Overview of techniques and measures related to EMC for Functional Safety

Functional safety is part of the overall safety of a system that depends upon the correct functioning of electrical and/or electronic equipment.  All electronic equipment (hardware and/ or software) is vulnerable to certain electromagnetic disturbances (electromagnetic interference EMI).  The aim of this guide is to provide a non-exhaustive range of techniques and measures that can address the interfering effects of EMI that a safety related system could experience over its complete lifecycle.  When competently selected and applied, a set of such techniques and measures will provide part of the evidence required for functional safety arguments and for compliance with IEC 61508.
