Designation:D9717b(Reapproved 2022)Designation:15/22Standard Test Method forPour Point of Petroleum Products1,2This standard is issued under the fixed designation D97;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 and is intended for use on anypetroleum product.3A procedure suitable for black specimens,cylinder stock,and nondistillate fuel oil is described in 8.8.Thecloud point procedure formerly part of this test method nowappears as Test Method D2500.1.2 Currently there is no ASTM test method for automatedTest Method D97 pour point measurements.1.3 Several ASTM test methods offering alternative proce-dures for determining pour points using automatic apparatusare available.None of them share the same designation numberas Test Method D97.When an automatic instrument is used,the ASTM test method designation number specific to thetechnique shall be reported with the results.A procedure fortesting the pour point of crude oils is described in Test MethodD5853.1.4 The values stated in SI units are to be regarded asstandard.No other units of measurement are included in thisstandard.1.5 WARNINGMercury has been designated by manyregulatory agencies as a hazardous substance that can causeserious medical issues.Mercury,or its vapor,has been dem-onstrated to be hazardous to health and corrosive to materials.Use caution when handling mercury and mercury-containingproducts.See the applicable product Safety Data Sheet(SDS)for additional information.The potential exists that sellingmercury or mercury-containing products,or both,is prohibitedby local or national law.Users must determine legality of salesin their location.1.6 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.1.7 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:4D117 Guide for Sampling,Test Methods,and Specificationsfor Electrical Insulating LiquidsD396 Specification for Fuel OilsD2500 Test Method for Cloud Point of Petroleum Productsand Liquid FuelsD5853 Test Method for Pour Point of Crude OilsD6300 Practice for Determination of Precision and BiasData for Use in Test Methods for Petroleum Products,Liquid Fuels,and LubricantsD7962 Practice for Determination of Minimum ImmersionDepth and Assessment of Temperature Sensor Measure-ment DriftE1 Specification for ASTM Liquid-in-Glass ThermometersE644 Test Methods for Testing Industrial Resistance Ther-mometersE1137 Specification for Industrial Platinum Resistance Ther-mometersE2877 Guide for Digital Contact Thermometers1This test method is under the jurisdiction of ASTM International CommitteeD02 on Petroleum Products,Liquid Fuels,and Lubricants and is the directresponsibility of ASTM Subcommittee D02.07 on Flow Properties.The technicallyequivalent standard as referenced is under the jurisdiction of the Energy InstituteSubcommittee SC-C-4.Current edition approved Nov.1,2022.Published November 2022.Originallyapproved in 1927,replacing D47.Last previous edition approved in 2017 asD97 17b.DOI:10.1520/D0097-17BR22.This test method was adopted as a joint ASTM-IP Standard in 1965.2This test method has been developed through the cooperative effort betweenASTM and the Energy Institute,London.ASTM and IP standards were approved byASTM and EI technical committees as being technically equivalent but that does notimply both standards are identical.3Statements defining this test and its significance when applied to electricalinsulating oils of mineral origin will be found in Guide D117.4For 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 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
