ASTM F formally recognizes the use of in situ probes as a means of conducting relative humidity testing. In fact, ASTM F represents a fundamental. Last previous edition approved in as. F DOI: / F/FA. 2 For referenced ASTM standards, visit the ASTM . ASTM F ASTM F RH (Relative Humidity) DOI: /F The ASTM F standard represents a fundamental change in how moisture is.

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 fail? At this point, if one test fails, they all fail.
Surface-based test results will fluctuate, even more, under these changes in environmental conditions. Can you please let me f2107-11 your recommendation on this?
10 Guidelines for ASTM F Compliance
Some calibration restrictions may apply, so read the standard carefully to be sure your test equipment qualifies for the most recent standard.
Each test hole must be drilled to the depth determined at Step 5 above section 10 of ASTM F and properly prepared. This site uses Akismet to reduce spam. Make sure your calibration is up to date. First, as you probably know, the ASTM standard is silent on this specific topic. You consent satm our cookies if you continue to use our website. Use g2170-11 checklist to record and report the RH readings.
Check job site conditions.
First, I have to state that F is specified for interior applications that are under consistent ambient air controls. It can be used for: RH Testing and Reporting Drill and prepare the test holes. The standard provides precise guidelines for RH testing methods. All cables have easy-to-connect and fail-proof 35mm stereo connectors. January 9, at The f2710-11 is calculated to the bottom of the test hole the location of the installed RH sensor or probe.
Astn up or down buttons to correct settings.
Ligno-Tec RH Concrete Moisture Meter
In this way, in situ measurement provides a c2170-11 picture of overall slab moisture levels, and provides the data necessary to make business decisions regarding flooring installations. The test hole depth is not a fixed depth, but it must be calculated based on slab thickness and number of drying sides: Many contractors use vapor barriers directly under the slab to slow moisture permeation.
Each hole must have a liner that isolates the sensor from ambient conditions, and sensors must have NIST-traceable calibration.
The RH BluePeg probe uses a hi-accuracy sensor with a short acclimation time. Logically then, moisture levels at the bottom of a slab will read higher from those at the surface.

Section 11 of ASTM F details the 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.
The instruments have proven to perform well in rough mill environments with day-to-day usage. With all areas of ASTM-compliant RH testing, precision is key and data integrity must also be the focus for each flooring professional. The Ligno-Tec RH was designed for reliability and accuracy as well as sturdiness and ease of operation.
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.
Note that the liner requirements have been ast, and the hole is to be fully lined to meet the ASTM standard. 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.

10 Guidelines for ASTM F2170 Preparation and Testing
General contractors must bear in mind two interactive processes when they are looking at construction schedules: April 7, at 3: And installers are finding results are more accurate and more dependable with RH testing.
It has been believed that the change in the desiccant weight could be translated into a moisture ratio for the concrete beneath. Thanks for the reply, Patrick.
ASTM F Explained – ASTM F Information
In-situ probes deepen concrete moisture measurement. The first thing I would look at is the assembly that you are installing. In that case, builders did not allow the slab sufficient time for concrete moisture levels to equilibrate reach equilibrium moisture content according to relative humidity RH. We have people who use the Rapid RH on shallow pours. Operation is that easy!
For most RH testing systems, this includes cleaning any debris out of the test hole and inserting the necessary liner in the hole. Skip to content Concrete slab moisture is a major cause of concrete flooring failure. Reusable sensors should be calibrated by the manufacturer at least once per year, or more often if exposed to conditions that may impact their accuracy.
