API MPMS Chapter 11.1-2004/Adjunct to ASTM D1250-04 and IP 200/04 provides general procedures for the conversion of input data to generate the corrected values at the user specified base temperature and pressure using the effect of temperature on the liquid (CTL), the compressibility coefficient (F p ), the correction for the effect of pressure on the liquid (CPL), or the correction for temperature and pressure of a liquid (CTPL), in a form that is consistent with the computation procedures used to generate VCF values. Two sets of procedures are given for computing the volume correction factor: one set for data expressed in U.S. customary units (temperature in degrees Fahrenheit, pressure in pounds per square inch gauge), the other for the metric system of units (temperature in degrees Celsius, pressure in kilopascals). In contrast to API MPMS Chapter 11.1-1980/ASTM D1250-80/IP 200/80, the metric procedures require the procedure for U.S. customary units be used first to compute density at 60 °F. This value is then further corrected to give the metric output.
