Designation:D116018Standard Test Method forDistillation of Petroleum Products at Reduced Pressure1This standard is issued under the fixed designation D1160;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 covers the determination,at reducedpressures,of the range of boiling points for petroleum productsand biodiesel that can be partially or completely vaporized at amaximum liquid temperature of 400 C.Both a manual methodand an automatic method are specified.1.2 In cases of dispute,the referee test method is the manualtest method at a mutually agreed upon pressure.1.3 The values stated in SI units are to be regarded asstandard.The values given in parentheses after SI units areprovided for information only and are not considered 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,health,and environmental practices and deter-mine the applicability of regulatory limitations prior to use.For specific warning statements,see 6.1.4,6.1.8.1,10.11,andA3.2.1.1.5 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:2D613 Test Method for Cetane Number of Diesel Fuel OilD1193 Specification for Reagent WaterD1250 Guide for Use of the Petroleum Measurement TablesD1298 Test Method for Density,Relative Density,or APIGravity of Crude Petroleum and Liquid Petroleum Prod-ucts by Hydrometer MethodD4052 Test Method for Density,Relative Density,and APIGravity of Liquids by Digital Density MeterD4057 Practice for Manual Sampling of Petroleum andPetroleum ProductsD4177 Practice for Automatic Sampling of Petroleum andPetroleum ProductsD6300 Practice for Determination of Precision and BiasData for Use in Test Methods for Petroleum Products andLubricants3.Terminology3.1 Definitions of Terms Specific to This Standard:3.1.1 atmospheric equivalent temperature(AET),nthetemperature converted from the measured vapor temperatureusing Eq A7.1.The AET is the expected distillate temperatureif the distillation was performed at atmospheric pressure andthere was no thermal decomposition.3.1.2 end point(EP)or final boiling point(FBP),nthemaximum vapor temperature reached during the test.3.1.3 initial boiling point(IBP),nthe vapor temperaturethat is measured at the instant the first drop of condensate fallsfrom the lower end of the condenser section drip tip.3.1.3.1 DiscussionWhen a chain is attached to the drip tipthe first drop will form and run down the chain.In automaticapparatus,the first drop detection device shall be located asnear to the lower end of the drip tip as practical.3.1.4 spillover point,nthe highest point of the lowerinternal junction of the distillation column and the condensingsection of the vacuum-jacketed column assembly.4.Summary of Test Method4.1 The sample is distilled at an accurately controlledpressure between 0.13 kPa and 6.7 kPa(1 mm and 50 mm Hg)under conditions that are designed to provide approximatelyone theoretical plate fractionation.Data are obtained fromwhich the initial boiling point,the final boiling point,and adistillation curve relating volume percent distilled and atmo-spheric equivalent boiling point temperature can be prepared.1This test method is under the jurisdiction of ASTM Committee D02 onPetroleum Products,Liquid Fuels,and Lubricants and is the direct responsibility ofSubcommittee D02.08 on Volatility.Current edition approved July 1,2018.Published August 2018.Originallyapproved in 1951.Last previous edition approved in 2015 as D1160 15.DOI:10.1520/D1160-18.2For 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.*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 5.Significance and Use5.1 This test method i
