(Specification)Standard Specification for Bituminous Water Vapor Retarders Used in Contact with Soil or Granular Fill Under Concrete Slabs
Standard Specification for Bituminous Water Vapor Retarders Used in Contact with Soil or Granular Fill Under Concrete Slabs
ABSTRACT
This specification covers the properties and tests for bituminous membrane water vapor retarders used in contact with soil or granular fill under concrete slabs. Tests may be conducted on both new materials and materials that have been conditioned or exposed to simulate service conditions. The water vapor retarders shall consist of asphaltic materials reinforced with multiple plies of suitable fabric, and shall meet the following property requirements when tested: water vapor permeance; tensile strength; puncture resistance; and thickness. When specifically required by the buyer for use in special conditions, the retarders shall additionally adhere to properties such as resistance to plastic flow and elevated temperatures, effect of low temperature on bending, resistance to deterioration from petroleum vehicle for soil poisons, and resistance to deterioration from exposure to ultraviolet light.
SCOPE
1.1 This specification covers bituminous water vapor retarders for use in contact or granular fill under concrete slabs.
1.2 The specified tests are conducted on new materials and materials that have been conditioned or exposed to simulate potential service conditions.
1.3 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.
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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.5 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.
