International standardization developments of natural gas quality, analytical and test technologies

International Organization for Standardization Natural gas Technical Committees(ISO/TC 193) is mainly engaged in standardization of terminology, quality specifications, methods of measurement, sampling, analysis and test for natural gas and natural gas substitutes (gaseous fuel) in all its facets from production to delivery to all possible end users across national boundaries. ISO/TC 193 also undertakes recognition of work related to natural gas in other technical committees. ISO/TC 193 has drafted and revised 43 international standards since its establishment. With the rapid development of Chinese natural gas industry, as well as the rapid growth of international trade of natural gas, the demands for standardization of natural gas quality and analytical techniques are also growing. This article focused on detailed analysis of the development of international standard system revision projects in natural gas quality specifications and analytical techniques of ISO/TC 193, and proposed the concerned ISO standard projects and our next work ideas, so as to lay foundation for improving our natural gas quality and analytical techniques standard system as soon as possible and accomplish the targets in line with the international standards.
