Abstract
This International Standard specifies methods for the
calculation of the superior calorific value, inferior
calorific value, density, relative density and Wobbe
index of dry natural gases, natural gas substitutes and
other combustible gaseous fuels, when the composition
of the gas by mole fraction is known. The
methods provide a means of calculating the properties
of the gas mixture at commonly used metric reference
conditions.
The methods of calculation require values for various
physical properties of the pure components; these
values are provided in tables and their sources are
identified.
Methods are given for estimating the precision of
calculated properties.
