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.

1. 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 SI units are to be regarded as standard. The 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.

2. Referenced Documents (purchase separately) The documents listed below are referenced within the subject standard but are not provided as part of the standard.
