SIGNIFICANCE AND USE
5.1 The expanded limits of the Adjunct for VCF are defined in a mixture of terms of customary and metric units. Table 1 shows the defining limits and their associated units in bold italics. Also shown in Table 1 are the limits converted to their equivalent units (and, in the case of the densities, other base temperatures).
5.2 Note that only the precision levels of the defining values shown in Table 1 are correct. The other values showing converted units have been rounded to the significant digits shown; as rounded values, they may numerically fall just outside of the actual limits established by the defining values.
5.3 Table 2 provides a cross-reference between the historical table designations and the corresponding section in the Adjunct for VCF. Note that procedure paragraphs 11.1.6.3 (U.S. customary units) and 11.1.7.3 (metric units) provide methods for correcting on-line density measurements from live conditions to base conditions and then to compute CTPL factors for continuous volume corrections to base conditions.
5.4 When a glass hydrometer is used to measure the density of a liquid, special corrections must be made to account for the thermal expansion of the glass when the temperature is different from that at which the hydrometer was calibrated. The 1980 CTL Tables had generalized equations to correct glass hydrometer readings, and these corrections were part of the printed odd-numbered tables. However, detailed procedures to correct a glass hydrometer reading are beyond the scope of the Adjunct for VCF. The user should refer to the appropriate sections of API MPMS Chapter 9 or other appropriate density/hydrometer standards for guidance.
5.5 The set of correlations given in the Adjunct for VCF is intended for use with petroleum fluids comprising either crude oils, refined products, or lubricating oils that are single-phase liquids under normal operating conditions. The liquid classifications listed here are typical terms used in the industry, ...
SCOPE
1.1 This guide provides information related to the algorithm and implementation procedure but does not contain the full set of algorithms. The algorithms, instructions, procedures, and examples are located in the associated supplementary adjuncts. The Adjunct for Volume Correction Factors (VCF) 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 in this standard but may be found in API MPMS Chapter 11.2.4/GPA 8217 Temperature Correction for NGL and LPG. As this Adjunct for VCF will be applied to a variety of applications, the output parameters of CTL, Fp, CPL, and CTPL may be used as specified in other standards.
1.2 Including the pressure correction in the Adjunct for VCF 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 The Adjunct for VCF 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).
Note 1: 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 va...

INTRODUCTION
This guide, ASTM D1250, provides information related to the algorithm and implementation
procedure for the correction of temperature and pressure effects on density and volume of liquid
hydrocarbons as outlined in API MPMS Chapter 11.1, Physical Properties Data—Temperature and
Pressure Volume Correction Factors for Generalized Crude Oils, Refined Products, and Lubricating
Oils. The algorithms and implementation procedure are published in an adjunct (supplementary)
product called the Adjunct for Volume Correction Factors (VCF).
ASTM D1250 is not theAPI standard and all instructions, procedures, and examples for calculating
volume correction factors for generalized crude oils, refined products, and lubrication oils are found
in the standard, API MPMS Chapter 11.1-2004, Addendum 1{2007, and Addendum 2{2019.
The volume correction factors, in their basic form, are the output of a set of equations derived from,
and based on, empirical data relating to the volumetric change of hydrocarbons over a range of
temperatures and pressures. Prior to 2004, the factors were listed in tabular format called ASTM
D1250, Petroleum Measurement Tables and published as anAPI Standard Chapter 11.1/Adjunct to IP
200/Adjunct to ASTM D1250. However, the current standard, API MPMS Chapter 11.1{2004,
Addendum 1{2007, and Addendum 2{2019 replaced the previous printed tables.
This current Adjunct for VCF establishes a set of implementation procedures for crude oils, liquid
refined products, and lubricating oils, by which volume measurements taken at any temperature and
pressure (within the range of the standard) can be corrected to an equivalent volume at base/standard
conditions, normally 15 °C, 60 °F, or 20 °C, by use of a volume correction factor (VCF). TheAdjunct
for VCF also provides methods for making conversions to alternate conditions from base condition
and to alternate base temperatures. Densities can be corrected by using the inverse of the VCF.
USAGE GUIDELINES
The current Adjunct for VCF is effective upon the date of publication and supersedes the previous
edition of the standard/adjunct(s). Once the current year version of the standard(s) and adjunct are
implemented in a particular application, the previous versions should no longer be used in that
application. However, the use of the standard(s) and adjunct remains voluntary, and the decision on
when to utilize a standard is an issue that is subject to the negotiations between the parties involved
in the transaction.

2019 UPDATE
Some minor modifications to the API MPMS Chapter 11.1-2004/Adjunct to IP 200/04/Adjunct to
ASTM D1250–04Addendum 1-2007 have been issued asAddendum 2-2019. These modifications to
the adjunct necessitated a realignment with ASTM Standard Guide D1250, hence a –19 version has
been approved and published.
