Standard Terminology Relating to Gaseous Fuels
SCOPE
1.1 This terminology standard covers the compilation of terminology developed by Committee D03 on Gaseous Fuels. It does not include terms, definitions, abbreviations, acronyms, and symbols specific to only a single D03 standard in which they appear. These terms, definitions, abbreviations, acronyms, and symbols are used in:
1.1.1 The sampling of gaseous fuels,
1.1.2 The analysis of gaseous fuels for composition and various other physical properties, and
1.1.3 Other practices related to the processing, transmission, and distribution of gaseous fuels.
1.2 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

3.1 Definitions:
absolute pressure, n—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
