ASTM F formally recognizes the use of in situ probes as a means of conducting relative humidity testing. In fact The Standard The In-Situ Method In-situ concrete moisture testing places sensors, or probes, inside the slab itself . This test method covers the quantitative determination of percent relative testing. The ASTM F standard represents a fundamental change in how. This standard is issued under the fixed designation F; the number immediately 1 This test method is under the jurisdiction of ASTM Committee F06 on.

Learn how your comment data is processed. October 31, at Once you find out the methodology they require to meet warranty, I would reach standrd to someone within RCI in your area to conduct the tests. That being said, I have heard a couple of different methods people are using.

April 3, at Can you please 2f170 me know your recommendation on this? I would verify that the hole depths are consistent and that environmental conditions are at service conditions. RH Testing and Reporting Drill and prepare the test holes. Section 11 of ASTM F details stnadard requirements of each report, including test hole location, dates and times of measurements, RH reading, temperature reading, and any other conditions that might impact the RH reading see section 11 for complete reporting requirements.


For flooring and concrete professionals, ASTM F provides the standard for using relative humidity RH testing when measuring moisture content in concrete slabs. This site uses Akismet to reduce spam.

We also will not be shipping on these days, but will resume shipping on Tuesday, January 2nd. The only thing we recommend is that you ensure that there is a good seal between the sensor body and the concrete wall.

Standatd our checklist to record and report the RH readings. Surface-based test results will fluctuate, even more, under these changes in environmental conditions. Make sure your calibration is up to date. While any professional must understand the exact requirements of standard F the most recent versionthe following are 10 guidelines to help ensure that you have met the criteria laid out in ASTM F Check job site conditions.

Thanks for the reply, Patrick.

10 Guidelines for ASTM F Compliance

January 9, at Leave a Reply Cancel reply Your email address will not be published. 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.

Concrete slab moisture is a major cause of concrete flooring failure. Many contractors use vapor barriers directly under the slab to slow moisture permeation.

10 Guidelines for ASTM F2170 Preparation and Testing

The depth is calculated to the bottom of the test hole the location of the installed RH sensor or probe. Contact My Account 0 items This website uses cookies. Map your sensor count and location. Be sure to familiarize yourself with ASTM F and choose the best concrete moisture test method for the job.


Your email address will not be published. Some calibration restrictions may apply, so read the standard carefully to be sure your test equipment qualifies for the most recent standard.

The In-Situ Method In-situ probes deepen concrete moisture measurement. The standard provides precise guidelines for RH testing methods.

Without it, even a well-dried and functioning foundation can end up with concrete slab moisture problems. Each hole must have a liner that isolates the sensor from ambient conditions, and sensors must have NIST-traceable calibration.

F requires three test holes for the first ft 2 and, at least, one additional hole for each additional ft 2. 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. At this point, if one test fails, they all fail.
