RED Certification (Radio Equipment Directive) is a directive established by the European Union for radio equipment, aiming to ensure that radio communication devices sold in the EU market comply with health, safety, and environmental protection standards. The RED certification applies to all radio devices, including mobile phones, routers, wireless headsets, and more, requiring the devices to meet electromagnetic compatibility (EMC) and radiofrequency radiation standards to minimize potential harm to health and other devices. Products with RED certification demonstrate compliance with EU radio equipment regulations, allowing them to be freely sold within the European Economic Area (EEA). The certification process includes testing the device’s use of radio frequency spectrum, electromagnetic interference (EMI), and safety aspects. RED certification helps manufacturers ensure their products are compliant, reducing the risk of market bans or penalties due to non-compliance with EU regulations. Several communication modules from Tuya’s WBR series have passed the EU Commission’s RED cybersecurity certification and received test reports and RED cybersecurity NB certificates issued by TÜV SÜD, a German certification organization, based on the EU Commission’s EN 18031 series standards.
