Scope

This part of GB/T27894 gives the method for calculating the mole fraction of natural gas components, specifies the requirements for data processing when determining the mole fraction of components, and is applicable to single operation and multiple operation methods, as well as multi-point correction method or pair analysis. The single-point calibration method adopted after the performance evaluation of the instrument. This section gives the raw data and processed data (such as normalization processing) of all component mole fractions and the processing process of their related uncertainties, which is suitable for processing natural gas samples obtained from repeated analysis or single analysis.
