Designation:D663008Standard Guide forLow Slope Insulated Roof Membrane AssemblyPerformance1This standard is issued under the fixed designation D6630;the number immediately following the designation indicates the year oforiginal 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 guide lists test methods intended to establish aminimum level of performance for insulated roof membraneassemblies,and lists pertinent design guidelines and installa-tion methods in a unified manner.Material tests and evalua-tions are included with and without roof insulation.1.2 It is not possible to establish a precise correlationbetween laboratory tests on roof assemblies and natural weath-ering due to variations in geographical climate,design,mate-rial and installation.1.3 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 requirements prior to use.2.Referenced Documents2.1 ASTM Standards:2D95 Test Method for Water in Petroleum Products andBituminous Materials by DistillationD2523 Practice for Testing Load-Strain Properties of Roof-ing MembranesD4434 Specification for Poly(Vinyl Chloride)Sheet RoofingD4637 Specification for EPDM Sheet Used In Single-PlyRoof MembraneD4798 Practice for Accelerated Weathering Test Conditionsand Procedures for Bituminous Materials(Xenon-ArcMethod)D4799 Practice for Accelerated Weathering Test Conditionsand Procedures for Bituminous Materials(FluorescentUV,Water Spray,and Condensation Method)D5019 Specification for Reinforced CSM(ChlorosulfonatedPolyethylene)Sheet Used in Single-Ply Roof Membrane(Withdrawn 2011)3D5147 Test Methods for Sampling and Testing ModifiedBituminous Sheet MaterialD5601 Test Method for Tearing Resistance of Roofing andWaterproofing Materials and Membranes(Withdrawn2002)3D5602 Test Method for Static Puncture Resistance of Roof-ing Membrane SpecimensD5635 Test Method for Dynamic Puncture Resistance ofRoofing Membrane SpecimensD5849 Test Method for Evaluating Resistance of ModifiedBituminous Roofing Membrane to Cyclic Fatigue(JointDisplacement)E96/E96M Test Methods for Water Vapor Transmission ofMaterials2.2 ASCE Standard:ASCE-7 Minimum Design Loads for Buildings and OtherStructures42.3 ANSI/SPRI Standard:ANSI/SPRI RP-4 Wind Design Guide for Ballasted SinglePly Roof Systems53.Terminology3.1 roof assembliesthe weathering or waterproofing ma-terial,whether film,flexible membrane,semi-flexible mem-brane,factory or field manufactured;the underlying substrateincluding insulation(if used)above or below the membrane,orboth;supporting deck structure and method of attachment ofthe entire assembly.Low slope roof assemblies may be up to25%slope.Some roof assemblies may accommodate higherslopes.3.2 performancethe ability of the roof system as designed,manufactured,and installed to provide adequate levels ofexpected service life in terms of watertightness,thermal1This guide is under the jurisdiction of ASTM Committee D08 on Roofing andWaterproofing and is the direct responsibility of Subcommittee D08.20 on RoofingMembrane Systems.Current edition approved March 15,2008.Published July 2008.Originallyapproved in 2001.Last previous edition approved in 2001 as D6630 01.DOI:10.1520/D6630-08.2For 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.4Available from American Society of Civil Engineers(ASCE),1801 AlexanderBell Dr.,Reston,VA 20191,http:/www.asce.org.5Available from American National Standards Institute and Single Ply RoofingInstitute,200 Reservoir St.,Suite 309A,Needham,MA 02194.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 protection,and condensation control,while being maintain-able.Live loading of the roof system may also occur.4.Significance and Use4.1 Aroof assembly must work as a system.Any componentof the roof assembly demonstrating an inherent weakness orinability to perform will diminish the roof system performanceand service life expected.This guide lists minimum perfor-mance attributes required of low slope roof assemblies.Prod-ucts not previously used as roof membrane materials requireadditional tests beyond the scope of this document.This guideis not intended for use on in-service roofing materials.Roofmembranes and other components should conform to ASTMproduct standards,if available.5.Roof Design Classifications5.1 Type of Construction:ClassConstructionI NewNewII ReplaceRemove exis
