BS EN 61508-3:2010

IEC is a basic functional safety standard applicable to all kinds of industry. Each has defined their own scheme based upon IEC and other functional safety standards. It defines functional safety as: A set of guidelines for the development of vehicle based software was published in November A probabilistic failure approach to account for 6108-3 safety impact of device failures. Requirement for SC are presented in a series of tables in Part 2 and Part 3.

What is IEC 61508?

Retrieved from ” https: It is intended to cover the development of software for railway control and protection including communications, signaling and processing systems.

Those requirements are listed in a document called the certification scheme. Certification is third party attestation that a product, process, or system meets all requirements of the certification program. This includes operating systems, computer software, software in communication networks, interfaces, support tools and applications.

IEC provides requirements and recommendations for the instrumentation and control for systems important to safety of nuclear power plants. Errors introduced anywhere from the initial concept, risk analysis, specification, design, installation, maintenance and through to disposal could undermine even the most reliable protection. The probability metric used in step 3 above depends 61508- whether the functional component will be exposed to high or low demand:.
