BS 903-A9:2020

Abrasion resistance of rubber is an important technological property but no single abrasion test method can simulate the various conditions that rubber products can be subjected to in service. A considerable number of abrasion tests have been developed and many of them are given in BS ISO 23794. BS ISO 23794 also outlines the different wear mechanisms and the significance of the various abradants and test conditions.

This British Standard describes two methods using apparatus commonly referred to as the Akron abrader and Taber abraser. The Akron machine uses wheel on wheel geometry and is notable for the ability to vary the degree of slip by changing the relative angle of the wheels. The Taber abraser uses a pair of wheels in contact with a driven flat disc test piece. Its notable features are that the force on the wheels and the nature of the abradant can easily be varied and the test can be carried out in the presence of liquids.
