This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.

absolute pressure, n—pressure measured with reference to absolute zero pressure, usually expressed as kPa, mm Hg, bar, or
psia.the pressure relative to an ideal vacuum.
DISCUSSION—
The absolute pressure can be expressed in kPa, mm Hg, bar, psia, etc., as defined by the application.
DISCUSSION—
An ideal vacuum is the best vacuum available using the application.
acid gas, n—natural gas containing high concentrations of hydrogen sulfide or carbon dioxide, or both, which is acidic when
in contact with water or water vapor.
associated gas, n—natural gas, also known as gas-cap gas or dome gas, that overlies and is in immediate contact, but not in
solution, with crude oil in a reservoir.
at-line instrument, n—instrument requiring operator interaction to sample gas directly from the pipeline.
base conditions, n—temperature and pressure conditions at which natural gas volumes are determined for purposes of custody
transfer.
DISCUSSION—
In natural gas measurements, the properties of interest are temperature, pressure, and composition. Assuming ideal gas properties, for simplicity, tables
of pure compounds can be prepared for use in calculating gas properties for any composition at “base conditions.” These “base conditions” are chosen
near ambient.
