Designation:D3462/D3462M10aStandard Specification forAsphalt Shingles Made from Glass Felt and Surfaced withMineral Granules1This standard is issued under the fixed designation D3462/D3462M;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 specification covers asphalt roofing in shingleform,composed of glass felt or felts impregnated and coatedon both sides with asphalt,and surfaced on the weather sidewith mineral granules.This specification is designed for theevaluation of products as manufactured.The test methods,physical requirements,and minimum masses are to be mea-sured immediately after packaging or at a reasonable time,asagreed upon between buyer and seller,after manufacture andbefore installation.Physical and performance requirementsafter application and during in-service use of the productsdescribed herein are beyond the scope of this material speci-fication.1.2 Shingles meeting this specification are intended to beapplied with a headlap of not less than 51 mm(2 in.).1.3 The shingles shall be supplied with a factory-appliedself-sealing adhesive or be designed to be locked togetherduring installation of the shingles.1.4 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.1.5 The following safety hazards caveat pertains only to thetest method described in this specification:This standard doesnot purport to address all of the safety concerns,if any,associated with its use.It is the responsibility of the user of thisstandard to establish appropriate safety and health practicesand determine the applicability of regulatory limitations priorto 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)D228 Test Methods for Sampling,Testing,and Analysis ofAsphalt Roll Roofing,Cap Sheets,and Shingles Used inRoofing and WaterproofingD1079 Terminology Relating to Roofing and WaterproofingD1922 Test Method for Propagation Tear Resistance ofPlastic Film and Thin Sheeting by Pendulum MethodD3161 Test Method for Wind-Resistance of AsphaltShingles(Fan-Induced Method)D4977 Test Method for Granule Adhesion to Mineral Sur-faced Roofing by AbrasionE108 Test Methods for Fire Tests of Roof Coverings3.Terminology3.1 Definitions:3.1.1 For definitions of terms,see Terminology D1079.3.1.2 For testing purposes,under Test Methods D228,glassfelt shall be considered as felt.4.Materials and Manufacture4.1 The glass felt shall be a thin porous sheet composedpredominately of fine glass fibers uniformly deposited in anonwoven pattern.It is permitted to reinforce the glass feltwith random or parallel-oriented glass yarns,or both,which arepermitted to be gathered or twisted,bonded or unbonded.Thefelt shall contain a substantially water-insoluble binding agent.4.2 In the process of manufacture,one or more thicknessesof glass felt shall be impregnated with an asphaltic material.When more than one thickness of felt is used,the mats shall beadhered to each other with a continuous layer of asphaltic1This specification is under the jurisdiction of ASTM Committee D08 onRoofing and Waterproofing and is the direct responsibility of Subcommittee D08.02on Steep Roofing Products and Assemblies.Current edition approved July 1,2010.Published July 2010.Originally approvedin 1983.Last previous edition approved in 2010 as D3462 10.DOI:10.1520/D3462_D3462M-10A.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 material between adjacent felts.The nature of the asphalticmaterial and the thickness of the adhering layers shall ensure afirm bond between adjacent glass felts.The single felt orlaminated felts shall then be coated on both sides with a hotasphaltic coating.4.3 The asphaltic material used to impregnate,laminate,andcoat the glass felt,in any or all of these functions,is permittedto be compounded with a mineral stabilizer.Glass fibers arepermitted to be compounded with the asphalt in addition to,orinstead of,the mineral stabilizer.4.4 All surfaces to be exposed to the weather,when theproduct is properly installed,shall be surfaced with mineralgranules embedded in the asphalt coating.4.5 The reverse side shall be covered with a suitablematerial suc
