New Slip Testing Announced by TCNA

ORLANDO, Fla. – A new standard for coefficient of friction (COF) testing, intended for ceramic tile, may affect stone flooring for public areas.

The Tile Council of North America (TCNA) announced its DCOF AcuTest method here at Coverings 2012 last week, noted the process will soon replace ASTM C1028 as the specified method for COF testing.

A new version of ANSI A137.1 Specifications for Ceramic Tile will soon be published with the new DCOF AcuTest method.  Additionally, for the first time there will be a minimum COF requirement of 0.42 for level interior tile surfaces expected to be walked upon when wet.  

The new A137.1 will also include a two-page informational section (section 6.2.2.1.10), which will help specifiers better understand how to choose the right tile for every application.

While the TCNA announcement pertains to ceramic tile, the new method could also find applicability in measuring COF for stone surfaces for safety and Americans with Disabilities Act (ADA) compliance.
