The rating agency the tile council of north america states that according to the ansi a137 1 2012 standard ceramic tiles selected for level interior spaces expected to be walked upon when wet must have a minimum wet dcof acutest value of 0 42 numbers can be deceptive as some tile manufacturers still publish older ratings. Tile council of north america tcna promulgates and publishes the standards for tile setting issued by the american national standards institute ansi. Fha hud carpet standards um 44 serve as quality control guidelines and performance criteria requirements for new carpet production.

Australian standards for slip resistance australian standards as for slip resistance previously required a minimum coefficient of friction wet of not less than 0 4 the current standard is now categorised into 5 classes. Hud carpet standards hud um 44 and cushion standards hud um72 set minimum requirements and test methods for carpet products to be acceptable under fha hud programs. How pei ratings are determined.
