ASTM D4060

Micom offers Taber Abraser testing to ASTM D4060 – Abrasion Resistance of Organic Coatings by the Taber Abraser – test services as part of its Surface Coatings testing offering. These test methods were introduced in around 1930 to perform accelerated wear testing. Its simplicity and effectiveness made the device adopted almost instantaneously for a multitude of test protocols/specifications on a wide variety of products around the world.

Testing to ASTM D4060 involves mounting a flat specimen to a turntable that rotates horizontally at a fixed speed.  Two arms, each supporting an abrading wheel, are then lowered so that each wheel touches the surface.  Before starting the test, a “suction arm” is lowered between the wheels to remove the abraded material from the sample’s surface. The turntable then starts rotating forcing rub-wear action of the wheels against the sample’s surface for the specified number of cycles or until a given mass of coating has been lost or until the wheels start exposing the substrate.

Abrasion Resistance – Use and factors to be considered:

ASTM D4060 is used for measuring the wear resistance of organic coatings applied flat, rigid test samples.  ASTM D1044 is used for transparent plastic materials to evaluate their capacity to maintain their optical properties, upon typical, wear to be expected while in service.

Abrasion resistance to ASTM D4060 is usually measured as a weight or a coating thickness loss after a given number of cycles.  Each arm, by default, is loaded to apply a 250 g. pressure on each wheel.  Depending of the product/specification used, this weight can be increased to 500 or 1000 g.  The abrading wheels are available in different grit for a more or less abrasive action.

Typical Experimental parameters:

Number of specimens/product: 2 specimens
Specimen dimensions: 4” X 4” with a maximum thickness of 6-7 mm
Conditioning and testing Temperature: 23 ± 2 °C
Conditioning and testing relative humidity: 50 ± 5%
