This document specifies a method for the determination of the resistance of rubber to abrasion using
the Improved Lambourn test machine.
The abrasion loss resulting from the slip caused by the difference in circumferential speed between a
disc-shaped rubber test piece and an abrasive wheel, which are driven to rotate independently with
their circumferences pressed against each other by a specified load, is determined. The test result
can be reported as a volume loss per abrasion test time or running distance, and/or as an abrasion
resistance index compared to a reference compound.
As the Improved Lambourn test machine is capable of setting various abrasive conditions, such as slip
rate, sliding speed and load, independently, this method is suitable for the evaluation of compounds for
a range of rubber products, especially tyres, under a wide range of severity conditions. An example of
the testing of tyre tread rubber is given in Annex A.
