About the session
This presentation will summarize the proven in use evidence requirements in IEC 61508 Part 2, outline the key additional requirements for software in TS 61508-3- 1, and describe some of the practical difficulties which might be encountered in providing a convincing proven-in-use case.
Industry increasingly relies upon safety systems to maintain and protect operating assets.
Systems comprised of electrical or electronic elements have been widely used to perform safety functions in most application sectors.
The oil and gas industry, nuclear plants, and transport sector, to name but a few, all rely heavily on functional safety.
The functional safety compliance requirements of IEC 61508 and IEC 61511 and other standards covering safety-related systems are increasingly being specified in procurement specifications in a wide range of sectors and increasingly diverse applications.
The standards are also being used not just for functional safety but also for asset protection.
Allied to the need to have adequate levels of functional safety to meet safety / environment risks is the need to ensure that safety-related systems are properly protected against cyber-attacks. The latter is becoming increasingly important, hence a Workshop on Cyber Security for Safety Critical Systems this year.
