ASTM F2170 Update Allows Official RH Test Results After 24 Hours
Rogue River, Ore. -- The international standards organization, ASTM International, published its revised ASTM F2170, Standard Test Method for Determining Relative Humidity in Concrete Floor Slabs Using in situ Probes. The updated standard reduces the mandatory wait period before obtaining official, documentable results from an in situ relative humidity (RH) moisture test performed in concrete floor slabs from 72 hours to 24 hours.
This significant reduction in wait time allows contractors and flooring installers to take action on RH test results a full two days earlier than the ASTM F2170 standard previously allowed. It also should enable contractors and flooring professionals to accelerate their construction and remodeling projects accordingly.
