This IEEE Standard provides guidance on the assessment and application of techniques and measures that can help reduce the risks associated with the interfering effects of electromagnetic disturbances on digital electronic systems, especially safety- or mission-related systems. When competently selected and applied, a set of such techniques and measures can provide the part of the evidence relevant to EMI required for justifying functional safety decisions and for compliance with functional safety standards (including all applicable parts of IEC 61508 Ed.2:2010 or functional safety standards that are based on IEC61508). They can also provide part of the evidence relevant to EMI for medical/healthcare systems for which risks are managed in accordance with ISO14971:2007. This standard supports the adoption of adequate electromagnetic resilience engineering practices throughout the functional safety lifecycle by offering further guidance and practical advice on the application of risk management activities, including the techniques and measures set out in IEC 61000-1-2:2016. While it is primarily intended to be used by those who have responsibilities for functional safety, the methodologies, techniques, and measures it describes can also be used for the reduction of other kinds of risks in any systems that employ electronic technology, such as security risks and non–safety- related risks (for example, risks to the operation of commercial IT systems).
