What is DCOF? Stricter, More Accurate Testing Results In Superior Tile Products In 2012 the Tile Council of North America (TCNA) adopted the ANSI A137.1 test protocol known as the DCOF AcuTest for assessing ceramic tile slip resistance for interior application. Shaw Tile & Stone has embraced the TCNA’s new standards for measuring a tile’s frictional resistance as it is closely related to traction and slipperiness. The DCOF AcuTest does not measure the flooring itself but, how the tester, lubricant (sodium lauryl sulfate solution) and tile surface interact which more accurately simulates the conditions of people walking on tile and provides a useful comparison of tile surfaces. The threshold requirement (based on extensive research in Europe and by TCNA) in the American National Standards Institute’s TILE & STONE (ANSI) A137.1 is 0.42 DCOF as measured by the more reliable (in terms of, safety) DCOF AcuTest. This means that tiles suitable for level interior spaces expected to be walked upon when wet should have a DCOF (Dynamic Coefficient of Friction) value of 0.42 or greater replacing the previous 0.60 SCOF (Static Coefficient of Friction) rating over a wet tile surface per the ASTM C 1028 test method. It is Shaw’s commitment to our customers to provide accurate information for our tile products that ensure this new COF criteria in the ANSI A137.1 standard is met and maintained such that Shaw, Shaw Customers and End Users collectively, do our part to minimize any potential for slips and falls in residential and commercial interiors.
