: Braking control units, door synchronization hardware, and driving data recording systems.

The two standards are considered in many applications, but they are not identical. A key differentiator lies in their scope: EN 50155 explicitly references IEC 60571 for testing , while IEC 60571 references EN 50155 for mechanical shock and vibration requirements. They are designed to work together, not in competition. However, when they overlap, differences exist:

IEC 60571 is a critical standard for the railway industry, ensuring that electrical equipment on railway rolling stock is safe, reliable, and compatible with the railway infrastructure. The standard has undergone several revisions, and its current edition, IEC 60571:2015, provides the most up-to-date requirements for electrical equipment used on railway rolling stock. As the railway industry continues to evolve, IEC 60571 will remain an essential standard for ensuring the safety, reliability, and performance of electrical equipment on railway rolling stock.

IEC 60571, "Railway applications - Electronic equipment used on rolling stock," establishes essential design, construction, and testing standards for on-vehicle electronics, paralleling the EN 50155 European standard. The standard mandates rigorous environmental, power supply, and reliability testing for components used in railway environments.
