Embedded systems are becoming increasingly important in system technologies such as traffic management and train protection as well as on-board systems. In this industry the costs of software failure can be huge, resulting in recalls, brand reputation and even loss of life. Together with adoption of international standards this is driving industry leaders to improve safety-critical software quality.
Railways standards
The railways sector has rigorous safety standards. CENELEC (the European Committee for Electrotechnical Standardization) produces the main standard for the railway industry, EN 50128. The international published version of the CENELEC EN 50128 standard is IEC 62279. The content of both publications is identical.
The EN 50128 standard outlines procedures and technical requirements for the development of programmable electronic systems for use in railway applications. It is applicable to all cases where safety is, or may be, a consideration. The EN 50128 standard also requires use of coding standards such as MISRA and CERT.
