Designation:D125008(Reapproved 2013)1Designation:200/08Standard Guide forUse of the Petroleum Measurement Tables1This standard is issued under the fixed designation D1250;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.1NOTEAdjunct ADJD1250-E-PDF information was corrected editorially in October 2015.INTRODUCTIONThis guide discusses the use of temperature and pressure volume correction factors for generalizedcrude oils,refined products,and lubricating oils,developed jointly by ASTM International,theAmerican Petroleum Institute(API)and the Energy Institute.2The volume correction factors,in their basic form,are the output of a set of equations derived from,and based on,empirical data relating to the volumetric change of hydrocarbons over a range oftemperatures and pressures.Traditionally,the factors have been listed in tabular format called thePetroleum Measurement Tables(hence the appearance of this term in the title),and published as anAPI Standard/Adjunct to IP 200/Adjunct to ASTM D1250.However,since the 1980 revision theactual standard has been a set of implementation procedures,not printed tables nor simply a set ofequations.This revised standard,API MPMS Chapter 11.12004/Adjunct to IP 200/04/Adjunct to ASTMD125004(ADJD1250-E-PDF),establishes procedures for crude oils,liquid refined products,andlubricating oils,by which volume measurements taken at any temperature and pressure(within therange of the standard)can be corrected to an equivalent volume at base/standard conditions,normally15C,60F or 20C,by use of a volume correction factor(VCF).The standard,API MPMS Chapter11.12004/Adjunct to IP 200/04/Adjunct to ASTM D125004(ADJD1250-E-PDF),also providesmethods for making conversions to alternate conditions from base conditions and to alternate basetemperatures.Densities can be corrected by using the inverse of the VCF.See Section 5 for a list of significant changes from Guide D125080(provided in its entirety inAnnex A13).USAGE GUIDELINESThe revised standard,API MPMS Chapter 11.12004/Adjunct to IP 200/04/Adjunct to ASTMD125004(ADJD1250-E-PDF),is effective upon the date of publication and supersedes the previousedition of the standard/adjunct(s).However,due to the nature of the changes in the revisedstandard/adjunct(s),it is recognized that guidance concerning an implementation period may beneeded in order to avoid disruptions within the industry and ensure proper application.As a result,itis recommended that the revised standard/adjunct(s)be used on all new applications no later than twoyears after the publication date(May 2004).An application for this purpose is defined as the pointwhere the calculation is applied.Once the revised standard/adjunct(s)is implemented in a particular application,the previousstandard will no longer be used in that application.If an existing application complies with the previous standard/adjunct(s)(as referenced in AnnexA13),then it shall be considered in compliance with the revised standard/adjunct(s).However,the use of the API MPMS Chapter 11.12004/Adjunct to IP 200/04/Adjunct to ASTMD125004(ADJD1250-E-PDF)remains voluntary,and the decision on when to utilize a standard isan issue that is subject to the negotiations between the parties involved in the transaction.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 2007 UPDATESome minor modifications to the API MPMS Chapter 11.12004/Adjunct to IP 200/04/Adjunct toASTM D125004(ADJD1250-E-PDF)have been issued in Addendum 1-2007.These modificationsto the adjunct necessitated a realignment withASTM Standard Guide D1250,hence an-07 version hasbeen approved and published.1.Scope1.1 The API MPMS Chapter 11.12004/Adjunct to IP 200/04/Adjunct to ASTM D125004(ADJD1250-E-PDF)for tem-perature and pressure volume correction factors for generalizedcrude oils,refined products,and lubricating oils,provides thealgorithm and implementation procedure for the correction oftemperature and pressure effects on density and volume ofliquid hydrocarbons.Natural gas liquids(NGLs)and liquefiedpetroleum gases(LPGs)are excluded from consideration.Thecombination of density and volume correction factors for bothtemperature and pressure is collectively referred to in thestandard/adjunct(s)as a Correction for Temperature and Pres-sure of a Liquid(CTPL).The temperature portion of thiscorrection is termed the Correction for the effect of Tempera-ture on Liquid(CTL),also historically known as VCF(VolumeCorrection Factor).The pressure portion is termed the Correc-tion for the effect of Pressure on Liquid(CPL).As this standardwill be applied to a variety of applications,the output param
