The ASTM D4966 test method is a standard of the American Society of Testing and Materials (ASTM) that measures a textile’s ability to withstand abrasion using the Martindale method. Named after the inventor of the testing machine, this test method is often referred to as the Martindale abrasion test. Abrasion resistance testing is one of several components used when assessing the durability and potential lifespan of a textile for upholstery use.
The scope of testing involves rubbing test specimens against a standard wool fabric abradant in elliptical-shaped rotations or cycles. Procedure requires that the species be checked every 5,000 cycles, assessed for change in appearance or damage, and then rated. The test is concluded when two yarn breaks occur or when noticeable wear occurs.
