What are different abrasion testing methods?

abrasion testing is a standard procedure used in the production and industry to study the product resistance to damage and wear caused by abrasion. Different methods according to laboratories are used for abrasion testing, but there are several basic methods that are recorded as international standards. These tests are provided by ASTM, indicating that the methods have been developed by ASTM International, an international organization of manufacturing standards. Testing abrasion is used on various products to test abrasion resistance in materials such as color, glue, fabric and metals. To test the pins, a rotating pin is traveled along a solid wear path to form a abrasion on the surface. The dry sand/rubber wheel apparatus uses the spraying rubber wheel, which is located at a set distance from a piece of sample. Dry sand is then inserted into the gap between the wheels of the avzorek flowing in the same direction as the movement of the wheel. The dry sand used has a uniform size and composition of the grain to zAssigning consistent abrasive properties during the test procedure.

One of the examples of PIN testing is the standard test method for abrasion resistance on a coated substance or ASTM D3389, an abrasion testing procedure used to measure abrasive resistance of plastic or rubber substance. This test measures the loss of the weight of the fabric coating or wear that results from the interaction with the rotating pin. Careful weight measurement and material thickness are performed before testing and compares the resulting measurement when the test procedure is complete.

ASTM G132 is another PIN testing method, called a dual PIN method that uses two pins mounted perpendicular to the test product and a control product with a known resistance factor. Protento tests, samples and control materials are considered before testing. Pins move along a continuous path and create wear on the surface of MATerials. When the test is complete, both pieces are removed from the test machine abrasion and re -weighed; The resulting weight loss is measured by a formula that includes warranties against changes in the abrasive properties of pins.

Standard test method for abrasion measurement using a dry sand/rubber wheel, also known as the ASTM G65 test, is an abrasion test that measures the weight or loss of the volume caused by the reins of dry sand. The test is carried out by introducing sand flow into the space between the tested abrasion resistant sample and the tie blade. The test laboratory technician then measures the resulting loss of matter or volume in the sample. This test is commonly used to test abrasive resistance of hard surface coatings such as color, and for testing products, including plastic, metal or ceramics.
