Designation:D3617/D3617M17Standard Practice forSampling and Analysis of Built-Up Roof Systems DuringApplication1This standard is issued under the fixed designation D3617/D3617M;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.This standard has been approved for use by agencies of the U.S.Department of Defense.1.Scope1.1 This practice is a guide for removing specimens forbuilt-up bituminous roof systems during application,but beforethe application of flood coating and top surfacing,for deter-mining the approximate quantities of the components and thepossible presence of moisture,or dry spots between plies,inthe field.Components may consist of:1.1.1 Insulation,when part of the roof membrane system,1.1.2 Plies of roofing felt,1.1.3 Interply layers of bituminous material,and1.1.4 Top coating,if present,before any surfacing aggregatehas been applied.1.2 This practice is applicable to both 914-mm 36-in.and1000-mm 3938-in.wide felt rolls.1.3 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.1.4 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:2D226/D226M Specification for Asphalt-Saturated OrganicFelt Used in Roofing and WaterproofingD227/D227M Specification for Coal-Tar-Saturated OrganicFelt Used in Roofing and WaterproofingD250 Standard Specification for Asphalt-Saturated AsbestosFelt Used in Roofing and Waterproofing(Withdrawn1991)3D2178/D2178M Specification forAsphalt Glass Felt Used inRoofing and WaterproofingD2626/D2626M Specification for Asphalt-Saturated andCoated Organic Felt Base Sheet Used in RoofingD3158 Specification for Asphalt Saturated and Coated Or-ganic Felt Used in Roofing(Withdrawn 1983)3D3378 Specification for Asphalt-Saturated and Coated As-bestos Felt Base Sheet Used in Roofing(Withdrawn1985)33.Sampling3.1 Unless otherwise specified,take at least one specimenfor each separate roof,plus one for each 929 m210 000 ft2;take specimens at random.3.2 If deficiencies are indicated in the membrane,additionalPractice D3617/D3617M test cuts shall be taken at fourlocations diagonally3 m 10 ft in each directionfrom theoriginal test cut and examined in the same manner as theoriginal test cut was examined.4.Test Specimen4.1 Sweep the surface of the membrane clean where eachtest specimen will be taken.4.2 For determining approximate quantities of components,cut a 300-by 300-mm 12-by 12-in.specimen from themembrane using a template(Fig.1).4.2.1 If the membrane is adhered to the insulation,removethe membrane from the adhering insulation.4.2.2 If the membrane is adhered directly to the roof deck,estimate the quantity of bitumen remaining on the deck afterthe specimen is removed.1This 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 Jan.15,2017.Published January 2017.Originallyapproved in 1977.Last previous edition approved in 2016 as D3617/D3617M 16.DOI:10.1520/D3617_D3617M-17.2For 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.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.1 4.3 For the purpose of determining the felt spacing,cut a100-by 111-mm 4-by 44-in.rectangular specimen from themembrane,using a template(Fig.1)placed at right angles tothe long dimension of the felts.4.4 Identify each specimen by location and record thepresence of insulation or the estimated quantity of bitumenremaining on the deck.4.5 If practicable,return the cut membrane specimen to itsoriginal location in the roof.Make adequate repairs to theroofing system,using at least the same number of felt plies asthe origi
