Full Description

1.1These test methods2 cover the determination of the properties of flexible membranes to be used as vapor retarders in contact with earth under concrete slabs, against walls, or as ground cover in crawl spaces. The test methods are applicable primarily to plastic films and other flexible sheets. The materials are not intended to be subjected to sustained hydrostatic pressure. The procedures simulate conditions to which vapor retarders may be subjected prior to and during installation, and in service.

1.2The test methods included are:

	Section
Water-Vapor Transmission of Material as Received	7
Water-Vapor Transmission after Wetting and Drying and after Long- Time Soaking	8
Tensile Strength	9
Resistance to Puncture	10
Resistance to Plastic Flow and Elevated Temperature	11
Effect of Low Temperatures on Flexibility	12
Resistance to Deterioration from Organisms and Substances in Con- tacting Soil	13
Resistance to Deterioration from Petroleum Vehicles for Soil Poisons	14
Resistance to Deterioration from Exposure to Ultraviolet Light	15
Resistance to Flame Spread	16
Report	17

1.3The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.

1.4This 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.

1.5This 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.
