ASTM International Standard Test Method for Determining F F Floor Flatness and F L Floor Levelness Numbers ASTM E1155-96(2008)

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 E 1155 has been developed, Test Method E 1155M; 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 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.
