IEC 55011 applies to industrial, scientific and medical electrical equipment operating in the frequency range 0 Hz to 400 GHz and to domestic and similar appliances designed to generate or use locally radio-frequency energy. It covers emission requirements related to radio-frequency (RF) disturbances in the frequency range of 9 kHz to 400 GHz.
For ISM RF applications in the meaning of the definition found in the ITU Radio Regulations, this document covers emission requirements related to radio-frequency disturbances in the frequency range of 9 kHz to 18 GHz.
ISM equipment, which incorporates radio transmit/receive functions (host equipment with radio functionality), is included in the scope of this document. However, the emission requirements in IEC 55011 are not intended to apply to the intentional transmissions from a radio transmitter as defined by the ITU including their spurious emissions. Requirements for ISM RF lighting equipment and UV irradiators operating at frequencies within the ISM frequency bands defined by the ITU Radio Regulations are contained in IEC 55011.
Robots used for industrial, scientific and medical applications are in the scope of this document.
EXAMPLES: Welding robots, spraying robots, handling robots, processing robots, assembly robots, medical robots, education and experimental robots. A comprehensive list of robots in the scope of this document is given on the IEC EMC zone.
Equipment covered by other CISPR product and product family emission standards are excluded from the scope of this document.
CISPR 11:2024 text has been approved in Europe as EN IEC 55011:2025 without any changes.
