DCOF - ANSI A326.3
ANSI A326.3 is the standard for accurately determining the dynamic coefficient of friction (DCOF) on a tile surface. Developed by the Tile Council of North America (TCNA), ANSI A326.3 is a repeatable, reproducible method of measuring DCOF. This method uses a specifically engineered device to perform the required testing, ensuring the most precise results. The ANSI A326.3 is included in the latest version of ANSI A137.1 Specifications for Ceramic Tile.
