Based on IEC 62847:2016 international standard, the development of rolling stock electric connector standards, classification, main technical characteristics, test methods and its requirements, experimental groups and the number of samples, and environmental severity adaptability were analyzed and surveyed from the perspective of international standards for rolling stock electrical connectors which were widely used in railway fields. By absorbing and referring to international standard for rolling stock electric connectors, the idea about preparing the Chinese national standard for rolling stock electric connectors was proposed, which would promote the formation of Chinese national standard in the field of rolling stock electric connectors.
