Designation:E115514Standard Test Method forDetermining FFFloor Flatness and FLFloor LevelnessNumbers1This standard is issued under the fixed designation E1155;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.Asuperscript 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.Scope1.1 This test method covers a quantitative method of mea-suring floor surface profiles to obtain estimates of the floorscharacteristic FFFlatness and FLLevelness Face Floor ProfileNumbers(F-Numbers)using the inch-pound system of units.NOTE1Acomplete metric companion to Test Method E1155 has beendeveloped,Test Method E1155M;therefore,no metric equivalents areshown in this test method.1.2 The text of this test method references notes andfootnotes that provide explanatory material.These notes andfootnotes(excluding those in tables and figures)shall not beconsidered as requirements of this test method.1.3 The values stated in inch-pound units are to be regardedas standard.No other units of measurement are included in thisstandard.1.4 This standard does not purport to address all of thesafety concerns,if any,associated with its use.It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.Referenced Documents2.1 ASTM Standards:2E1155M Test Method for Determining FFFloor Flatness andFLFloor Levelness Numbers(Metric)2.2 ACI Standard:3ACI 117-90 Standard Specifications for Tolerances for Con-crete Construction and Materials3.Terminology3.1 Definitions of Terms Specific to This Standard:3.1.1 elevationheight,altitude,vertical location in space.Elevation measurements are always made parallel to thedirection of gravity.3.1.2 flateven,plane,homoloidal,free of undulation.3.1.2.1 DiscussionFor 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.Thecurvature value is the difference between successive elevationdifferences.The mean and standard deviation of all thecurvature values for a given test section are then convertedaccording to the equations in this test method to get thedimensionless FFFlatness Number.3.1.3 floor profilometera Type I device(see 6.1.1)thatproduces a continuous record of the elevation of a single pointmoving along a line on the floors surface.3.1.4 horizontallevel,normal to the direction of gravity.3.1.5 inclinometera Type II device(see 6.1.2)that mea-sures the angle between horizontal and the line joining the twopoints of contact with the floors surface.3.1.6 levelhorizontal,normal to the direction of gravity.3.1.6.1 DiscussionFor the purposes of this test method,levelness will be measured by collecting elevation differencesat points spaced 10 ft apart and that will be described by the FLLevelness number(dimensionless).3.1.7 longitudinal differential floor profilometer,na TypeII device(see 6.1.2)that produces a continuous record of theelevation difference between two points moving along a line onthe floors surface,which two points remain separated by afixed distance.3.1.8 sample measurement linea sample measurement lineshall consist of any straight line on the test surface along whichmeasurements are taken,with the limitations listed in 7.3.3.1.9 sign conventionwhere up is the positive direction;down is the negative direction.Consequently,the higher thereading point,the more positive its hivalue,and the lower thereading point,the more negative its hivalue.Similarly,theelevation difference from a low point to a high point(that is,an1This test method is under the jurisdiction of ASTM Committee E06 onPerformance of Buildings and is the direct responsibility of Subcommittee E06.21on Serviceability.Current edition approved April 1,2014.Published July 2014.Originallyapproved in 1987.Last previous edition approved in 2008 as E1155 96(2008).DOI:10.1520/E1155-14.2For referenced ASTM standards,visit the ASTM website,www.astm.org,orcontact ASTM Customer Service at serviceastm.org.For Annual Book of ASTMStandards volume information,refer to the standards Document Summary page onthe ASTM website.3Available from American Concrete Institute(ACI),P.O.Box 9094,FarmingtonHills,MI 48333-9094,http:/www.concrete.org.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 uphill difference)is positive,while the elevation differencefrom a high point to a low point(that is,a downhill difference)is negative.3.1.10 test sectiona test section consists of any subdivi-sion of the test surface with the limitations listed in 7.2.3.1.11 test surfaceon any one building level,the entirefloor area of interest constitutes the test surfac
