2.5 mm (0.1 in.) in thickness.1.2 The values stated in SI units are to be regarded a

Significance and Use3.1 It is recognized that when comparing different types ofrubber materials, the service performance may not correlate tothe results of this predictive test.3.2 This test method should not be used as a measure ofabrasion resistance for compositions t

7、hat differ markedly fromthe standard reference compound. Misleading results, forexample, are obtained from polyurethane compositions whencompared with the standard reference compound.3.3 Some specimens may bounce (chatter) against the abra-sive paper, producing inaccurate results. These should beint

8、erpreted with care and the condition reported.3.4 If test results are inconsistent, the specimens should becut, after the test is run, and inspected for voids. If any voidsare present, the results should be disregarded and the testrepeated using test specimens that are free from voids.4. Test Condit

9、ions4.1 Unless otherwise specified, the standard temperature fortesting shall be 23 6 2C (73.4 6 3.6F), or the standard testtemperature according to Practice D1349.4.2 Humidity affects the abrasive paper; therefore, therelative humidity shall be controlled at 50 6 5 % for at least24 h prior to and d

10、uring testing.4.3 The specimens shall be conditioned at this temperatureand humidity for no less than 24 h prior to testing.5.
