3、ed 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 volu
4、me 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 Measure
5、ment 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

8、te 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-
9、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 with
10、in 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
11、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 standa
