One hard floor can carry more than one A326.3 use class
To meet ANSI A326.3, a hard-surface flooring product shall be classified into one or more of the provided classes, meaning whatever classes apply. The Tile Council questions page states that directly and then gives a single example.
The example on the page
A product classed as Interior Wet Plus would likely also be classed Interior Dry and Interior Wet. That is how one hard floor carries more than one use class: the wetter class stays alongside the drier classes that apply. The page does not say a Wet Plus mark replaces the drier classes.
No extra cap is stated
The question on the page asks whether there is a limit on how many classes one product can carry. The answer is the applicable classes, not a maximum count. The classes are a set, not one exclusive slot, and the page does not tell a maker to stop at a fixed number.
