Our Rotary Abrasion Tester is a cost-effective, easy to use and high quality instrument,compared to Taber®* Abraser used to cover a wide spectrum of materials (including plastics, coatings, laminates, leather, paper, ceramics, carpeting, safety glazing, etc.) and is built in conformance to ASTM C501 / C1353 / D4157 / D1044 / D3389 / D3451 / D3730 / D3884 / D4060 / D4685 / D4712 / D5144 / D5146 / D5324/ D6037 / D7255/ F362/ F510/ F1478/ G195/ F1978, TAPPI T476, as well as many other International DIN, MIL, EN, BN, ISO, JIS, SAE, BS, and ANSI standards.

 

For this method of abrasion, a four-inch diameter specimen (flat, round or square shaped), normally less than (½”) or 12.5mm thickness is mounted on a rotating turntable. Abrasive wheels are applied to the sample using a fixed weight. For a specified number of cycles, the abrasive wheels wear away the sample. Usually, two elastomer samples are tested. The result is calculated by measuring the weight loss per thousand cycles of abrasion. Abrasive wheels are commonly made of vitrified clay, and they come in a several levels of coarseness. The test procedure is to abrade specimens against a pair of grinding wheels under a specified pressure. The Rotary Abrasion Tester is supplied with Vacuum unit and optionally a trimming machine may be obtained.

 

With the rotary abrasion method, a rub-wear action (sliding rotation) is applied on the surface of the test piece and the abrasion marks create a pattern of crossed arcs in a circular band that cover an area of 30 cm2. A key characteristic of rotary abrasion tester (abrader / abraser) is the wheels traverse a complete circle on the sample surface, showing abrasion resistance at all angles relative to the grain or weave of thematerial.
