This standard stipulates the method of measuring the calorific value of town gas with "Junker type water flow calorimeter" and the method of measuring the relative density of gas with "Bunsen-Schilling type gas relative density meter". This standard is applicable to town gas with high calorific value lower than 62800kJ/m.
