This International Standard 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 circumfrerntial speed between a discshaped 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, under a wide range of severity conditions, of compounds for a range of rubber products,especially tyres. An example of the testing of tyre tread rubber is given in Annes A.
