Rotating Drum Abrasion Tester (Din)

Model HV-EXP2136
Rotating Drum Abrasion Tester (Din) - In applications where an elastomer is subjected to frequent rubbing or abrasive actions as part of its use, it is of prime importance to ensure that the formulation used has a fair degree of resistance to abrasion. One of the methods for determining the abrasion resistance of elastomers is by a Rotating Drum Abrasion Tester. In this test the elastomer under test is abraded against an abrading surface mounted over a rotating drum. The abrading surface has a specified abrading power. The test specimen, which is in form of a button, is held against it under a fixed load. The abrading surface is made to rub against the test specimen by rotating the drum at a fixed speed, the test specimen being meanwhile made to move along the axis of the drum.
