This International Standard applies to all electronic equipment for control, regulation,
protection, supply, etc. installed on rail vehicles and associated with
– either the accumulator battery of the vehicle;
– or a low-voltage power supply source with or without a direct connection to the contact
system (transformer, potentiometer device, auxiliary supply) with the exception of electronic
power circuits, which conform to IEC 61287-1.
This standard covers the conditions of operation, design, construction, and testing of electronic
equipment, as well as basic hardware and software requirements considered necessary for
competent, reliable equipment.
Additional requirements in other standards or individual specifications may complement this
standard, if they are justified.
Specific requirements related to practices necessary to assure defined levels of functional
safety are to be determined in accordance with 4.6.3.1 and 4.6.3.2 of IEC 62278 and its
informative Annex A.
Software safety integrity level of 1 or higher shall only be considered when it is shown that a
residual safety risk remains and that it has to be carried by the software driven programmable
electronic system. In such a case (i.e. software safety integrity level 1 or higher), IEC 62279 is
applicable.
For the purposes of this 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.
NOTE Sensors (current, voltage, speed, etc.) and firing unit printed board assemblies for power electronic devices
are covered by this standard. Complete firing units are covered by IEC 61287-1.
