THE AMERICAN PETROLEUM INSTITUTE (API) has joined forces with Flow-Cal to develop, support and distribute the standard and code for API’s Manual of Petroleum Measurement Standards, Chapter 11 – Physical Properties Data, Section 1 – Temperature and Pressure Volume Correction Factors for Generalized Crude Oils, Refined Products, and Lubricating Oils.
This standard establishes a procedure for crude oils, liquid refined products, and lubricating oils through which density measurements taken at any temperature and pressure can be corrected to an equivalent density at the base conditions. The standard also provides a method for making a conversion to alternate base temperatures.
