Popis
BS EN ISO 6974-3:2018
This standard BS EN ISO 6974-3:2018 Natural gas. Determination of composition and associated uncertainty by gas chromatography is classified in these ICS categories:
- 75.060 Natural gas
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.
