NF ISO 4649, T46-012 (08/2024)

ISO 4649:2017 specifies two methods for determining the resistance of rubber to abrasion using a rotating drum device. The methods consist of determining the volume loss of a rubber specimen subjected to abrasive action by friction on a specified grade of abrasive cloth. Method A uses a fixed specimen and method B uses a rotating specimen. For each method, the result can be expressed as relative volume loss or by an abrasion resistance index. Both test methods are suitable for comparative testing, quality control, specification conformance, adjudication purposes and research and development work. No relationship can be inferred between the results of this abrasion test and in-service performance. NOTE The use of the rotating specimen often leads to a more uniform abrasion loss as the entire surface of the specimen is in contact with the abrasive cloth throughout the duration of the test. However, there is considerable experience gained using the fixed specimen.
