Meaning
European harmonized standards establish the testing procedures and exposure limits for electromagnetic fields generated by household and similar electrical appliances. Under en 50684, manufacturers evaluate the magnetic and electric field strengths to ensure user safety during operation. The framework applies to devices used in residential environments.
Technical Requirement
Compliance dictates that the emission levels remain below the reference levels defined for public exposure. The en 50684 standard uses a specific set of weighting filters to model the human nervous system response to low-frequency fields. These filters shape the measured signals to reflect the biological sensitivity of the human body.
Evaluation Protocol
Laboratory technicians position the appliance at a standardized distance from the field probe to record the emissions. During tests under en 50684, the device must run in the operating mode that produces the highest field levels. The measurement covers both the static operating state and the transient switching events of the appliance.
Product Certification
The test report represents the documentation needed to apply the CE mark to the finished product. To satisfy en 50684, the technical file must include the calculated exposure ratios and the details of the measurement setup. This documentation must be kept by the manufacturer for inspection by national market surveillance authorities.
If the appliance fails to meet these criteria, it cannot be legally sold or distributed within the European Economic Area.
