Designation:D22507StandardSpecification forAsphalt Shingles(Organic Felt)Surfaced With MineralGranules1This standard is issued under the fixed designation D225;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.This standard has been approved for use by agencies of the Department of Defense.1.Scope1.1 This specification covers asphalt roofing in shingleform,composed of single or multiple thicknesses of organicfelt saturated and coated on both sides with asphalt andsurfaced on the weather side with mineral granules.1.2 Shingles meeting this specification are intended to beapplied with a headlap of not less than 51 mm(2 in.).1.3 The values stated in SI units are to be regarded as thestandard.The values given in parentheses are for informationonly.2.Referenced Documents2.1 ASTM Standards:2D228 Test Methods for Sampling,Testing,and Analysis ofAsphalt Roll Roofing,Cap Sheets,and Shingles Used inRoofing and WaterproofingD1079 Terminology Relating to Roofing and WaterproofingD1370 Test Method for Contact Compatibility BetweenAsphaltic Materials(Oliensis Test)D3161 Test Method for Wind-Resistance of AsphaltShingles(Fan-Induced Method)D3462 Specification for Asphalt Shingles Made from GlassFelt and Surfaced with Mineral GranulesD4977 Test Method for Granule Adhesion to Mineral Sur-faced Roofing by AbrasionE108 Test Methods for Fire Tests of Roof Coverings3.Terminology3.1 DefinitionsFor definitions of terms,see TerminologyD1079.3.2 Definitions of Terms Specific to This Standard:3.2.1 weather-exposed portionany portion of a shingleexposed to the weather when applied in accordance with themanufacturers instructions,excluding any part of the upperportion exposed by a cutout.4.Classification4.1 Type IUniform or nonuniform thickness shingles ofany style(see Table 1).4.2 Type IIIUniform or nonuniform thickness shingles ofany style(see Table 1).5.Materials and Manufacture5.1 In the process of manufacture,a single thickness of dryfelt shall be impregnated with a hot asphaltic saturant,thencoated on both sides with a hot asphaltic coating,and finallysurfaced on the weather side with mineral granules.Laminatedshingles need have mineral granules only on the weather sideof the laminate.The reverse side shall be covered with asuitable material to prevent the shingles from sticking togetherin the package.5.2 The felt shall be produced primarily from organic fibers.The surface of the felt shall be uniform and relatively smooth.Upon splitting or tearing on the bias,the felt shall appearreasonably free of lumps of underbeaten stock and particles offoreign substances.5.3 The asphaltic coating may be compounded with a finemineral stabilizer substantially insoluble in water.6.Physical Requirements6.1 During handling and application,the shingles shall notcrack at ambient temperatures above 10C(50F)nor be sosticky at temperatures below 60C(140F)as to cause tearingor other material damage upon being unpacked.6.2 Loss and Behavior on HeatingThe shingles shallconform to the physical requirements prescribed in Table 2.7.Dimensions,Mass,and Permissible Variations7.1 The style and dimensions of the shingles shall be asagreed upon by the purchaser and the seller as part of the1This 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 Nov.1,2007.Published December 2007.Originallyapproved in 1925.Last previous edition approved in 2004 as D225 04.DOI:10.1520/D0225-07.2For 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 StatesNOTICE:This standard has either been superseded and replaced by a new version or withdrawn.Contact ASTM International(www.astm.org)for the latest information1purchase contract.Shingles shall not vary more than 66 mm(14in.)from nominal dimensions established for each style andsize.7.2 The shingles shall conform to the masses prescribed inTable 1.8.Workmanship,Finish,and Appearance8.1 The felt(each felt in a laminated shingle)shall bethoroughly and uniformly saturated and shall show no unsatu-rated spots at any point upon cutting 50-mm(2-in.)wide stripsat random across the entire shingle and splitting them open totheir full length.8.2 The weather side shall be uniform in finish and texture,but may be embossed to simulate a wood grain.The mineralgranules shall be uniformly distributed in a smooth layer overthe entire surface and shall be firmly embedded in the
