Standard Test Methods for Water Vapor Retarders Used in Contact with Earth Under Concrete Slabs, on Walls, or as Ground Cover
|Publication Date:||1 October 2008|
|ICS Code (Concrete and concrete products):||91.100.30|
significance And Use:
In service, vapor retarders may be exposed to a variety of conditions, so no one test will provide evaluations related to performance for all exposures (refer to Guide E 241 and Practice C 755).... View More
In service, vapor retarders may be exposed to a variety of conditions, so no one test will provide evaluations related to performance for all exposures (refer to Guide E 241 and Practice C 755). Neither will all test methods listed be necessary in all evaluations for specific exposures (see 16.2).
Limitations-Prior to use and in service, vapor retarders may be exposed to a variety of conditions so no one test will provide evaluations related to performance for all exposures (refer to Guide E 241 and Practice C 755). Neither will all tests be necessary in all evaluations for specific exposures. Consequently, the tests and required test results shall be agreed upon by the purchaser and the supplier (see 16.2).View Less
1.1 These test methods 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.
1.2 The test methods included are:
|Water-Vapor Transmission of Material as Received||7|
|Water-Vapor Transmission after Wetting and Drying and after Long-|
|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-|
|Resistance to Deterioration from Petroleum Vehicles for Soil Poisons||14|
|Resistance to Deterioration from Exposure to Ultraviolet Light||15|
|Resistance to Flame Spread||16|
1.3 The values stated in SI units are to be regarded as standard. The inch-pound values given in parentheses are provided for information only and are not considered standard.
1.4 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.
