标准范围
This International Standard provides the means for energy determination of natural gas by measurement or bycalculation, and describes the related techniques and measures that are necessary to take. The calculation ofthermal energy is based on the separate measurement of the quantity, either by mass or by volume, of gastransferred and its measured or calculated calorific value. The general means of calculating uncertainties arealso given.Only systems currently in use are described.This International Standard applies to any gas-measuring station from domestic to very large high-pressuretransmission.New techniques are not excluded provided their proven performance is equivalent to, or better than, that ofthose techniques referred to in this International Standard.Gas-measuring systems are not the subject of this International Standard.
