Electromagnetic compatibility for functional safety

Addressing key topics within the EMC for functional safety sector.

One of the problems peculiar to all electronic technologies is electromagnetic (EM) interference (EMI). All electrical and electronic technologies emit EM disturbances that can interfere with the correct operation of radio-communications or other electronics. Without pre-emptive measures modern electronic technologies are in general more likely to cause such disturbances than those they replace.

All electronic technologies can also suffer from degraded functionality (including complete failure) when exposed to EM disturbances. Without pre-emptive measures modern electronic technologies are in general more likely to be susceptible in this way than those they replace.

The aim of the guidance is to provide management and technical tools that enable the use of electronic technologies in applications where they could have an impact on functional safety – controlling the risks due to EMI for customers and third parties, and thereby reducing financial risks to manufacturers and service providers. The guidance takes into account international work on functional safety as embodied in IEC 61000-1-2.
