ASTM D5252 Operation of the Hexapod Tumble Drum Tester
The ASTM D5252 test method is a standard of the American Society of Testing and Materials (ASTM) that measures a carpet’s surface appearance retention using the hexapod tumble drum. This test is one of several components used when assessing the potential performance of pile yarn floorcoverings. The scope of testing involves securing a carpet specimen along the inside diameter of a rotating drum apparatus. As the drum rotates, a metal ball covered with polyurethane studs tumbles around inside the drum to simulate traffic or wear. The specimen is then checked and rated based the change of appearance and color in the surface.
