Four methods where the wear of the rubber under test is compared with that of a standard rubber under the same conditions. Method A is technically equivalent to ISO 4649 and method D is technically similar to ISO 5470.

This Part of BS 903 describes four methods (A to D) for determining the abrasion resistance of rubber by comparing the wear of the rubber under test with that of a standard rubber under the same conditions. Methods A and D are applicable to rubbers of any degree of hardness, whilst methods B and C are restricted to rubbers with a hardness in the range 55 to 95 IRHD.
