Designation:D6382/D6382M99(Reapproved 2022)Standard Practice forDynamic Mechanical Analysis and Thermogravimetry ofRoofing and Waterproofing Membrane Material1This standard is issued under the fixed designation D6382/D6382M;the number immediately following the designation indicates theyear of original adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of lastreapproval.A superscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 This practice covers test procedures and conditions thatare applicable when Test Methods D5023,D5024,D5026,D5279,and D5418 are used for conducting dynamic mechani-cal analysis of roofing and waterproofing membrane material inthree-point bending,compression,tension,torsion,and dualcantilever modes,respectively.The specific method is selectedby the analyst and depends on the membrane material and theoperating principles of the individual instrument used for theanalysis.1.2 This practice covers test procedures and conditions thatare applicable when Test Method E1131 is used for conductingthermogravimetry of roofing and waterproofing membranematerial.1.3 Membrane materials include bituminous built-uproofing,polymer-modified bitumen sheets,vulcanized rubbers,non-vulcanized polymeric sheets,and thermoplastics.Themembrane materials can be either nonreinforced or reinforced.1.4 This practice is applicable to new membrane materialsreceived from the supplier,those exposed artificially in thelaboratory or outdoors on an exposure rack,and those sampledfrom field installations.1.5 This practice contains notes which are explanatory andare not part of the mandatory requirements of this practice.1.6 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 nonconformancewith the standard.1.7 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,health,and environmental practices and deter-mine the applicability of regulatory limitations prior to use.1.8 This international standard was developed in accor-dance with internationally recognized principles on standard-ization established in the Decision on Principles for theDevelopment of International Standards,Guides and Recom-mendations issued by the World Trade Organization TechnicalBarriers to Trade(TBT)Committee.2.Referenced Documents2.1 ASTM Standards:2D1079 Terminology Relating to Roofing and WaterproofingD4092 Terminology for Plastics:Dynamic MechanicalPropertiesD5023 Test Method for Plastics:Dynamic Mechanical Prop-erties:In Flexure(Three-Point Bending)D5024 Test Method for Plastics:Dynamic Mechanical Prop-erties:In CompressionD5026 Test Method for Plastics:Dynamic Mechanical Prop-erties:In TensionD5279 Test Method for Plastics:Dynamic Mechanical Prop-erties:In TorsionD5418 Test Method for Plastics:Dynamic Mechanical Prop-erties:In Flexure(Dual Cantilever Beam)E473 Terminology Relating to Thermal Analysis and Rhe-ologyE1131 Test Method for Compositional Analysis by Thermo-gravimetryE1142 Terminology Relating to Thermophysical Properties3.Terminology3.1 DefinitionsFor definitions of terms used in thispractice,refer to Terminologies E473,D1079,D4092,andE1142.4.Summary of Practice4.1 In conducting a dynamic mechanical analysis,the roof-ing or waterproofing membrane specimen is placed in a test1This practice is under the jurisdiction ofASTM Committee D08 on Roofing andWaterproofing and is the direct responsibility of Subcommittee D08.20 on RoofingMembrane Systems.Current edition approved Nov.1,2022.Published November 2022.Originallyapproved in 1999.Last previous edition approved in 2017 as D6382/D6382M 99(2017).DOI:10.1520/D6382_D6382M-99R22.2For 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.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United StatesThis international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for theDevelopment of International Standards,Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade(TBT)Committee.1chamber and subjected to a controlled,increasing temperatureprogram.The temperature range can be from well below(forexample,80 C)to somewhat(for example,50 C)aboveroom temperature.The glass transition temperature,storagemodulus,loss modulus,and damping factor of the specimenare measured.4.2 In conducting a thermogravimetry analysis,th
