This International Standard describes the performance requirements for analysis of treated natural gas of
transmission or pipeline quality in sufficient detail so that the hydrocarbon dewpoint temperature can be
calculated using an appropriate equation of state. It can be applied to gases that have maximum dewpoint
temperatures (cricondentherms) between 0 °C and 50 °C. The pressures at which these maximum dewpoint
temperatures are calculated are in the range 2 MPa (20 bar) to 5 MPa (50 bar). Major components are
measured using ISO 6974 (all parts) and the ranges of components that can be measured are as defined in
ISO 6974-1. The procedure given in this International Standard covers the measurement of hydrocarbons in
the range C5 to C12. n-Pentane, which is quantitatively measured using ISO 6974 (all parts), is used as a
bridge component and all C6 and higher hydrocarbons are measured relative to n-pentane.
