The five A326.3 use classes do not cover ramps
The Tile Council questions page asks whether any of the five ANSI A326.3 product-use classes address inclined surfaces or ramps. The answer on that page is no.
A level class is not a ramp class
The classes describe product use for the conditions in the standard. An incline changes the walking problem, and the page does not fold that incline into Interior Dry, Interior Wet, Interior Wet Plus, Exterior Wet, or Oils/Greases. A product can carry one of those five classes on a level floor and still have no ramp class, because none of the five addresses ramps or other inclined surfaces.
What to do with the gap
The page does not supply a substitute number for a ramp. It only marks the limit: those five classes are not a ramp specification.
