The ASTM C241 test method is a standard of the American Society of Testing and Materials (ASTM) that measures the potential resistance to wear caused by foot traffic for stones of all types including granite, limestone, marble, and sandstone. This test is used when assessing the potential durability and suitability of stone products for floors, steps, and other applications where abrasion is caused by foot traffic. Specifiers can use these test results as a way to compare the abrasion resistance of different stone types, as well as stones of the same type.
