Contemporary FuSa Standards

 

The primary functional safety standards in current use are listed below:

  • IEC EN 61508 Parts 1 to 3 is a core functional safety standard, applied widely to all types of safety critical E/E/PS and to systems with a safety function incorporating E/E/PS. (Safety Integrity Level – SIL)
  • UK Defence Standard 00-56 Issue 2
  • US RTCA DO-178B North American Avionics Software
  • US RTCA DO-254 North American Avionics Hardware
  • EUROCAE ED-12B European Airborne Flight Safety Systems
  • IEC 62304 – Medical Device Software
  • IEC 61513, Nuclear power plants – Instrumentation and control for systems important to safety – General requirements for systems, based on EN 61508
  • IEC 61511-1, Functional safety – Safety instrumented systems for the process industry sector – Part 1: Framework, definitions, system, hardware and software requirements, based on EN 61508
  • IEC 61511-2, Functional safety – Safety instrumented systems for the process industry sector – Part 2: Guidelines for the application of IEC 61511-1, based on EN 61508
  • IEC 61511-3, Functional safety – Safety instrumented systems for the process industry sector – Part 3: Guidance for the determination of the required safety integrity levels, based on EN 61508
  • IEC 62061, Safety of machinery – Functional safety of safety-related electrical, electronic and programmable electronic control systems, based on EN 61508
  • ISO 13849-1, -2 Safety of machinery – Safety-related parts of control systems. Non-technology dependent standard for control system safety of machinery. (Performance Levels – PL)
  • EN 50126, Railway Industry Specific – RAMS review of Operations, System and Maintenance conditions for project equipment
  • EN 50128, Railway Industry Specific – Software (Communications, Signaling & Processing systems) safety review
  • EN 50129, Railway Industry Specific – System Safety in Electronic Systems
  • EN 50495, Safety devices required for the safe functioning of equipment with respect to explosion risks
  • NASA Safety Critical Guidelines
  • ISO 25119 – Tractors and Machinery for Agriculture and Forestry — Safety-Related Parts of Control Systems
  • ISO 26262 – Road Vehicles Functional Safety

The standard ISO 26262 particularly addresses the automotive development cycle. It is a multi-part standard defining requirements and providing guidelines for achieving functional safety in E/E systems installed in series production passenger cars. The standard ISO 26262 is considered a best practice framework for achieving automotive functional safety.
