(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
Moisture permeating from concrete floor slabs affects the performance of flooring systems such as resilient and textile floor coverings and coatings. Manufacturers of such systems generally require moisture testing to be performed before installation on concrete. Internal relative humidity testing is one such method.
Excessive moisture permeating from floor slabs after installation can cause floor covering system failures such as debonding and deterioration of finish flooring and coatings and microbial growth.
Moisture test results indicate the moisture condition of the slab only at the time of the test.
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 and health 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.

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.
ProcedureAfor 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.
