SIGNIFICANCE AND USE
The expanded limits of API MPMS Chapter 11.1–2004/Adjunct to IP 200/04/Adjunct to ASTM D 1250–04 (ADJD1250CD) 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).
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.
Table 2 provides a cross-reference between the historical table designations and the corresponding section in API MPMS Chapter 11.1–2004/Adjunct to IP 200/04/Adjunct to ASTM D 1250–04 (ADJD1250CD). 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.
4.4 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 API MPMS Chapter 11.1–2004/Adjunct to IP 200/04/Adjunct to ASTM D 1250–04 (ADJD1250CD). The user should refer to the appropriate sections of API MPMS Chapter 9 or other appropriate density/hydrometer standards for guidance.

SCOPE
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). 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, Fp, CPL, and CTPL) may be used as specified in other standards.
1.2 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 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 expre...

INTRODUCTION
This guide discusses the use of temperature and pressure volume correction factors for generalized
crude oils, refined products, and lubricating oils, developed jointly by ASTM International, the
2
American Petroleum Institute (API) and the Energy Institute.
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. Traditionally, the factors have been listed in tabular format called the
Petroleum Measurement Tables (hence the appearance of this term in the title), and published as an
API Standard/Adjunct to IP 200/Adjunct to ASTM D1250. However, since the 1980 revision the
actual standard has been a set of implementation procedures, not printed tables nor simply a set of
equations.
This revised standard, API MPMS Chapter 11.1–2004/Adjunct to IP 200/04/Adjunct to ASTM
D1250–04 (ADJD1250CD), establishes 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). The standard, API MPMS Chapter
11.1–2004/Adjunct to IP 200/04/Adjunct to ASTM D1250–04 (ADJD1250CD), also provides
methods for making conversions to alternate conditions from base conditions and to alternate base
temperatures. Densities can be corrected by using the inverse of the VCF.
See Section 5 for a list of significant changes from Guide D1250–80 (provided in its entirety in
3
Annex A1 ).
USAGE GUIDELINES
The revised standard, API MPMS Chapter 11.1–2004/Adjunct to IP 200/04/Adjunct to ASTM
D1250–04 (ADJD1250CD), is effective upon the date of publication and supersedes the previous
edition of the standard/adjunct(s). However, due to the nature of the changes in the revised
standard/adjunct(s), it is recognized that guidance concerning an implementation period may be
needed in order to avoid disruptions within the industry and ensure proper application. As a result, it
is recommended that the revised standard/adjunct(s) be used on all new applications no later than two
years after the publication date (May 2004). An application for this purpose is defined as the point
where the calculation is applied.
Once the revised standard/adjunct(s) is implemented in a particular application, the previous
standard will no longer be used in that application.
If an existing application complies with the previous standard/adjunct(s) (as referenced in Annex
3
A1 ), then it shall be considered in compliance with the revised standard/adjunct(s).
However, the use of the API MPMS Chapter 11.1–2004/Adjunct to IP 200/04/Adjunct to ASTM
D1250–04 (ADJD1250CD) 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.
