ASTM E1155: Standard Test Method for Determining FF Floor Flatness and FL Floor Levelness Numbers
DOD Adopted ANSI Approved Approved
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-Acomplete metric companion to Test Method E1155 has been developed, Test Method E1155M; therefore, no metric equivalents are shown in this test method.
