Scope:

ASTM D3389 test is used for determining the abrasion resistance of fabrics coated with plastic or rubber in end-use performance conditions. This test has two methods: Method A for abrasion to endpoint and Method B for abrasion for a specified number of cycles with determination of mass loss.

Test Procedure:

In the ASTM D3389 test, firstly the original weight of the test sample is measured, then the sample is mounted on an abrasion tester. A load stated by ASTM D3389 is placed on the top of the abrader wheel and then the wheel is allowed to spin for a stated number of revolutions. Various abrading wheels are run and the final weight is taken. The wheel and load can be regulated for harder and softer materials.

Sample size:

For ASTM D3389, the test samples are cut approximately 100 mm (21.5 inches) in diameter. A hole of 6 mm (0.25 inches) is cut in the center of the sample.

Data:

Results are expressed by changes in weight loss in mg/number of cycles. 

Conclusion:

ASTM D3389 test is used for determining the abrasion resistance of fabrics coated with plastic or rubber in end-use performance conditions
