WebThe Floor Flatness Report - American Concrete Institute WebIn practice, FF and FL values generally fall between 12 and 45. The scale is linear, so that relative flatness / levelness of two different floors will be in proportion to the ratio of their F-numbers. For example, an FF 30 / FL 24 …
WebWhat FF means. The FF (floor flatness) measurement reads the “bumps” (highs and lows) in the slab, and higher numbers are better. The more bumps there are, the lower the FF number will be and the more difficult it … WebIn accordance with EN 15620, the flooring leveling requirements are as follows: Aisle length. Leveling with respect to horizontal ref. Up to 492 ft. +/- .59 in. 820 ft. +/- .79 in. For intermediate aisle lengths (between 492 ft and 820 ft), the data can be interpolated linearly.
