ASTM D8115-17 (R2021) pdf free download.Standard Test Method for Rubber Property- Abrasion Resistance (Multi-Directional Platform Abrader).
1.1 This test method covers the measurement of abrasion resistance of rubbers (vulcanized thermoset rubbers and thermoplastic elastomers) that are subject to abrasive/frictional wear in actual service. The abrasion resistance is measured by simultaneously moving 4 test pieces across the surface of abrasive sheets in a soft lissajous movement, and is expressed as volume loss in cubic millimeters where a smaller number indicates better abrasion resistance.
1.2 Test results obtained by this test method shall not be assumed to represent the wear behavior of rubber products in actual service.
1.3 Results obtained by this test have shown to be similar to those obtained using Test Method D5963 and ISO 4649.
1.4 The values stated in SI units are to be regarded as the standard. The values in parentheses are for information only.
5. Significance and Use
5.1 Abrasion resistance is a performance factor of paramount importance for many rubber products, such as tires, conveyor bells, power transmission belts, hoses, footwear, and floor covering. A test capable of measuring resistance to abrasion of rubber, including uniformity of wear behavior under abrasive/frictional service conditions is therefore highly desirable.
5.2 This test method may be used to estimate the relative abrasion resistance of different rubbers. Since conditions of abrasive wear in service are complex and vary widely, no direct corrclation between this accelerated test and actual performance can he assumed.
5.3 This test method is suitable for comparative testing, quality control, specification compliance testing, referee purposes, and research and development work.
6. Limitations
6.1 Test pieces containing voids or porosity. or both, will yield unreliable test results.
6.2 Test pieces that bounce (chatter) over the surface of the abrasive sheet rather than running smoothly will produce inaccurate test results and are not candidates for this test method.
6.3 Test pieces that tend to extensively smear the surface of the abrasive sheet will provide meaningless test results.
6.4 Test results obtained under any of the above conditions shall not be used to reach conclusions regarding the relative abrasion resistance of rubbers.ASTM D8115 pdf download.
