Designation:D709517Standard Test Method forRapid Determination of Corrosiveness to Copper fromPetroleum Products Using a Disposable Copper Foil Strip1This standard is issued under the fixed designation D7095;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.INTRODUCTIONThis test method is similar in nature to the Test Method D130 test method,but involves three majordifferences.Firstly,a single-use copper foil strip is used in place of the Test Method D130 multi-usecopper strip.Secondly,a different polishing technique is used in preparing the copper foil strip,whichuses a commercially available scouring-pad in place of the initial and final polishing techniquesdescribed in Test Method D130.Thirdly,this test method involves a shorter analysis time of 45 minfor all product types as compared to the Test Method D130 method requirements,which are longer;for example,two or three hours.1.Scope*1.1 This test method covers the determination of the corro-siveness to copper of aviation gasoline,aviation turbine fuel,automotive gasoline,natural gasoline,or other hydrocarbonshaving a vapor pressure no greater than 124 kPa(18 psi),cleaners(for example,Stoddard solvent),kerosine,diesel fuel,distillate fuel oil,lubricating oil,and other petroleum products.1.2 The values stated in SI units are to be regarded as thestandard.1.2.1 ExceptionThe values in parentheses are provided forinformation only.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,health,and environmental practices and deter-mine the applicability of regulatory limitations prior to use.For specific warning statements,see 6.1,10.1.1,and AnnexA2.1.4 This international standard was developed in accor-dance with internationally recognized principles on standard-ization established in the Decision on Principles for theDevelopment of International Standards,Guides and Recom-mendations issued by the World Trade Organization TechnicalBarriers to Trade(TBT)Committee.2.Referenced Documents2.1 ASTM Standards:2B152/B152M Specification for Copper Sheet,Strip,Plate,and Rolled BarD130 Test Method for Corrosiveness to Copper from Petro-leum Products by Copper Strip TestD396 Specification for Fuel OilsD975 Specification for Diesel Fuel OilsD1655 Specification for Aviation Turbine FuelsD1838 Test Method for Copper Strip Corrosion by LiquefiedPetroleum(LP)GasesD4057 Practice for Manual Sampling of Petroleum andPetroleum ProductsD4177 Practice for Automatic Sampling of Petroleum andPetroleum ProductsD6615 Specification for Jet B Wide-Cut Aviation TurbineFuelE1 Specification for ASTM Liquid-in-Glass Thermometers2.2 ASTM Adjuncts:ASTM Copper Strip Corrosion Standard33.Summary of Test Method3.1 A polished copper foil strip is immersed in a specificvolume of the sample being tested and heated under conditions1This test method is under the jurisdiction of ASTM Committee D02 onPetroleum Products,Liquid Fuels,and Lubricants and is the direct responsibility ofSubcommittee D02.05 on Properties of Fuels,Petroleum Coke and Carbon Material.Current edition approved Oct.1,2017.Published October 2017.Originallyapproved in 2004.Last previous edition approved in 2014 as D7095 04(2014).DOI:10.1520/D7095-17.2For 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.3Available from ASTM International Headquarters.Request Adjunct No.ADJD0130.Names of suppliers in the United Kingdom can be obtained fromEnergy Institute,61 New Cavendish St.,London,WIM 8AR,United Kingdom.OneMaster Standard is held at Energy Institute for reference.*A Summary of Changes section appears at the end of this standardCopyright 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 of temperature and time that are specific to the class of materialbeing tested.At the end of the heating period,the copper foilstrip is removed,washed,and the color and tarnish levelassessed against the ASTM Copper Strip Corrosion Standard.4.Significance and Use4.1 Crude petroleum contains sulfur compounds,most ofwhich are removed during refining.However,of the sulfurcompounds remaining in the petroleum product,some can havea corroding action on variou
