Natural gas — Determination of composition and associated uncertainty by gas chromatography — Part 4: Guidelines and requirements for gas analysis

Gaz naturel — Détermination de la composition et de l'incertitude associée par chromatographie en phase gazeuse — Partie 4: Lignes directrices et exigences pour l'analyse des gaz

Abstract / scope

This document gives guidance for obtaining the best analysis results possible from a Gas Chromatograph (GC) when analysing natural gas and natural gas substitutes for combined use with the most recent versions of ISO 6974’s part 1, 2 and 3. (Examples are given.)
