Flooring surface coefficient of friction

[ajk1]

Does anyone know if there is a minimum coefficient of friction that a flooring surface should have so that it is not too slippery? The floor that I am dealing with is a multipurpsoe room in a place of worship, that is used as a gym, a place of assembly, a dance hall, etc. I think that perhaps the ADA has such a value but I do not have a copy of it.

Does anyone know if there is an architectural forum, similar to this structural forum (where I can ask questions like what is the standard height of theatre seats, etc)?

ajk1....0.5 for general surfaces, 0.6 for accessible routes and 0.8 for ramps.

I usually recommend 0.55 to 0.6 for general surfaces as well.

ADA guidance does not:
302.1 Floor or Ground Surfaces

Both section 4.5.1 of the 1991 Standards and section 302.2 of the 2010 Standards require that floor or ground surfaces along accessible routes and in accessible rooms and spaces be stable, firm, slip-resistant, and comply with either section 4.5 in the case of the 1991 Standards or section 302 in the case of the 2010 Standards.

Commenters recommended that the Department apply an ASTM Standard (with modifications) to assess whether a floor surface is "slip resistant" as required by section 302.1 of the 2010 Standards. The Department declines to accept this recommendation since, currently, there is no generally accepted test method for the slip-resistance of all walking surfaces under all conditions.

Interestingly, supposedly, McDonalds has a slip resistance design standard, which makes sense:

Thanks IRstuff for this.
