Keywords
concrete, gypsum, wood, level, levelness
Rationale
There is currently no standard for to provide a practice for how to determine floor flatness.
Previous method has consisted of using a 10-foot straight edge. Technologies such as altimeters and electronic levels can produce more accurate measurements.
There is a need for standardization on how these different tools are used to provide more consistent and meaningful data.
Users would include: installers, contractors, inspectors, and end users.
The title and scope are in draft form and are under development within this ASTM Committee.
