Natural gas — Determination of composition and associated uncertainty by gas chromatography — Part 3: Precision and bias

ISO 6974-3:2018 is an international standard that outlines a gas chromatographic method for determining the composition of natural gas, specifically measuring the content of hydrogen, helium, oxygen, nitrogen, carbon dioxide, and hydrocarbons up to C8 using two packed columns; essentially, it defines a precise way to analyze the components of a natural gas sample using a specific laboratory technique.
