This part of ISO 6974 gives methods for calculating component mole fractions of natural gas and specifies the
data processing requirements for determining component mole fractions. This part of ISO 6974 provides for
both single and multiple operation methods and either multi-point calibration or a performance evaluation of
the analyser followed by single-point calibration. This part of ISO 6974 gives procedures for the calculation of
the raw and processed (e.g. normalized) mole fractions, and their associated uncertainties, for all components.
The procedures given in this part of ISO 6974 are applicable to the handling of data obtained from replicate or
single analyses of a natural gas sample.
