This part of ISO 6974 describes the process required to determine the uncertainty associated with the mole fraction for each component from a natural gas analysis in accordance with ISO 6974‑1.
Abstract
Overview
ISO 6974-2:2012, "Natural gas - Determination of composition and associated uncertainty by gas chromatography - Part 2: Uncertainty calculations", defines the procedure to calculate the associated with each component mole fraction from a natural‑gas gas‑chromatography analysis carried out in accordance with . It covers Steps 9 and 10 of the workflow: calculation of uncertainties of processed mole fractions and the determination of expanded uncertainty for reporting.
