7、format called ASTMD1250,Petroleum Measurement Tables and published as an API Standard Chapter 11.1/Adjunct to IP200/Adjunct to ASTM D1250.However,the current standard,API MPMS Chapter 11.12004,Addendum 12007,and Addendum 22019 replaced the previous printed tables.This current Adjunct for VCF establi
8、shes a set of implementation procedures for crude oils,liquidrefined products,and lubricating oils,by which volume measurements taken at any temperature andpressure(within the range of the standard)can be corrected to an equivalent volume at base/standardconditions,normally 15 C,60 F,or 20 C,by use
9、of a volume correction factor(VCF).The Adjunctfor VCF also provides methods for making conversions to alternate conditions from base conditionand to alternate base temperatures.Densities can be corrected by using the inverse of the VCF.USAGE GUIDELINESThe current Adjunct for VCF is effective upon th
