This Standard specifies the chemical analysis methods of general components and special components, and the testing methods of the calorific value and the specific gravity of the fuel gas and the natural gas; however, it is not applicable to the liquefied petroleum gas and the liquefied natural gas.
The contents of this specification shall be applicable from July 31st, 2008.
