Designation:D312/D312M15Standard Specification forAsphalt Used in Roofing1This standard is issued under the fixed designation D312/D312M;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.This standard has been approved for use by agencies of the U.S.Department of Defense.1.Scope1.1 This specification covers four types of asphalt intendedfor use in built-up roof construction,construction of somemodified bitumen systems,construction of bituminous vaporretarder systems,and for adhering insulation boards used invarious types of roof systems.The specification is intended forgeneral classification purposes only,and does not implyrestrictions on the slope at which an asphalt must be used.1.2 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.1.3 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 limitations prior to use.2.Referenced Documents2.1 ASTM Standards:2D5 Test Method for Penetration of Bituminous MaterialsD36 Test Method for Softening Point of Bitumen(Ring-and-Ball Apparatus)D92 Test Method for Flash and Fire Points by ClevelandOpen Cup TesterD113 Test Method for Ductility of Bituminous MaterialsD140 Practice for Sampling Bituminous MaterialsD1079 Terminology Relating to Roofing and WaterproofingD2042 Test Method for Solubility of Asphalt Materials inTrichloroethyleneD3461 Test Method for Softening Point ofAsphalt and Pitch(Mettler Cup-and-Ball Method)D4402 Test Method for Viscosity Determination of Asphaltat Elevated Temperatures Using a Rotational Viscometer3.Materials and Manufacture3.1 The asphalts shall be prepared from crude petroleum.4.Physical Requirements4.1 Asphalts shall be homogeneous and free of water.4.2 Asphalts of each type shall conform to the physicalproperties prescribed in Table 1.5.Sampling and Test Methods5.1 Sample the material and determine the properties enu-merated in this specification in accordance with the followingmethods:5.1.1 SamplingPractice D140.5.1.2 Softening Point See Test Methods D36 or D3461.Incases where a disagreement exists between the purchaser andthe seller,Test Method D36 shall be used as the refereemethod.5.1.3 Flash Point Test Method D92.5.1.4 Penetration Test Method D5.5.1.5 DuctilityTest Method D113.5.1.6 SolubilityTest Method D2042.5.1.7 EVTTest Method D44026.Inspection6.1 Inspection of the material shall be agreed upon betweenthe purchaser and the seller as part of the purchase contract.7.Rejection and Resubmittal7.1 Failure to conform to any of the requirements prescribedin this specification shall constitute grounds for rejection.Incase of rejection,the seller shall have the right to reinspect therejected material and resubmit the lot after removal of thosepackages not conforming to the requirements.8.Packaging and Marking8.1 Asphalt shall be suitably packaged(if not shipped inbulk)to permit acceptance by the carrier and to afford adequateprotection from the normal hazards of handling and shipment.1This specification is under the jurisdiction of ASTM Committee D08 onRoofing and Waterproofing and is the direct responsibility of Subcommittee D08.03on Surfacing and Bituminous Materials for Membrane Waterproofing and Built-upRoofing.Current edition approved Feb.1,2015.Published March 2015.Originallyapproved in 1929.Last previous edition approved in 2006 as D312 00(2006).DOI:10.1520/D0312_D0312M-15.2For 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 States1 8.2 Each container or bill of lading on bulk shipments shallbe plainly marked with the name of the manufacturer or sellerand the ASTM designation and type of product,maximumkettle temperature of 550F,and the lot specific equiviscoustemperature(EVT)for mop and for mechanical spreaderapplication.9.Keywords9.1 asphalt;built-up roof;roofing;softening pointAPPENDIX(Nonmandatory Information)X1.APPLICATION GUIDEX1.1 Asphalt should be applied within the EVT applicationrange for asphalt as described in Terminology D1079.X1.2 At no time should the kettle temperature exceed550F.ASTM International takes no position respecting the validity of any patent
