Natural gas. Determination of composition and associated uncertainty by gas chromatography -- Precision and bias
This document describes the precision that can be expected from the *gas chromatographic method* that is set up in accordance with **ISO 6974‑1**.
The stated precision provides values for the magnitude of variability that can be expected between test results when the method described in **ISO 6974‑1** is applied in one or more competent laboratories.
This document also gives guidance on the assessment of bias.
