Including EMC in Risk Assessments
The reliability of electronic technologies (including the software and firmware that runs on them) can become critical, when the consequences of errors, malfunctions or other types of failure include significant financial loss, mission loss, or harm to
people, domestic animals or property (i.e. functional safety). Electromagnetic interference (EMI) can be a cause of unreliability in all electronic technologies, so electromagnetic compatibility(EMC) must be taken into account when the risks caused by malfunctioning electronics are to be controlled. However, levels of reliability or safety risk can be three orders of magnitude beyond what could possibly be demonstrated with any practicable EMC testing regime.
The challenge for engineers is to demonstrate adequate confidence in the reliability of their designs in the operational electromagnetic environment. The solution  is to use well-proven EMC design techniques, plus risk assessment that shows the overall design achieves acceptable risk levels, all verified and validated by a variety of techniques (including EMC testing).
This paper addresses how to apply risk assessment techniques to issues of electromagnetic compatibility (EMC).

EMC Standards is a world-leading resource for all things EMC and EMI related. Our website is packed full of both free and paid-for content, including:
- Online quiz
- Training quiz
- And much more!
Electromagnetic Engineering (EMgineering) is the basis for proven good design practices for signal integrity (SI), power integrity (PI), and the control of EMI emissions and immunity (EMC).
Our aim is to help people learn how to more quickly and cost-effectively design and manufacture electronic equipment (products, systems, installations, etc.) to meet functional (i.e. SI/PI) specifications and conform to EMC standards, directives and other requirements.
Such equipment should benefit from reduced warranty costs and financial risks, whilst improving uptime, competitiveness and profitability.
We also cover basic good electrical safety engineering; and the Risk Management of Electromagnetic Disturbances / EMI, whether for Functional Safety or other types of risk.Join EMC standards TODAY!
