ASTM F2170-19a
(Test Method)Standard Test Method for Determining Relative Humidity in Concrete Floor Slabs Using in situ Probes
Standard Test Method for Determining Relative Humidity in Concrete Floor Slabs Using in situ Probes
SIGNIFICANCE AND USE
5.1 Excessive moisture in floor slabs after floor covering has been installed can cause floor covering system failures such as debonding, peaking and deterioration of finish flooring and coatings and microbial growth.
5.2 Manufacturers of such systems generally require moisture testing to be performed before installation on concrete. Internal relative humidity testing is one such method.
5.3 Moisture test results indicate the moisture condition of the slab only at the time of the test and in the specific locations tested.
SCOPE
1.1 This test method covers the quantitative determination of percent relative humidity in concrete slabs for field or laboratory tests.
1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
Specific warnings are given in Section 7, 10.3.2, and 10.4.4.
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

3. Terminology
3.1 Definitions:
3.1.1 relative humidity, n—ratio of the amount of water vapor actually in the air compared to the amount of water vapor required
for saturation at that particular temperature and pressure, expressed as a percentage.
3.1.2 service temperature and relative humidity, n—average ambient air temperature and relative humidity that typically will be
found in a building’s occupied spaces during normal use.
4. Summary of Test Method
4.1 This test method comprises two procedures for forming holes in concrete into which a relative humidity probe is placed.
Procedure A for hardened concrete involves drilling a cylindrical hole in concrete with a rotary hammerdrill, then placing a hollow
sleeve to line the hole. Procedure B is an alternative procedure for fresh concrete, which involves forming a cylindrical hole in
concrete by placing a hollow cylindrical tube in the formwork, then placing and consolidating concrete around the tube. The liner
or tube permits measurement of RH at a specific, well-defined depth in the concrete.
4.2 Methods of probe calibration and factors affecting equilibration are described in Section 8.
