Be sure to familiarize yourself with ASTM F and choose the best concrete moisture test method for the job. Relative humidity RH in a concrete slab can fluctuate with environmental changes. To check the calibration we offer calibration check salts. Know the required depth of the test holes.

ASTM F Explained – ASTM F Information

All cables have easy-to-connect and fail-proof 35mm stereo connectors. I would verify that the hole depths are consistent and that environmental conditions are at service conditions. It has f2170-111 believed that the change in the desiccant weight could be translated into a moisture ratio for the concrete beneath. June 8, at 1: We recommend placing the serial number decal which also helps track certification of each sensor on the corresponding test hole on d2170-11 mapped report.

The standard provides precise guidelines for RH testing methods.


For extended reach, a cable up to 50ft long can be added. For most RH testing systems, this includes cleaning any debris out of the test hole and inserting the necessary liner in the hole. The RH BluePeg probe uses a hi-accuracy sensor with a short acclimation time. These requirements for the standard apply regardless of the RH test method ast used.

10 Guidelines for ASTM F2170 Preparation and Testing

Map your sensor count and location. Click here for a moisture meter.

General contractors must bear in mind two interactive processes when they are looking at construction schedules: The total area of the slab and the number of test holes must be recorded on your report.

Operation is that easy! ASTM F formally recognizes the use of in situ probes as a means of f217-011 relative humidity testing. This process requires time and quantifiable concrete moisture measurements to verify.

Use up or down buttons to correct settings. UPS peak season may cause delays.

Ligno-Tec RH Concrete Test Conforms to ASTM F

Once you find out the methodology they require to meet warranty, I would reach out to someone within RCI in your area to conduct the tests. December 27, at 3: How do you handle this problem? Each test hole must be drilled to the depth determined at Step 5 above section 10 of ASTM F and properly prepared. Does the finish roof product have specifications for testing the concrete deck? April 7, at 3: Skip to content Concrete slab moisture is a major cause of concrete flooring failure.


The first thing I would look at is the assembly that you are installing. And f2107-11 can still be an issue at grade so concrete foundations must be designed to include proper moisture drainage. Concrete absorbs water vapor from the air under high ambient humidity; concrete releases more water vapor when the humidity of the surrounding air is low.

Now is a good time to buy! This will NOT be valid for ASTM compliance, but can certainly provide a target timeline for schedule decisions or for choosing alternate adhesive or flooring options that might have higher moisture tolerances.

Note that the liner requirements have been updated and the hole is to be fully lined to meet the ASTM standard.

F requires three test holes for the first ft 2 and, at least, one additional f22170-11 for each additional ft 2. RH Testing and Reporting Drill and prepare the test holes. That being said, I have heard a couple of different methods people are using.
