Standard Test Method for Determining <emph type="ital">F<inf>F</inf></emph> Floor Flatness and <emph type="ital">F<inf>L</inf></emph> Floor Levelness Numbers
SIGNIFICANCE AND USE
5.1 This test method provides statistical (and graphical) information concerning floor surface profiles.
5.2 Results of this test method are used primarily to:
5.2.1 Establish compliance of randomly trafficked floor surfaces with specified FF Flatness and FL Levelness tolerances,
5.2.2 Evaluate the effect of different construction methods on resulting floor surface flatness and levelness, and
5.2.3 Investigate the curling and deflection of floor surfaces.
5.3 Results of this test method shall not be used to enforce contract flatness and levelness tolerances on those floor installations primarily intended to support the operation of fixed-path vehicle systems (for example, narrow aisle warehouse floors).
Note 2: When the traffic patterns across a floor are random, (as is generally the case) evaluation of the floor's FF Flatness and FL Levelness will necessarily involve a random sampling of the surface, since all of the infinite potential profiles to be seen by the traffic can not possibly be measured. In those instances when the traffic across a floor will be confined to specific paths, however, the requirement for random sampling is eliminated, since the floor can indeed be inspected exactly as it will be seen by all of the traffic. In these special cases, rather than inferring the condition of the traffic paths from a random sample, it is far more useful to measure each of the traffic paths directly using continuous recording floor profilometer configured to run exactly in the traffic wheel paths. Such direct simulation measurements eliminate the inherent uncertainties of statistical sampling and provide profile information immediately applicable to the correction of the surface in way of the future traffic.
SCOPE
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.
Note 1: A complete metric companion to Test Method E1155 has been developed, Test Method E1155M; therefore, no metric equivalents are shown in this test method.
1.2 The text of this test method references notes and footnotes that provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of this test method.
1.3 The values stated in inch-pound units are to be regarded as standard. No other units of measurement are included in this standard.
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

3. Terminology
3.1 Definitions of Terms Specific to This Standard:
3.1.1 elevation—height, altitude, vertical location in space. Elevation measurements are always made parallel to the direction
of gravity.
3.1.2 flat—even, plane, homoloidal, free of undulation.
3.1.2.1 Discussion—
For the purposes of this test method, flatness will be measured by calculating curvature value, q, between all 12-in. reading points
separated by 24 in. The curvature value is the difference between successive elevation differences. The mean and standard
deviation of all the curvature values for a given test section are then converted according to the equations in this test method to
get the dimensionless F Flatness Number.
