What does “COF” mean?
“COF” stands for “Coefficient of Friction”. COF is a test used to measure the friction or slippage of a tile espanolviagra.net. The measurements are important factors to consider when evaluating a tile’s slip resistance. However, other factors can also affect slip resistance such as a person’s type of shoe, the degree of wear on that shoe and the presence of water or dirt on the tile’s surface.
