Functional safety

Although the normal procedures developed by the IEC will produce EMC, they are intended to be cost-effective for industry and do not prevent the possibility of electromagnetic interference under worst-case conditions. Consequently in cases where EMI could produce a safety hazard to humans, special procedures need to be investigated.


The basic approach to achieving this functional safety is to evaluate the margins between the expected levels of emissions that create the EM environment and the levels of immunity that equipment possesses. In many cases the most appropriate approach is to raise the immunity level of the equipment to ensure that unsafe conditions do not result during normal operation.
