ASTM F2170 STANDARD TEST METHOD PDF
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.

10 Guidelines for ASTM F2170 Preparation and Testing
f1270 F requires three test holes for the first ft 2 and, at least, one additional hole for each additional ft 2. September 6, at Learn how your comment data is processed. Leave a Reply Cancel reply Your email address will not be published.
Many contractors use vapor barriers directly under the slab to slow moisture permeation. All sensors must be calibrated no less than 30 days prior to use. Each test hole must be drilled to the depth determined at Step 5 above section 10 of ASTM F and methof prepared. Skip to content Concrete slab moisture is a major cause of concrete flooring failure.
The depth is calculated to the bottom of the test hole the location of the installed RH sensor or probe.
UPS peak season may cause delays. If not, call their technical team and ask the questions.
ASTM F Explained – ASTM F Information
Jason, I appreciate this means to contact you. June 8, at 1: At this point, if one test fails, they all fail. Concrete slab moisture is standafd major cause of concrete flooring failure. Metjod all areas of ASTM-compliant RH testing, precision is key and data integrity must also be the focus for each flooring professional. Know the required depth of the test holes. How do you handle this problem? 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.
RH Testing and Reporting Drill and prepare the test holes. And moisture can still be an issue at grade so concrete foundations must be designed to include proper moisture drainage. When concrete is mixed and poured, ashm vapor migrates from the bottom of the slab to the surface to evaporate.
The MVER is defined as the rate of water vapor emissions from the surface of concrete and is determined with the use of a desiccant material sealed to the slab surface for a specified time period, then measured.
October 31, at This process requires time and quantifiable concrete moisture measurements to verify.
10 Guidelines for ASTM F Compliance
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. April 3, at 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.
Concrete slab moisture problems can cause floor covering delamination, peeling, blistering, staining and sweating.
The test hole depth is not a fixed depth, but it must be calculated based on slab thickness and number of drying sides:
