VCF

Volume Correction Factor (VCF): the numerical value determined by laboratory analysis or by standardized computer arithmetic that when multiplied by the Gross Observed Volume at tank temperature results in the volume of the product at its standard temperature (15oC or 60oF). The factors applicable for bands of API (relative density) and temperature are available in standard tables booklets or may be computed using a standardized format. If the VCF is below 1 it is shown accurate to 5 places of decimal otherwise it is shown in 4 places of decimal.
