1.1 This European Standard specifies procedures and technical requirements for the development of programmable electronic systems for use in railway control and protection applications. It is aimed at use in any area where there are safety implications. These may range from the very critical, such as safety signalling to the non-critical, such as management information systems. These systems may be implemented using dedicated microprocessors, programmable logic controllers, multiprocessor distributed systems, larger scale central processor systems or other architectures. 1.2 This European Standard is applicable exclusively to software and the interaction between software and the system of which it is part. 1.3 Software safety integrity levels above 0 are for use in systems in which the consequences of failure could include loss of life. Economic or environmental considerations, however, may also justify the use of higher software safety integrity levels. 1.4 This European Standard applies to all software used in development and implementation of railway control and protection systems including: – application programming; – operating systems; – support tools; – firmware. Application programming comprises high level programming, low level programming and special purpose programming (for example: Programmable Logic Controller ladder logic). 1.5 The use of standard, commercially available software and tools is also addressed in this European Standard. 1.6 This European Standard also addresses the requirements for systems configured by application data. 1.7 This European Standard is not intended to address commercial issues. These should be addressed as an essential part of any contractual agreement. All the clauses of this European Standard will need careful consideration in any commercial situation. 1.8 This European Standard is not intended to be retrospective. It therefore applies primarily to new developments and only applies in its entirety to existing systems if these are subjected to major modifications. For minor changes, only clause 16 applies.

This standard is applicable to safety-related electronic systems (including sub-systems and equipment) for railway signalling applications. The scope of this standard, and its relationship with other CENELEC standards, are shown in Figure 1. This standard is intended to apply to all safety-related railway signalling systems/sub-system/equipment. However, the hazard analysis and risk assessment processes defined in EN 50126 and this standard are necessary for all railway signalling systems/sub-systems/equipment, in order to identify any safety requirements. If analysis reveals that no safety requirements exist (i.e.: that the situation is non-safety-related), and provided the conclusion is not revised as a consequence of later changes, this safety standard ceases to be applicable. This standard applies to the specification, design, construction, installation, acceptance, operation, maintenance and modification/extension phases of complete signalling systems, and also to individual sub-systems and equipment within the complete system. Annex C includes procedures relating to electronic hardware components. This standard applies to generic sub-systems and equipment (both application-independent and those intended for a particular class of application), and also to systems/sub-systems/equipment for specific applications. This standard is not applicable to existing systems/sub-systems/equipment (i.e. those which had already been accepted prior to the creation of this standard). However, as far as reasonably practicable, this standard should be applied to modifications and extensions to existing systems, sub-systems and equipment. This standard is primarily applicable to systems/sub-systems/equipment which have been specifically designed and manufactured for railway signalling applications. It should also be applied, as far as reasonably practicable, to general-purpose or industrial equipment (e.g.: power supplies, modems, etc.), which is procured for use as part of a safety-related signalling system. As a minimum, evidence shall be provided in such cases to demonstrate either that the equipment is not relied on for safety, or that the equipment can be relied on for those functions which relate to safety. This standard is applicable to the functional safety of railway signalling systems. It is not intended to deal with the occupational health and safety of personnel; this subject is covered by other standards.
