Standard Test Method for Indicating Moisture in Concrete by the Plastic Sheet Method

SIGNIFICANCE AND USE
Capillary moisture in the concrete may be detrimental to the performance of certain coating systems that cannot tolerate moisture on or within the surface boundary.
This test method is used prior to the application of coatings on concrete.
SCOPE
1.1 This test method is used to indicate the presence of capillary moisture in concrete.
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. For specific caution statements, see Section 4.
