About IET SIL Determination 2014


Industry increasingly relies upon safety systems to maintain and protect operating assets. The concept of Safety Integrity Levels (SIL) is fundamental in ensuring a system satisfactorily performs the required safety functions under all stated conditions, within a defined time period.

Accurately determining the Safety Integrity Level for your system is a topic which generates significant debate within industry across the safety-related community, particularly in relation to standards such as IEC 61508, IEC 61511 and IEC 62061.

Delegates attended a complete day of cross-industry learning current practices, developments and lessons learned on SIL determination, with a particular focus upon the process industries.

The event highlighted the benefits of certain approaches as well as the pitfalls of others and the effects of inappropriate SIL determinations.
