BS EN 61508-5:2010 Functional safety of electrical/electronic/ programmable electronic safety related systems. Examples of methods for the determination of safety integrity levels
BS EN 61508-5 provides information on:
- The underlying concepts of risk and the relationship of risk to safety integrity
- A number of methods that will enable the safety integrity levels for the E/E/PE safety-related systems, other technology safety-related systems and external risk reduction facilities to be determined.
The method selected will depend upon the application sector and the specific circumstances under consideration. Annexes B, C, D and E illustrate quantitative and qualitative approaches and have been simplified in order to illustrate the underlying principles.
