A DCOF reading is not the same thing as slip resistance
The Tile Council FAQ fetched on 2026-10-11 says slip resistance and dynamic coefficient of friction are not synonyms. The standard it quotes defines DCOF as the force needed to keep one surface sliding over another, divided by the weight, or normal force, of the sliding object. Dirt, water, soap, oil, or grease can change that ratio. The FAQ labels itself as discussion of ANSI A326.3, not as legal advice.
What else the FAQ lists
A slip also depends on the shoe sole and how worn it is, the contaminant on the floor, the speed and length of the stride, the person's physical and mental condition, whether the floor is flat or inclined, and how the surface is used and maintained. The flooring's own DCOF, the structure of the surface, and how liquid drains are further items on that list. A single lab ratio does not retire the rest of the list.
This note still has no cutoff
The fetched FAQ text used here does not print a pass-fail number. This page does not invent one, and it does not assign a product-use category to any tile.
