Tests of electromagnetic compatibility (EMC) play an important role in ensuring the quality and safety of products. Almost every electric or electronic device generates electromagnetic fields and sends or receives electromagnetic signals. As a result, devices can interfere with one another. A cell phone sending a signal to a cell phone antenna may, for instance, cause bursts of radio static or lines to appear on your TV screen. Although this may be annoying, it isn’t harmful. Under certain circumstances, however, electromagnetic interference may pose a serious risk to safety or even health; if, for example, it affects on-board vehicle electronics or medical products (e.g. pacemakers), causing them to malfunction.
To ensure that radio and other electronic equipment neither causes nor is subject to interference, the EU has instituted statutory requirements for electromagnetic compatibility. These requirements are implemented by mandatory CE labeling and EMC Directive 2014/30/EC. Radio equipment has its own legislative regulations in the form of the Radio Equipment Directive (RED) 2014/53/EU, which rates EMC and radio characteristics.
While EMC describes and evaluates the electromagnetic interaction between devices, EMF (electromagnetic fields, EMVU) also evaluates the effect of electromagnetic fields on people and organisms and sets limit values accordingly.
Manufacturers and importers must guarantee that their products comply with the new directives. As an accredited and internationally active EMC laboratory in Hamburg, Hermes Hansecontrol is perfectly placed to assist its customers in this area. As well as testing products ready for series production, we also offer tests for the product development phase – letting you stay on the safe side right from the start.
