Problems with the EMC requirements in BS7671
New requirements on Electromagnetic Compatibility (EMC) were been added to the 17th Edition [1], andhave been in force since January 2012.
The new Clause 332.1 added some requirements that go beyond those in the EMC Regulations [2] andcould increase that cost of some equipment, and the new Clause 444 does not provide sufficient practicalguidance.
This brief article discusses these issues, and shows where to find well-proven practical guidance.

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
- Webinars
- 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.
