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
. It defines the mandatory conditions for design, construction, and testing to ensure that onboard electronics remain reliable in the harsh environments of rail travel. IEC Webstore Core Purpose and Scope iec 60571pdf
Voltage limits: IEC 60571 specifies voltage limits for different types of equipment and circuits, including limits for DC and AC systems.
Protection classes: The standard defines protection classes for electrical equipment, including Class I, Class II, and Class III, based on the level of protection against electrical shock.
Clearance and creepage distances: IEC 60571 specifies clearance and creepage distances for electrical equipment, including distances between live parts, between live parts and earthed metal, and between live parts and other metal parts.
Insulation coordination: The standard requires insulation coordination to ensure that the electrical insulation system can withstand the expected overvoltages.
Improved safety: IEC 60571 helps to ensure that traction and rolling stock are designed and constructed to protect passengers, staff, and maintenance personnel against electrical shock.
Compliance with regulations: The standard helps manufacturers and operators to comply with relevant regulations and laws related to electrical safety.
Reduced risk: IEC 60571 helps to reduce the risk of electrical shock and related accidents, which can lead to injuries, fatalities, and equipment damage.
