What is BS EN 61508-2:2010?
BS EN 61508-2 applies to any safety related system with at least one electrical, electronic or programmable electronic-based component. It also includes all subsystems and their components within an E/E/PE safety related system, such as sensors, actuators and operator interfaces. The standard demonstrates how overall safety is refined into E/E/PE safety function requirements, as well as safety integrity requirements. BS EN 61508-2 also defines activities that should be applied during the design and manufacturing of these safety related systems.
How does it work?
BS EN 61508-2 first looks at all the required elements to ensure conformance to its specifications, before demonstrating how to manage functional safety. The standard then focuses on E/E/PE system safety lifecycle requirements – including design specifications, system safety validating planning, development and system integration. BS EN 61508-2 concludes with practical guidance on how to conduct a functional safety assessment.
