ISO 4649 Rubber, Vulcanized or Thermoplastic - Standard Test for Determination of Abrasion Resistance Using a Rotating Cylindrical Drum Device

ISO 4649 specifies two methods for determining the wear resistance of rubber by means of a rotating cylindrical drum device. The methods involve determining the volume loss due to the abrasive effect of rubbing a test piece against a certain grade of abrasive plate.

Method A is for a non-rotating test piece and method B is for a rotating test piece. The result for each method can be reported as an index of relative volume loss or wear resistance.

These test methods are suitable for comparative testing, quality control, specification conformity testing, arbitration purposes, and research and development work. It cannot be said that there is a close relationship between the results of this wear test and service performance.

Because the entire surface of the test piece is in contact with the abrasive plate during the test period, the wear loss is generally more uniform when using a rotating test piece. However, there is considerable experience with the use of the non-rotating test piece.

All tests are comparative, as factors such as the grade of the abrasive plate, the type of adhesive used in the manufacture of the plate, and the contamination and wear from previous tests lead to changes in the absolute wear loss values. Treatments with a reference compound are included so that results can be expressed as a relative volume loss compared to a calibrated abrasive plate or as an index of wear resistance compared to a reference compound.
