Non-destructive moisture meters are now widely used in determining moisture levels in concrete, gypsum concrete and other types of floor slabs. A new ASTM International standard qualifies the types of meter suitable for this purpose and provides guidelines for how, where and when such moisture meters are used and what limitations exist.

The new standard, ASTM F2659, Guide for Preliminary Evaluation of Comparative Moisture Condition of Concrete, Gypsum Concrete and Other Floor Slabs and Screeds Using a Non-Destructive Electronic Moisture Meter, was developed by Subcommittee F06.40 on Practices, part of ASTM International Committee F06 on Resilient Floor Coverings.

“ASTM F2659 is very useful as a fast and easy preliminary standard because the user can take multiple tests, getting instant readings across the slab in a short time,” says Sean Fallon, an F06.40 member. Fallon notes that the new standard can be used by anyone who needs to be concerned with the moisture condition of a floor slab, including flooring installer, consultants and inspectors, and material manufacturers and suppliers.

The subcommittee invites all interested parties to participate in the further development of ASTM F2659.
