This document specifies a method for determining the abrasion resistance of rubber using an advanced Lambourn machine. The abrasion loss due to slip caused by the difference in peripheral speed between a disc-shaped rubber specimen and an abrasive wheel rotating independently about their horizontal axes, parallel and pressed against each other with a specified load. The test result may be reported as volume loss versus test duration or abrasion distance, and/or as an abrasion resistance index compared to a control mixture. Lambourn's advanced machine is capable of independently handling various abrasion conditions, such as sliding speed and load; this method is therefore suitable for evaluating, under very diverse severity conditions, mixtures intended for various elastomer-based products, in particular tires, in a wide range of severity conditions. Annex A presents an example of tread rubber testing.
