Relative Humidity Test Results in Just 24 Hours
Responding to new science, ASTM updated F2170


Responding to new science, ASTM updated F2170 (Standard Test Method for Determining Relative Humidity in Concrete Floor Slabs...) reducing the mandatory wait period before getting official results from an RH moisture test of concrete slabs from 72 hours to 24 hours. This was possible after a study showed that readings at the one-day mark were statistically equal to readings at the three-day juncture.

As seen in LC/DBM magazine, March 2018.
