  • from EN 954-1:1996 and is supplemented with quality management and reliability aspects, 
  • best suited for less complex systems, 
  • can also be used for other technologies apart from electronics, for example pneumatics or hydraulics,
  • suitable for proof of safety of devices as well as for evaluation of risk reduction of the entire safety function via tables.
