Abstract: As one of the important carriers of global energy revolution and low-carbon development,hydrogen is an important component of China’s future national energy system. Recently,a new method to improve the reproducibility of fire test is proposed in the Global Technical Regulation No.13 for hydrogen and fuel-cell vehicles（UN GTR 13）phase 2,which will have a significant impact on the development of hydrogen fuel cell vehicles in China. This paper analyses the problem on reproducibility of fire test,systematically studies the main contents,characteristics and technical reasons of the new method for fire test,points out the challenges of standard setting,test facilities and technical research,and proposes some suggestions.
