Abrasion Tester-Rubber Hardness Abrasion Testing

Abrasion Testing is the process of measuring the amount of material that is worn away from a test item when it is rubbed against a certain grade of abrasive paper. In order to assess the ability of rubber materials, such as tires, conveyor belts, automobile belts, hoses, footwear, and several other goods, to withstand abrasion, it is necessary to subject them to testing in abrasive environments. The Abrasion Tester is an auxiliary testing equipment used to determine the hardness of elastomers against abrasion. It is used since the real performance of rubber goods over their performance cycle is unpredictable.

Basic Equipment

A sample holder (rotating) with different loading weights, a rotating cylindrical roller, an emery sheet placed on the roller and an electrical control.
Optional: An automatic vacuum cleaner connection and an optional heating module.

Standards

DIN ISO 4649, NF ISO 4649, ASTM D 5963
ISO 4649 specifies two methods for the determination of the resistance of rubber to abrasion by means of a rotating cylindrical drum device.
Method A is for a non-rotating test piece and method B is for a rotating test piece. For each method, the result can be reported as a relative volume loss or an abrasion resistance index.

Range Of Application

An abrasion tester is used for the determination of the resistance of an elastomer to friction loss with a rotating or stationary test piece. The applications range from products such as tires, conveyor belts, hoses, footwear, floor covering, etc.
