Abstract：Hydrological testing international standardization plays a fundamental and leading role in promoting international water conservancy project construction,standardizing the operation procedures of testing instruments and equipment,and improving the quality of data collection and analysis.With the intensification of global climate change and the improvement of water resources management needs,the standardization and internationalization of hydrological testing technologies have increasingly gained attention from various countries.This paper systematically combs the development status in the field of hydrological testing technologies,deeply analyzes the progress of standardization work in the hydrological testing field by ISO/TC 113 and CEN/TC 318,and discusses their development goals and corresponding business development strategies from multiple perspectives such as politics,economy,and technology.It points out the constraints on the implementation of business plans from aspects such as human resources and funds,meeting costs and communication,expert drain,and delays in standard-setting cycles,which in turn affect the collaborative development of global hydrological testing technologies.The study suggests that China should accelerate the research on development strategies for the international standardization of hydrological testing,cultivate international standardization compound talents,actively seek efficient and close international partnership,promote friendly exchanges of global hydrological testing technologies,services,and standards,help internationalize China's hydrological standards,boost the development of new quality productive forces in water conservancy.
