WORKING PRINCIPLE

• The Din Abrasion Tester is primarily useful to determine the abrasion resistance of vulcanized rubber. This is against abrasive forces using a cylindrical type rotary drum. It may also be useful to determine the resistance to abrasion of other types of materials. 

• Basically, the Din Abrasion Tester determines abrasion quality of flexible materials. For example, rubber, tires, leather and others. It complies with various international standards.

• A DIN tester is used to ensure that only quality and durable materials are used in manufacturing products that use rubber as a component.

• A DIN abrasion test is accomplished by moving a piece of rubber against an abrasive material or sheet mounted on a spinning drum, also called a rotary drum abrader. The amount of material that will be scraped away in the abrasion process is expressed as volume loss in cubic millimeters or as a resistance index expressed in percent.

• If the test results in a high amount of volume loss, it denotes that the material is low in quality and durability.

TESTING PROCEDURE

To test, abrade the test sample which is cylindrical in shape across a surface. This is with the set abrasiveness for a specific distance under a certain load. The DIN rubber abrasion testing technique requires only a few steps to complete.

• Prepare a sample for the testing, preferably around 16 mm in length. Check for the initial weight of your sample.

• Fit the sample in the tester’s sample holder. Now, switch on the power supply. You will see the sample continuously moving from left to right through a rocker switch that rubs the sample against the revolving drum.

• When the test cycle is complete, remove the sample and weigh it again. The difference between the initial and final figures represents the loss in volume achieved through the test.
