The constituting gases of the mixtures shall have at least the following purities:

N2 : 99%

CH4: 95%	with a total content of hydrogen, carbon monoxide and oxygen below 1 % and a total content of nitrogen and carbon dioxide below 2%

The Wobbe Index is the ratio of the calorific value of a gas per unit volume and the square root of its relative density under the same reference conditions:

with	Hgas = calorific value of the fuel in MJ/m3 at 0°C

air = density of air at 0°C

gas = density of fuel at 0°C

The Wobbe Index is said to be gross or net according to whether the calorific value uses is the gross or net calorific value."
