ASTM E1155-20

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.

Numbers
This standard is issued under the fixed designation E1155; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (´) indicates an editorial change since the last revision or reapproval.
This standard has been approved for use by agencies of the U.S. Department of Defense.
1. Scope
1.1 This test method covers a quantitative method of measuring floor surface profiles to obtain estimates of the floor’s
characteristic F Flatness and F Levelness Face Floor Profile Numbers (F-Numbers) using the inch-pound system of units.
F L
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 safety, health, and healthenvironmental practices and determine the
applicability of regulatory limitations prior to use.
1.5 This international standard was developed in accordance with internationally recognized principles on standardization
established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued
by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

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. 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.

3.1.5 inclinometer—a Type II device (see 6.1.2) that measures the angle between horizontal and the line joining the two points
of contact with the floor’s surface.
