Functional safety standards
IEC 61508 is the international standard for safety related systems associated with electrical, electronic and software-based safety-related systems. The reliability of these systems is determined by the Safety Integrity Level (SIL) of the safety function they perform. In practice, functional safety methods also extend to the non-electrical, electronic and programmable systems (E/E/PS) parts of the system that the E/E/PS actuates, controls or monitors.
Increasingly, certification to IEC 61508, IEC 61511 and other related standards such as IEC 62061 or ISO 13849 is being encouraged by regulatory authorities and specified by end-users as a way of to help minimize risk and demonstrate best practices.
