Abstract: ISO 15112 is just a management standard, so a series of supporting standards are needed in the implementation process of energy metering, to solve the problems such as selection of analysis and measurement methods, construction of reference measurement instrument, preparation and application of reference gas mixtures, establishment of traceability guidelines and evaluation of uncertainty, etc. A lot of experimental studies and on-site determination have been carried out and a series of achievements have been obtained since GB/T 22723 was released in China. But many important standards have not been formed and carried out yet, which seriously affect the basic research and technology development related to energy metering. Considering foreign advanced standards propelling science and technology tangibility, it is suggested that relevant departments should give full attention to the following three aspects of work: ①pay close attention to the construction of reference calorimeter; ②accelerate the development of high accuracy, multicomponent RGM applicable to energy metering; ③speed up the conversion of ISO and other foreign advanced standards related to natural gas analysis traceability and uncertainty evaluation.
