Oberlin, Ohio -- A new technical document covering the testing of dynamic coefficient of friction (DCOF) of natural stone is now available in the Natural Stone Institute’s Natural Stone Resource Library.
Since the withdrawal of the ASTM C1028 test method for Static Coefficient of Friction, the stone industry has been without a standard test protocol for the measurement of friction for walking surfaces, according to the Natural Stone Institute. The Institute has completed an exhaustive study on the use of the ANSI A326.3 Standard Test Method for Measuring Dynamic Coefficient of Friction of Hard Surface Flooring Materials test procedure on natural stones. Over 300 stone specimens (51 stone types in 6 different finishes) were tested to evaluate the appropriateness this test method for natural stone products.
