Natural gas - Determination of composition and associated uncertainty by gas chromatography - Part 3: Precision and bias
|Publication Date:||1 October 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.
