EMC engineering

Changing enclosures, PCB layouts, component sources, or software doesn't mean the schematic changed—but it may mean your EMC certification did. This installment of Standards Practice breaks down which hardware modifications trigger the need for retesting, and why skipping it can be a costly mistake.

Choosing the right antenna can make or break your compliance testing results. This practical guide walks engineers through the essentials—frequency range, polarization, gain, and directivity—while decoding which antenna types deliver the most accurate, reliable measurements in real‑world EMC and RF test environments.

Decades of global collaboration have shaped today’s automotive EMC standards. From CISPR 25 and ISO 11452 to UNECE R10, this piece reveals how harmonization, travel, technical debate, and human connection have created the consistent, repeatable EMC frameworks the industry depends on.
