Be sure to familiarize yourself with ASTM F and choose the best concrete moisture test method for the job. Depress SET Button to check settings.
10 Guidelines for ASTM F Compliance
We have people who use the Rapid RH on shallow pours. In f2170-1 moisture measurement systems are evolving rapidly as a result of ATSM F and reflect the industry realities of the concrete installation business.
As concrete dries, moisture migrates from the bottom of the slab to the surface where it can evaporate away.
F requires three test holes for the first ft 2 and, at least, one additional hole for each additional ft 2. Click here for a moisture meter. October 27, at In-situ probe concrete testing: Thanks for the reply, Patrick. Logically then, moisture levels at the bottom of a slab will read higher from those at the surface. If i have an area of approx sq ft and have done the required testing for the area, and 5 fail and 3 pass does the whole area f2170-11
10 Guidelines for ASTM F2170 Preparation and Testing
The instruments have proven to perform well in rough mill environments with day-to-day usage. Without studying pages and pages of operation manuals: Does the finish roof product have specifications for testing the concrete deck? Many contractors use vapor barriers directly under the slab to slow moisture permeation. As any professional knows, ASTM standards are established to help guide industry testing and also to help ensure standardized best practices to protect both the installer and the consumer.
The test hole depth is not a fixed depth, but it must be calculated based on slab thickness and number of drying sides: Without it, even a well-dried and functioning foundation can end up with concrete slab moisture problems. Contact My Account 0 items April 3, at How do you handle this problem? This process requires time and quantifiable concrete moisture measurements to verify. At this point, if one test fails, they all fail.
Jason, I appreciate this means to contact you. September 6, at April 7, at 3: First, I have to state that F is specified for interior applications that are under consistent ambient air controls. Section 9 of the standard requires that both the slab and the ambient air above it must be at service conditions for a minimum of 48 hours before testing. The depth is calculated to the bottom of the test hole the location of astmm installed Qstm sensor or probe.
I hope this helps. In this way, in situ measurement provides a composite picture of overall slab moisture levels, and provides the data necessary to make business decisions regarding flooring installations.
Ligno-Tec RH Concrete Test Conforms to ASTM F
Preparation Confirm your test method equipment meets specifications. Instrument turns itself off automatically.
Meeting this standard provides the groundwork for limiting moisture-related flooring problems and the many liabilities and mitigation problems that can result from excess moisture. Thanks for the question. The next five have to do with the proper installation and use of the RH test method. June 8, at 1: Measuring aatm is our expertise.
Once adtm find out the methodology they require to meet warranty, I would reach out to someone within RCI in your area to conduct the tests. You consent to our cookies if you continue to use our website. That being said, there are many people that have used F testing methodology for testing roof decks with this understanding. For flooring and concrete professionals, ASTM F provides the standard for using relative humidity RH testing when measuring moisture content in concrete slabs.
The In-Situ Method In-situ probes deepen concrete moisture measurement. If you forward to 1: We also will not be shipping on these days, but will resume shipping on Tuesday, January 2nd. Lignomat has designed the RH BluePeg Probe, sleeves, cable and RH concrete moisture meter for a simple and fail-proof measuring procedure.

Know the required depth of the test holes. Note that the liner requirements have been updated and the hole is to be fully lined to meet the ASTM standard. September 2, at 9:
