ISO is a highly authoritative and influential international standards organization. It established a technical committee in the field of rail transportation in 2012, titled “International Organization for Standardization Technical Committee on Railway Applications” (ISO/TC269). In recent years and under the careful organization of the competent department of standardization as well as with the full support of the relevant railway units, CARS, as the domestic technical counterpart of ISO/TC269, has fully participated in and promoted the internationalization of railway standards, striving to shape ISO/TC269 into a significant platform for China’s railway technical standards to enter the international cycle and to open a new chapter of the mutual promotion between international and domestic technology.
