This European Standard applies to all electronic equipment for control, regulation, protection, diagnostic, energy supply, etc. installed on rail vehicles.<\/p>\n

For the purpose of this European Standard, electronic equipment is defined as equipment mainly composed of semiconductor devices and recognized associated components. These components will mainly be mounted on printed boards.<\/p>\n

Sensors (current, voltage, speed, etc.) and Semiconductor drive unit (SDU) for power electronic devices are covered by this standard. Complete Semiconductor drive unit (SDU) and power converters are covered by<\/p>\n

This European Standard covers the conditions of operation, design requirements, documentation, and testing of electronic equipment, as well as basic hardware and software requirements considered necessary for compliant and reliable equipment.<\/p>\n

Specific requirements related to practices necessary to ensure defined levels of functional safety will be determined in accordance with relevant railway safety standards.<\/p>\n

The software requirements for on board railway equipment are specified by EN 50657<\/span> <\/span>.<\/p>\n
