1、Designation: E 1993 98 (Reapproved 2008)Standard Specification forBituminous Water Vapor Retarders Used in Contact withSoil or Granular Fill Under Concrete Slabs1This standard is issued under the fixed designation E 1993; the number immediately following the designation indicates the year oforiginal
2、 adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This specification covers bituminous water vapor retard-ers for use
3、 in contact or granular fill under concrete slabs.1.2 The specified tests are conducted on new materials andmaterials that have been conditioned or exposed to simulatepotential service conditions.1.3 The values stated in SI units are to be regarded asstandard. The values given in parentheses are pro
