Abstract：In view of the technical bottleneck of impact test in deep cold temperature zone for hydrogen storage materials, the research status of impact test methods in deep cold temperature zone at home and abroad was introduced. The research progress for impact test methods in deep cold temperature zone were described through the following three aspects: the development status of refrigeration technology, the control of temperature zone system, and the impact test technology. It showed that the control of return temperature characteristics of sample by insulation to compensate for the subcooling temperature in the experimental process could effectively solve the accuracy issue in low-temperature impact test in deep cold environments. Finally, the bottlenecks of restricting the development of this technology and the reasons for relatively slow development were analyzed. This study provided references for the standard establishment of impact test in the deep cold environment and the following work in future.
