IEC 61000-4-39 is an international specifies specifies immunity requirements for electrical and electronic equipment when it is exposed to radiated electromagnetic energy from RF transmitters used in close proximity. It establishes test levels and the required test procedures. The applicable frequency range is 9 kHz to 6 GHz. Fixed-installation equipment being exposed to portable transmitting devices, mobile equipment exposed to fixed transmitting devices and mobile equipment exposed to other mobile transmitting devices are considered. The object of this document is to establish a common reference for evaluating the immunity requirements of electrical and electronic equipment that is exposed to radiated, RF electromagnetic fields from sources at close distances.

It is understood that this part of IEC 61000 does not replace general immunity requirements of
electrical and electronic equipment to radiated electromagnetic energy as given in IEC 61000-4-3 and other parts of IEC 61000 and that it is only applicable if an equipment or system is exposed to disturbance sources in close proximity. In the context of this document, “close proximity” generally refers to a separation distance between the source and victim equipment of less than or equal to 200 mm for frequencies greater than 26 MHz and 500 mm for frequencies lower than 26 MHz.

As a primary focus of this standards is related to magnetic field disturbance sources in the frequency range 9 kHz to 26 MHz, common frequencies for RFID readers, it has been added to the most current version of the EN IEC 60601-1-2: 2020 Edition 4.1 basic EMC requirements for medical devices, and  in some cases replaces the AIM 7351731 standard which has similar requirements.
