Designation:D8807(Reapproved 2013)American Association StateHighway and Transportation Officials StandardAASHTO No:T72Method 304Federal TestMethod Standard No.791bReplaces Method 4285 of Federal TestMethod Standard No.141AStandard Test Method forSaybolt Viscosity1This standard is issued under the fixed designation D88;the number immediately following the designation indicates the year of originaladoption or,in the case of revision,the year of last revision.Anumber in parentheses indicates the year of last reapproval.Asuperscriptepsilon()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 test method covers the empirical procedures fordetermining the Saybolt Universal or Saybolt Furol viscositiesof petroleum products at specified temperatures between 21and 99C(70 and 210F).A special procedure for waxyproducts is indicated.NOTE1Test Methods D445 and D2170 are preferred for the deter-mination of kinematic viscosity.They require smaller samples and lesstime,and provide greater accuracy.Kinematic viscosities may be con-verted to Saybolt viscosities by use of the tables in Practice D2161.It isrecommended that viscosity indexes be calculated from kinematic ratherthan Saybolt viscosities.1.2 The values stated in SI units are to be regarded as thestandard.The values given in parentheses are for informationonly.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:2D93 Test Methods for Flash Point by Pensky-MartensClosed Cup TesterD117 Guide for Sampling,Test Methods,and Specificationsfor Electrical Insulating Oils of Petroleum OriginD140 Practice for Sampling Bituminous MaterialsD244 Test Methods and Practices for Emulsified AsphaltsD445 Test Method for Kinematic Viscosity of Transparentand Opaque Liquids(and Calculation of Dynamic Viscos-ity)D2161 Practice for Conversion of Kinematic Viscosity toSaybolt Universal Viscosity or to Saybolt Furol ViscosityD2170 Test Method for Kinematic Viscosity of Asphalts(Bitumens)D4057 Practice for Manual Sampling of Petroleum andPetroleum ProductsD4177 Practice for Automatic Sampling of Petroleum andPetroleum ProductsE1 Specification for ASTM Liquid-in-Glass ThermometersE11 Specification for Woven Wire Test Sieve Cloth and TestSievesE102 Test Method for Saybolt Furol Viscosity of BituminousMaterials at High Temperatures3.Terminology3.1 Definitions:3.1.1 Furolan acronym of“Fuel and road oils.”3.1.2 Saybolt Furol viscositythe corrected efflux time inseconds of 60 mL of sample flowing through a calibrated Furolorifice under specified conditions.The viscosity value isreported in Saybolt Furol seconds,abbreviated SFS,at aspecified temperature.3.1.3 Saybolt Universal viscositythe corrected efflux timein seconds of 60 mL of sample flowing through a calibratedUniversal orifice under specified conditions.The viscosityvalue is reported in Saybolt Universal seconds,abbreviatedSUS,at a specified temperature.4.Summary of Test Method4.1 The efflux time in seconds of 60 mL of sample,flowingthrough a calibrated orifice,is measured under carefullycontrolled conditions.This time is corrected by an orificefactor and reported as the viscosity of the sample at thattemperature.1This test method is under the jurisdiction ofASTM Committee D08 on Roofingand Waterproofing and is the direct responsibility of Subcommittee D08.05 onSolvent-Bearing Bituminous Compounds for Roofing and Waterproofing.Current edition approved May 1,2013.Published May 2013.Originallyapproved in 1921.In 1923,combined with former Methods D47.Last previousedition approved in 2007 as D88 07.DOI:10.1520/D0088-07R13.2For 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 5.Significance and Use5.1 This test method is useful in characterizing certainpetroleum products,as one element in establishing uniformityof shipments and sources of supply.5.2 See Guide D117 for applicability to mineral oils used aselectrical insulating oils.5.3 The Saybolt Furol viscosity is approximately one tenththe Saybolt Universal viscosity,and is recommended forcharacterization of petroleum products such as fuel oils andother residual materials having Saybolt Universal viscositiesgreater than 1000 s.5.4 Determination of the Saybolt Furol viscosity of bitumi-nous materials at higher temperatures is covered by TestMethod E102.6.Apparatus6.1 Saybolt Viscometer and Bath,as shown in Fig.1 anddescribed in A
