Benefits of the updated standard
The 2018 update to the ASTM F2170 standard can shave two full days off any project timeline. However, it is important specifiers mention the in-situ RH test in project documentation. Otherwise, one cannot know for sure the project team will choose the RH testing method and take advantage of the shorter testing window.
GCs and flooring professionals should be excited about the accelerated timeframe the updated RH test standard allows, as it will help them focus their time and resources more efficiently in getting to project completion. The latest RH test research, combined with the publication of the revised ASTM F2170 standard, gives assurance of being able to plan and act based on a 24-hour waiting period while minimizing the risk of a moisture-related flooring failure down the road. The new 24-hour RH test window is a “win-win” for everyone involved. GCs and flooring contractors can improve their utilization of project resources. Architects and specifiers can be confident the right RH test standards get employed for accurate results within a shorter timeframe. Clients can also enjoy beautiful, resilient concrete floors for years into the future.

How is it important to shave two days off a concrete moisture testing time frame by using one RH test over another type of test when it will take a minimum of 30 to 90 days for concrete to dry to a level that it is even worthwhile to start testing. I agree the RH test is the most reliable concrete moisture test, but it hardly matters in the overall construction schedule that I can get reliable results in one day instead three, when it is going to take 30 to 90 days before it is practical to even start testing. It is more importan to know when to start tresting. Paul Potts
