GB/T 24338.5-2009

This standard specifies the electromagnetic compatibility (EMC) requirements for signalling and telecommunications equipment used in railway systems, defining both emission limits to prevent interference and immunity levels to ensure reliable operation in the railway electromagnetic environment. It is applied during the design, testing, and certification of devices such as train control systems, track circuits, and communication networks within railway infrastructure. The standard ensures that these critical safety and communication components function correctly without causing or being affected by electromagnetic disturbances in rail transit applications.
