3、termine surface flatness and levelness by calculatingwaviness indices for survey lines and surfaces, elevation differences of defined wheel paths, and levelness indices using SI units.NOTE 1This test method is the companion to inch-pound Test Method E1486.NOTE 2This test method was not developed for
4、, and does not apply to clay or concrete paver units.1.1.1 The purpose of this test method is to provide the user with floor tolerance estimates as follows:1.1.1.1 Local survey line waviness and overall surface waviness indices for floors based on deviations from the midpoints ofimaginary chords as
5、they are moved along a floor elevation profile survey line. End points of the chords are always in contact withthe surface. The imaginary chords cut through any points in the concrete surface higher than the chords.1.1.1.2 Defined wheel path criteria based on transverse and longitudinal elevation di

7、 survey line to a specified slope for eachsurvey line.1.1.2 The averages used throughout these calculations are the root mean squares, RMS (that is, the quadratic means).
