(1)  Group H: For suitable gas appliances (e.g. appliance category I2E), shortfalls in the Wobbe index down to WS,n = 43,2 MJ/m3 (12,0 kWh/m3) can be tolerated for limited periods of time in order to avoid supply shortages, with the appliance setting remaining unchanged at WS,n = 54,0 MJ/m3 (15,0 kWh/m3). (40,95 MJ/m3 (15oC)).

(2)  Group L: For suitable gas appliances (e.g. appliance category I2ELL), shortfalls in the Wobbe index down to WS,n = 36,0 MJ/m3 (10,0 kWh/m3) can be tolerated for limited periods of time in order to use natural gases which are rich in inert gases, with the appliance setting remaining unchanged at WS,n = 44,6 MJ/m3 (12,4 kWh/m3). (34,13 MJ/m3 (15oC )).

(3)  Domestic or similar use, as well as uses specified in footnotes (g) and (h); deviations possible for commerce or industry.

(4)  Nominal.

(5)  Only from stationary tank.

(6)  Hydrogen, nitrogen, oxygen and methane.

(7)  For gas appliances in domestic or commercial use, and gas appliances in commercial use in vehicles.

(8)  For gas appliances in caravans, camper vans and boats, as well as gas appliances in commercial use in vehicles .
