Overview
ISO 14532:2014, titled Natural Gas - Vocabulary, is an international standard published by ISO that establishes a comprehensive set of terms, definitions, symbols, and abbreviations related to the natural gas industry. This second edition consolidates and harmonizes terminology used across various standards, ensuring consistency and clarity in communication within this vital sector. Developed by ISO/TC 193 and integrating inputs from European and national standards, along with the IGU Dictionary of the Gas Industry, ISO 14532:2014 covers all aspects of natural gas terminology.
This standard is essential for professionals involved in natural gas production, processing, measurement, distribution, and quality management, fostering understanding and interoperability in technical documentation and operations worldwide.
Key Topics
ISO 14532:2014 covers a broad range of specialized vocabulary arranged by industry-related topics:
-
General Conditions: Definitions of natural gas types such as raw gas, substitute natural gas (SNG), manufactured gas, lean gas, rich gas, wet gas, sour gas, dry gas, compressed natural gas (CNG), liquefied natural gas (LNG), biogas, biomethane, and biomass. This section clarifies gas composition, origin, and energy content distinctions.
-
Pipeline Network: Terms describing pipeline infrastructure components like pipeline grids, local distribution systems (LDS), custody transfer points, and transfer stations, essential for understanding natural gas transmission and distribution logistics.
-
Measurement Methods: Definitions related to methods for measuring natural gas properties, including absolute measurement, direct and indirect measurement, relative measurement, and related concepts such as lower and upper range values, and span. Specific measurement techniques like gas chromatography and potentiometric methods provide detailed analysis tools.
-
Sampling and Analytical Systems: Vocabulary covering sampling approaches and the analytical instruments used for gas analysis ensures clarity in quality determination.
-
Physical and Chemical Properties: Standardized terms for physical and chemical characteristics of natural gas help unify descriptions across industries.
-
Interchangeability and Odorization: Definitions related to the suitability of substitute gases for pipeline use and the addition of odorants for safety and detection.
-
Thermodynamic Properties: Terms related to the energy and thermodynamic behavior of natural gas under different conditions, critical for processing and transportation.
Annexes include comprehensive indices, symbols, units, and a bibliography supporting reference and study.
