ASTM D4157 Abrasion Resistance of Textile Fabrics (Oscillatory Cylinder Method)
The ASTM D4157 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 oscillatory cylinder method. Named after the inventor of the testing machine, this test method is often referred to as the Wyzenbeek 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 cutting test specimens from both the warp and weft directions and pulling them tight in a frame. While the specimens are being held stationary, an ACT approved #10 cotton duck fabric is rubbed back and forth as an abradant against the specimens. For olefins and low-melting fibers, a wire screen abradant is recommended.
Each back and forth movement is considered one double rub, which serves as the unit of measurement used for reporting the test results. Procedure requires that the specimens be checked every 5,000 double rubs and assessed for damage. The test is concluded in one of three ways: when two yarn breaks occur, when noticeable wear occurs, or when 100,000 double rubs are reached. Specimens can be tested to receive a higher result if no damage is detected at the 100,000 double rubs interval.
