Changes to coefficient of friction (COF) standards for ceramic tile
Many manufacturers have stopped reporting coefficient of friction (COF) per the C1028 method. Why? The standard for COF for ceramic tile floors has changed! And there is now a ≥0.42 requirement, measured per the DCOF AcuTest®, for level interior tiles that will be walked on when wet.
To meet the new DCOF AcuTest criteria, you cannot use old COF values from C1028 measurements. As the methodology is different, there is no direct correlation from C1028 values to DCOF AcuTest values.
Whether you're manufacturing, specifying, selling, installing, or maintaining ceramic tile floors, it's important to know the DCOF AcuTest value. Need help? The TCNA lab not only runs this test, they have helped develop the protocol. Send in your tiles, and be sure you're meeting this new and very important safety standard.
