IEC 60571:2012 sets the international standard for electronic equipment on railway rolling stock, covering design, manufacturing, and testing for environmental and electrical reliability. It outlines crucial performance requirements for rail systems, including temperature ranges, voltage fluctuations, and Electromagnetic Compatibility (EMC), aligned closely with the EN 50155 standard. The full standard and its technical specifications can be obtained at IEC Webstore. IEC 60571:2012 - iTeh Standards
The IEC 60571 standard is the international benchmark for the design, manufacture, and testing of electronic equipment used on railway rolling stock. Whether it is a high-speed train or a local metro, any electronic system—from passenger information displays to engine control units—must meet the rigorous criteria outlined in this document to ensure safety and reliability in harsh railway environments. What is IEC 60571? The 3rd edition aligns with IEC 62278 (RAM)
The standard, titled "Railway applications - Rolling stock - Electronic equipment," covers the total lifecycle of electronic hardware and software. It provides a framework for equipment to withstand the unique stresses of rail travel, including extreme temperature fluctuations, high humidity, mechanical shocks, and electromagnetic interference.
The current version, IEC 60571:2012, replaces older iterations to better align with modern technological advances in digital electronics. Key Areas Covered in IEC 60571
The document is divided into several critical sections that engineers and manufacturers must follow:
Operating Conditions: Specifies the ambient temperature classes, humidity levels, and altitude requirements equipment must endure.
Design & Construction: Guidelines on component selection, PCB (Printed Circuit Board) design, and protective coatings (conformal coating) to prevent corrosion.
Reliability & Maintainability: Requirements for the predicted "Mean Time Between Failures" (MTBF) and how easily the equipment can be repaired.
Testing Procedures: A comprehensive list of mandatory and optional tests, such as:
Vibration and Shock Tests: Ensuring the unit doesn't shake apart on the tracks.
Dry Heat and Low-Temperature Tests: Simulating extreme seasonal climates.
Electromagnetic Compatibility (EMC): Making sure the electronics don't interfere with the train's signaling or radio systems. IEC 60571 vs. EN 50155
In the railway industry, you will often see IEC 60571 mentioned alongside EN 50155. While they are very similar, EN 50155 is the European regional standard, whereas IEC 60571 is the global international standard. Most modern certifications are harmonized, meaning equipment that passes one will typically meet the requirements of the other. How to Access the IEC 60571 PDF

IEC 60571 is the international standard for electronic equipment used on rail vehicles. It defines the requirements for the design, construction, and testing of electronic control, regulation, protection, and supply equipment installed on rolling stock. The latest edition is IEC 60571:2012. Key Content & Scope
Application: Covers electronic equipment, excluding power circuits, powered by vehicle batteries or low-voltage supplies.
Conditions & Design: Defines requirements for environmental conditions (temperature, shock, vibration) and construction, including software and reliability.
Testing: Specifies procedures to ensure performance under harsh conditions. Comparison with EN 50155
EN 50155 serves as the equivalent European standard, often providing more specific details on operational temperature ranges.
IEC 60571 references other standards (like parts of the IEC 61000 series) to ensure equipment is immune to external interference and does not emit excessive noise that could disrupt signaling systems.
The standard outlines specific temperature classes. For example, an device might be tested to operate continuously at +55°C or +70°C, and survive storage temperatures as low as -40°C. It also tests for humidity, salt mist (for coastal operations), and dust ingress.
IEC 60571 is an international standard developed by the International Electrotechnical Commission (IEC). Its full title is “Electronic equipment used on rail vehicles.”
Simply put, it defines the rules and test methods for electronic devices installed on rolling stock (trains, trams, locomotives, and wagons). The standard acts as a comprehensive checklist to ensure that electronic hardware can survive the unique and harsh environment of railway operations.
While modern railway electronics are increasingly governed by EN 50155 (the European standard), IEC 60571 remains a foundational global reference, often harmonized with or serving as the basis for regional regulations.
