Is EMC testing required for products without wireless functionality?

Yes, EMC testing is required for almost all electrical and electronic products, even without wireless functionality. Any device with a clock, microprocessor, or power supply generates electromagnetic energy. Regulations ensure these devices do not cause interference and can withstand external disturbances.

Key Regulatory Requirements

• European Union (EU): Non-wireless products fall under the EMC Directive (2014/30/EU). Compliance is mandatory to legally affix a CE mark.
• United States: The FCC (Part 15) regulates digital devices without intentional radios to ensure unintentional emissions are within legal limits.

The Two Pillars of EMC Testing

1. Emissions: Measures the electromagnetic noise your product emits (both radiated through the air and conducted through power cables) to prevent disruption to other nearby equipment.
2. Immunity: Evaluates your product’s ability to operate correctly without malfunctioning or degrading when exposed to external electromagnetic interference.
