Floor Flatness Testing Procedure

This standard allows for numerous techniques for gathering the required date including levels inclinometers profilometers and other means.
Floor flatness testing procedure. The minimum local values mlv are typically applied to each single placement test section and the specified overall values sov are applied to the combined f number values for the entire floor test sur face. 4 1 this test method provides a quantitative method of measuring collecting elevation measurements over a floor system to evaluate the surface s general degree of levelness using the u s. If the rate of testing is not known then we would recommend the following formula to calculate the minimum number of straight edge tests. Ff and fl numbers floor flatness and levelness f numbers provide architects and contractors a method of determining the flatness and levelness of a concrete floor slab.

Floor flatness testing is a common testing procedure for large floor slabs but does come with a high entry equipment cost. 4 2 this standard does not purport to address all of the safety concerns if any associated with its use. They are calculated using the standards set forth in astm e1155 which is the standard test method for determining fffloor flatness and flfloor levelness numbers. If the entire floor is placed in one pour a test section could be the same as a test surface.
1 1 this test method covers a quantitative method of measuring floor surface profiles to obtain estimates of the floor s characteristic ff flatness and fl levelness face floor profile numbers f numbers using the inch pound system of units.

Issues with the testing data we have required the sample measurement lines to be parallel and perpendicular to column lines and not diagonally oriented.
Unlike the more common random traffic f number system of floor flatness and floor levelness ff fl which uses statistical analysis to determine the overall floor condition with a 90 confidence level the f min system is a direct measurement methodology for determining what the vna trucks will experience while operating in the vna aisleway.
