Officially titled "Electronic equipment used on rail vehicles," IEC 60571 is the global benchmark for the design, testing, and performance of electronic devices installed on trains. Published by the International Electrotechnical Commission (IEC), it provides the "rules of the road" for manufacturers.
Whether it's a locomotive control unit or a passenger Wi-Fi router, if it has a circuit board and goes on a train, it likely needs to meet the rigorous demands of this standard.
IEC 60571 applies to all electronic equipment that is fixed to railway rolling stock. This includes: Iec 60571.pdf
The standard covers equipment for DC and AC supplied railways, from low-power electronics up to high-power auxiliary converters.
The standard specifies clearances, creepage distances, and dielectric tests based on the nominal voltage and overvoltage category (typically OV3 for rolling stock). For example: The standard covers equipment for DC and AC
IEC 60571 does not stand alone. It references and works alongside several other important standards:
In many projects, compliance with IEC 60571 is required alongside EN 50155 (electronic equipment for rolling stock) – indeed, IEC 60571 and EN 50155 are technically aligned for most requirements, but EN 50155 is more common in European procurement. IEC 60571 is often used globally as a baseline. In many projects, compliance with IEC 60571 is

Compare your existing electronic unit (e.g., a new display screen or a controller) against the 2012 edition. Focus on:
The standard requires a Test Report and Compliance Declaration. Keep your Iec 60571.pdf handy for referencing clause numbers in your compliance matrix.
