Designation:E1993/E1993M98(Reapproved 2013)1Standard Specification forBituminous Water Vapor Retarders Used in Contact withSoil or Granular Fill Under Concrete Slabs1This standard is issued under the fixed designation E1993/E1993M;the number immediately following the designation indicates the yearof original adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.A superscript epsilon()indicates an editorial change since the last revision or reapproval.1NOTEUnits information was editorially corrected in May 2013.1.Scope1.1 This specification covers bituminous water vapor retard-ers for use 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 either SI units or inch-pound unitsare to be regarded separately as standard.The values stated ineach system may not be exact equivalents;therefore,eachsystem shall be used independently of the other.Combiningvalues from the two systems may result in non-conformancewith the standard.1.4 This standard does not purport to address all of thesafety concerns,if any,associated with its use.It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.Referenced Documents2.1 ASTM Standards:2C168 Terminology Relating to Thermal InsulationD828 Test Method for Tensile Properties of Paper andPaperboard Using Constant-Rate-of-ElongationApparatus(Withdrawn 2009)3D1790 Test Method for Brittleness Temperature of PlasticSheeting by ImpactD5147/D5147M Test Methods for Sampling and TestingModified Bituminous Sheet MaterialE96/E96M Test Methods for Water Vapor Transmission ofMaterialsE154/E154M Test Methods for Water Vapor Retarders Usedin Contact with Earth Under Concrete Slabs,on Walls,oras Ground CoverE631 Terminology of Building Constructions3.Terminology3.1 DefinitionsFor definitions of terms used in thisspecification,see Terminologies C168 and E631.3.2 Definitions of Terms Specific to This Standard:3.2.1 perm,nthe time rate of water vapor migrationthrough a material or a construction of one grain per hour,square foot,inch of mercury pressure difference.3.2.1.1 DiscussionIf a specification states that a one permlimit is required,the same flow rate will be obtained from thefollowing relationships:41 perm=1 grain/(h ft2 in Hg)inch pound=57.2 1012kg/(Pa s m2)SI Fundamental Units=57.2 ng/(Pa s m2)SI Frequently Used=0.66 g/24h m2 mm HgSI has been used but is nowobsolete3.2.2 vapor retarder,n(formally vapor barrier)a materialor construction that impedes the transmission of water vaporunder specified conditions.3.2.3 water vapor permeability,na property of materialwhich is water vapor permeance through unit thickness.Sincematerials that provide resistance to vapor flow are never usedin unit thickness,the evaluation of both materials and construc-tions used herein is permeance.4.Sampling4.1 Each sampling shall consist of sufficient material toprovide at least five specimens for the tests listed in Section 7.5.Specifying Information5.1 Specification for materials shall include the following:5.1.1 This specification number,and1This specification is under the jurisdiction of ASTM Committee E06 onPerformance of Buildingsand are the direct responsibility of Subcommittee E06.21onServiceability.Current edition approved April 1,2013.Published May 2013.Originallyapproved in 1998.Last previous edition approved in 2008 as E1993 98(2008).DOI:10.1520/E1993_E1993M-98R13E01.2For referenced ASTM standards,visit the ASTM website,www.astm.org,orcontact ASTM Customer Service at serviceastm.org.For Annual Book of ASTMStandards volume information,refer to the standards Document Summary page onthe ASTM website.3The last approved version of this historical standard is referenced onwww.astm.org.4See 3.2.3 of Test Methods E154/E154M.This conversion is based on atemperature of 0C 32F and not on an environmental temperature of 23C73.4F.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 5.1.2 Performance requirements,if any,for special condi-tions(see 7.6).6.Lap Sealing6.1 This producer shall provide supplier/seller/installer withinstructions for lap sealing,including minimum width of lap,method of sealing,and shall either supply or recommendspecified suitable products for lap sealing.7.Properties7.1 The bituminous membrane water vapor retarder shallconsist of asphaltic materials reinforced with multiple plies ofsuitable fabric.The bituminous vapor retarder shall meet therequirements listed in Table 1 as well as those outlined below.7.2 PermeanceMaterial,including lap seals,shall con-form to the requirements listed in Table 1 under the followingconditions when tested according to Test Methods E154/E154M,Section 7(
