Standard Test Method for Determining Floor Tolerances Using Waviness, Wheel Path and Levelness Criteria (Metric)

Importancia y uso:

5.1 This test method provides statistical and graphical information concerning floor surface profiles.

5.2 Results of this test method are for the purpose of the following: 

5.2.1 Establishing compliance of random or fixed-path trafficked floor surfaces with specified tolerances;

5.2.2 Evaluating the effect of different construction methods on the waviness of the resulting floor surface;

5.2.3 Investigating the curling and deflection of concrete floor surfaces;

5.2.4 Establishing, evaluating, and investigating the profile characteristics of other surfaces; and

5.2.5 Establishing, evaluating, and investigating the levelness characteristics of surfaces.

5.3 Application: 

5.3.1 Random Traffic—When the traffic patterns across a floor are not fixed, two sets of survey lines approximately equally spaced and at right angles to each other shall be used. The survey lines shall be spaced across the test section to produce lines of approximately equal total length, both parallel to and perpendicular to the longest test section boundary. Limits are specified in 7.2.2 and 7.3.2.

5.3.2 Defined Wheel Path Traffic—For surfaces primarily intended for defined wheel path traffic, only two wheel paths and the initial transverse elevation difference (“side-to-side”) between wheels shall be surveyed.

5.3.3 Time of Measurement—For new concrete floor construction, the elevation measurements shall be made within 72 h of final concrete finishing. For existing structures, measurements shall be taken as appropriate.

5.3.4 Elevation Conformance—Use is restricted to shored, suspended surfaces.

5.3.5 RMS Levelness—Use is unrestricted, except that it is excluded from use with cambered surfaces and unshored, elevated surfaces.
