WG 4.5 Functional Safety

Focus

The "Functional Safety" working group addresses issues including the following topics in the context of its experience exchange, its concept developments, formulation of requirements to be met by automation solutions and its involvement in national and international standardisation:

  • Prior use devices (NE 130)
  • Electromechanical devices in Safety Instrumented Systems (NE142)
  • Sharing SIS devices for operational use
  • Useful lifetime of SIS devices
  • Explosion protection and functional safety
  • Machine safety and functional safety
  • IT security and functional safety
  • Human factors and functional safety
  • Review IEC 61511
  • Review VDI/VDE 2180

Advantages

  • Avoidance of extensive and unnecessary expense by active collaboration in all standardisation institutions
  • Development of system solutions
  • Harmonisation in national and international standardisation institutions
