Designation:D350518Standard Test Method forDensity or Relative Density of Pure Liquid Chemicals1This standard is issued under the fixed designation D3505;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 U.S.Department of Defense.1.Scope*1.1 This test method describes a simplified procedure for themeasurement of density or relative density of pure liquidchemicals for which accurate temperature expansion functionsare known.It is restricted to liquids having vapor pressures notexceeding 79 993 Pascal(0.800 bar,600 mm Hg(0.789 atm)at the equilibration temperature,and having viscosities notexceeding 15 cSt at 20C.1.2 Means are provided for reporting results in the follow-ing units:Density g/cm3at 20CDensity g/mL at 20CRelative density 20C/4CRelative density 15.56C/15.56CNOTE1This test method is based on the old definition of1 L=1.000028 dm3(1 mL=1.000028 cm3).In 1964 the General Conference onWeights and Measures withdrew this definition of the litre and declaredthat the word“litre”was a special name for the cubic decimetre,thusmaking 1 mL=1 cm3exactly.NOTE2An alternative method for determining relative density of pureliquid chemicals is Test Method D4052.1.3 In determining the conformance of the test results usingthis method to applicable specifications,results shall berounded off in accordance with the rounding-off method ofPractice E29.1.4 The values stated in SI units are to be regarded asstandard.No other units of measurement are included in thisstandard.1.5 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.Specific hazard statements are given in Section 8,Hazards.1.6 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:2D1193 Specification for Reagent WaterD1555 Test Method for Calculation of Volume and Weightof Industrial Aromatic Hydrocarbons and CyclohexaneD3437 Practice for Sampling and Handling Liquid CyclicProductsD4052 Test Method for Density,Relative Density,and APIGravity of Liquids by Digital Density MeterD6809 Guide for Quality Control and Quality AssuranceProcedures for Aromatic Hydrocarbons and Related Ma-terialsE1 Specification for ASTM Liquid-in-Glass ThermometersE29 Practice for Using Significant Digits in Test Data toDetermine Conformance with SpecificationsE691 Practice for Conducting an Interlaboratory Study toDetermine the Precision of a Test Method2.2 Other Document:OSHA Regulations,29 CFR paragraphs 1910.1000 and1910.120033.Terminology3.1 Definitions:3.1.1 density,nthe mass of material per unit volume at agiven temperature called the“reference temperature.”Weightcorrected to a standard acceleration of gravity and corrected forthe buoyant effect of air is used to measure mass.This methodspecifies the use of a beam balance to determine weight so thatno correction for variation in acceleration of gravity is neces-sary.When a torsion or spring balance is used,such correctionmust be applied.1This test method is under the jurisdiction of ASTM Committee D16 onAromatic,Industrial,Specialty and Related Chemicals and is the direct responsi-bility of Subcommittee D16.04 on Instrumental Analysis.Current edition approved Feb.15,2018.Published May 2018.Originallyapproved in 1976.Last previous edition approved in 2012 as D3505 121.DOI:10.1520/D3505-18.2For 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 U.S.Government Printing Office Superintendent of Documents,732 N.Capitol St.,NW,Mail Stop:SDE,Washington,DC 20401,http:/www.access.gpo.gov.*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 3.1.2 relative density,nthe ratio of the density of them
