ASTM D1044 (Haze), ASTM D4060 (Weight Loss) Taber Abrasion

Scope:

Taber abrasion determined by ASTM D1044, ASTM D4060 testing method evaluates plastic’s resistance to abrasion. This is done by measuring optical effects and resistance of organic coatings produced by the Taber Abraser on coatings done on a plane, rigid surface, such as a metal panel. Abrasion resistance is defined as a material’s ability to resist mechanical effects such as rubbing, erosion or scraping. Abrasion can be hard to compare, but a haze or weight loss is easily assessed.

Test Procedure:

The haze or initial weight is measured for the test sample. The test sample as specified by ASTM D1044, ASTM D4060 is then put on the abrasion testing device. On top of the abrader wheel a load of 250, 500, or 1000 grams is placed and allowed to rotate for the specified number of revolutions. Different wheels are shown for abrading. A haze or final weight assessment is carried out. For softer and tougher materials the load and the wheel may be regulated.

Specimen size:

4-inch diameter disk or 4 sq. inch plate

A ¼ inch diameter hole in the center is necessary.

Data:

Results are given by variations in % haze or weight loss in mg per number of cycles. 

Conclusion:

ASTM D1044 is a standard test method for resistance of transparent plastics to surface abrasion while ASTM D4060 test determines abrasion resistance of organic coatings by the taber abraser.
