|Publication Date:||1 November 2018|
|ICS Code (Natural gas):||75.060|
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.
