DS DSEN SO 6976 2005-SEP-06 Natural gas - Calculaton of calorfc values densty relatve densty and Wobbe ndex from composton
This 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.
