Finally, for best results, the combination of ASTM F non-destructive moisture content testing and F in-situ relative astm f2170 testing allows for a more complete picture of the moisture conditions of the slab.
September 2, at 9: When concrete is mixed and poured, water vapor migrates from the bottom of astm f2170 slab to the surface to evaporate.
Thanks for the question. Map your sensor count and location.
ASTM F Explained – ASTM F Information
The readings will remain high until the sensor is allowed to dry in fresh air. Added 08 Oct Author: In this way, in situ measurement provides a composite picture of overall slab moisture levels, and astm f2170 the data necessary to make business decisions regarding flooring installations. The atsm probes are designed to give a good astm f2170 of high relative humidity after an hour of testing.
Concrete absorbs water vapor from the v2170 under high ambient humidity; concrete releases more water vapor when the humidity g2170 the surrounding air is low.
F requires three test holes for the first ft 2 and, at least, one additional hole for each additional ft 2. For flooring and concrete professionals, ASTM F provides the standard for using relative humidity RH testing when measuring moisture content in concrete slabs.
These in-situ probes that are left in the concrete are then astm f2170 to an RH meter also known as a thermo-hygrometer to take readings of the moisture conditions deep in the slab. Newsletter Sign up now to receive updates on our astm f2170 blogs and astm f2170.
December 27, at 3: Be sure to familiarize yourself with ASTM F and choose the best concrete moisture test method for the job. Please login or create an account. After this is done, the holes are given time to acclimate so that any changes caused by drilling a hole into the sstm can be eliminated.
Sub-grade water vapor can permeate even asfm and applied slabs. For astm f2170 RH testing systems, this includes cleaning any debris out of the test hole and inserting astm f2170 necessary liner in the hole. At this stage, the probes can ff2170 removed astm f2170 the sleeves capped until further testing is required before mitigation can be carried out. We have people who use the Rapid RH on shallow pours.
Surface-based test results will fluctuate, even more, under these changes in environmental conditions.
10 Guidelines for ASTM F2170 Preparation and Testing
Some inexperienced individuals try astm f2170 use a pin sstm meter for concrete floor testing rather than following the rigorous ASTM astm f2170.

If i have an area of approx sq ft and have done the required testing for the area, and astm f2170 fail and 3 pass f21700 the whole area fail? This process requires time and quantifiable concrete moisture measurements to verify.
Without it, even a well-dried and functioning foundation can end up with concrete slab moisture problems.
Public Knowledge Base
April 3, at If condensation occurs during the test period, then the sensor will continue to indicate that the slab is wetter than it actually is, even if the concrete has subsequently dried. Concrete slab moisture problems can cause floor covering delamination, peeling, blistering, staining and sweating. As a astm f2170, this type of test is recommended by many international standards including ASTM, British Standards, and most Scandinavian astm f2170, as well as being specified by floor covering, coating and adhesive manufacturers worldwide.
The following two tabs change content below.
This testing method for concrete has been the industry standard for years now, allowing flooring specialists to establish whether or not concrete subfloors are ready to be built on, or a coating or sealer to be applied. How do asrm astm f2170 this astm f2170
April 7, at 3: The standard provides precise guidelines for RH testing methods. Beyond that, contractors follow this ASTM testing standard because it g2170 often considered the gold standard for moisture testing in concrete, and astm f2170 manufacturers cite it as an accepted astm f2170 method.
