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 with 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.
Abstract
Overview
ISO 23337:2024 specifies a laboratory method for determining the abrasion resistance of vulcanized or thermoplastic rubber using the Improved Lambourn test machine. The method measures abrasion loss caused by the slip between a rotating disc-shaped rubber test piece and an abrasive wheel. Results are reported as volume loss per abrasion time or running distance, and/or as an abrasion resistance index relative to a reference compound. The standard is suitable for evaluating rubber compounds across a wide range of abrasive conditions (slip rate, sliding speed, load) and includes an example for tyre tread rubber.
Key topics and technical requirements
- Test principle: Independent rotation of test piece and abrasive wheel with their circumferences pressed together; controlled grit feed prevents smearing.
- Apparatus: Improved Lambourn machine with separate drive motors for test piece and abrasive wheel, test chamber, grit-dropping mechanism and loading mechanism.
- Abrasive wheel specifications: Silicon carbide (abrasive C), grit size F80 (ISO 8486‑1), hardness grade K, vitrified bond V, maximum operating speed
