ASTM WK32398

    New Test Method for Standard Test Method for Measuring Floor Flatness & Pavement Smoothness Using a Straightedge

    (What is a Work Item?)

    Developed by Subcommittee: E06.21 | Committee E06 | Contact Staff Manager


    1. Scope

    This test method provides statistical (and graphical) information concerning floor surface profiles. Results of this test method are used primarily to: 1. Establish compliance of randomly trafficked floor surfaces with specified straightedge tolerances, 2. Evaluate the effect of different construction methods on resulting floor surface flatness and levelness, and 3. Investigate the curling and deflection of floor surfaces. 4. Results of this test method shall not be used to enforce contract flatness and levelness tolerances on those floor installations primarily intended to support the operation of fixed-path vehicle systems (for example, narrow aisle warehouse floors).

    Use of a 10 ft. (3 m) actual straightedge to measure floor flatness is a long-standing approach that is used worldwide. However, the method is time consuming and prone to debate. This standard will incorporate the floor profile data collection equipment developed in the last 30 years, instead of actual straightedges, and evaluating digital data by simulating a straightedge resting upon the floor surface, in an efficient, reproducible manner.

    The title and scope are in draft form and are under development within this ASTM Committee.
