Full title and description

ISO 4649:2024 — Rubber, vulcanized or thermoplastic — Determination of abrasion resistance using a rotating cylindrical drum device. This International Standard specifies two test methods (Method A: non-rotating test piece; Method B: rotating test piece) for measuring volume loss caused by abrasive action of a specified abrasive sheet on rubber specimens, and provides results as relative volume loss or an abrasion resistance index.

Abstract

The standard defines procedures for determining abrasion resistance of vulcanized or thermoplastic rubber using a rotating cylindrical drum device. It covers specimen preparation, apparatus configuration, test conditions, measurement of volume loss and reporting of results for comparative testing, quality control, specification compliance, referee testing and R&D. The document notes that test results are useful for comparisons and quality control but do not necessarily correlate directly with in-service performance.

Scope

ISO 4649:2024 specifies two laboratory test methods using a rotating cylindrical drum device to determine the abrasion resistance of vulcanized or thermoplastic rubber. The methods measure volume loss caused by rubbing a test piece against a specified grade of abrasive sheet under defined loads and motion. Method A uses a stationary test piece against the moving abrasive; Method B uses a rotating test piece. The scope covers test apparatus, specimen geometry and preparation, conditioning, test procedure, calculation of volume loss or abrasion resistance index, and reporting. The standard is intended for comparative testing, quality control and research, but explicitly states that test results should not be assumed to predict service performance directly.

Key topics and requirements

• Definition of two test methods (Method A: non-rotating specimen; Method B: rotating specimen).
• Specification of the rotating cylindrical drum apparatus and abrasive sheet grade.
• Specimen dimensions, preparation, conditioning and mounting requirements.
• Test parameters: normal load, drum speed, number of cycles/rotations and environmental conditions.
• Measurement procedures to determine volume loss and calculation of abrasion resistance index or relative volume loss.
• Reporting requirements including test method used, specimen identification, test conditions and results.
• Guidance that results are comparative and suitable for QC and R&D; do not directly equate to in-service life without additional correlation work.

Typical use and users

Used by rubber and elastomer producers, component manufacturers (including tyre and conveyor-belt makers), independent test laboratories, R&D teams, and quality-control departments to evaluate and compare abrasion resistance of rubber compounds and finished products. Laboratories use the standard for specification compliance, batch acceptance testing, material development and referee testing.

Related standards

ISO 4649 commonly references other rubber and testing standards for specimen preparation, conditioning and complementary measurements. Examples appearing in national references and adoptions include ISO 48‑4 (rubber — hardness), ISO 2781 (rubber — density), ISO 2230 (storage of rubber), and other normative documents cited in national reproductions of ISO 4649:2024. Users should check the normative references listed in the published ISO text or their national adoption for the definitive list.
