EN IEC 55015 specifies the limits and measurement methods for radio disturbance characteristics of electrical lighting and similar equipment. It covers the frequency range from 9 kHz to 400 GHz, detailing the standards for emissions that may cause interference to radio and telecommunications equipment. The standard applies to various lighting devices, including lamps, luminaires, and auxiliary devices such as ballasts and transformers. It ensures that these devices do not produce harmful electromagnetic disturbances, ensuring their compliance with electromagnetic compatibility (EMC) requirements for both residential and industrial environments.
