1.1 The API MPMS Chapter 11.1-2004/Adjunct to IP 200/04/Adjunct to ASTM D 1250-04 (ADJD1250CD) for temperature and pressure volume correction factors for generalized crude oils, refined products, and lubricating oils, provides the algorithm and implementation procedure for the correction of temperature and pressure effects on density and volume of liquid hydrocarbons. Natural gas liquids (NGLs) and liquefied petroleum gases (LPGs) are excluded from consideration.
The combination of density and volume correction factors for both temperature and pressure is collectively referred to in the standard/adjunct(s) as a Correction for Temperature and Pressure of a Liquid (CTPL). The temperature portion of this correction is termed the Correction for the effect of Temperature on Liquid (CTL), also historically known as VCF (Volume Correction Factor). ASTM D1250-08, The pressure portion is termed the Correction for the effect of Pressure on Liquid (CPL). As this standard will be applied to a variety of applications, the output parameters specified in this standard/adjunct(s) (CTL, F, CPL, and CTPL) may be used as specified in other standards.
1.2 ASTM D1250-08, Including the pressure correction in API MPMS Chapter 11.1-2004/Adjunct to IP 200/04/Adjunct to ASTM D 1250-04 (ADJD1250CD) represents an important change from the “temperature only” correction factors given in the 1980 Petroleum Measurement Tables. However, if the pressure is one atmosphere (the standard pressure) then there is no pressure correction and the standard/adjunct(s) will give CTL values consistent with the 1980 Petroleum Measurement Tables.
1.3 ASTM D1250-08, API MPMS Chapter 11.1-2004/Adjunct to IP 200/04/Adjunct to ASTM D 1250-04 (ADJD1250CD) covers general procedures for the conversion of input data to generate CTL, Fp, CPL, and CTPL values at the user specified base temperature and pressure (Tb, Pb). Two sets of procedures are included for computing volume correction factor: one set for data expressed in customary units (temperature in °F, pressure in psig); the other for the metric system of units (temperature in °C, pressure in kPa or bar). ASTM D1250-08, In contrast to the 1980 Petroleum Measurement Tables, the metric procedures require the procedure for customary units be used first to compute density at 60°F. This value is then further corrected to give the metric output. The metric procedures now incorporate the base temperature of 20°C in addition to 15°C.
1.4 ASTM D1250-08, The procedures recognize three distinct commodity groups: crude oil, refined products, and lubricating oils. A procedure is also provided for determining volume correction for special applications where the generalized commodity groups’ parameters may not adequately represent the thermal expansion properties of the liquid and a precise thermal expansion coefficient has been determined by experiment.

A redline document is a quick and easy way to compare all changes between the active standard and the previous version. A redline document shows additions, deletions, and other formatting or content changes between the two versions. Redlines will save you time and ensure that you know exactly what changes were made from one version to the next
