  1. ‘NORMAL CUBIC METER’ (m³n) shall mean a cubic meter , the reference conditions of measurement being 0 degrees Celsius at a pressure of 101.325 kilopascals and a free of water vapour these conditions.
  2. ‘RELATIVE DENSITY’ (relative molecular weight), shall mean the ratio of the average molecular weight of gas to that of air (28.97)
  3. ‘WOBBE INDEX’ shall mean the index obtained when the energy content of the gas in (MJ/m³n) is divided by the square root of the relative density of the gas calculated by WNo = HHV
