This standard applies to industrial, scientific, and medical (ISM) electrical equipment operating in the frequency range of 0 Hz to 400 GHz, as well as domestic and similar appliances designed to generate and/or use radio-frequency energy locally. It covers emission requirements related to radio-frequency (RF) disturbances from 9 kHz to 400 GHz, with measurements needed only in frequency ranges where limits are specified in Clause 6. For ISM RF applications as defined by the ITU Radio Regulations, emission requirements are covered from 9 kHz to 18 GHz. It also includes requirements for ISM RF lighting equipment and UV irradiators operating within ISM frequency bands. Equipment covered by other CISPR products and product family emission standards are excluded.

This sixth edition cancels and replaces the fifth edition (2009) and its Amendment 1 (2010), constituting a technical revision. It introduces and permits type testing on components of power electronic equipment, systems, and installations, with emission limits now applying to low voltage (LV) a.c. and d.c. power ports regardless of power transmission direction. Several limits have been adapted to practical test conditions and now apply to power electronic ISM RF equipment used for wireless power transfer (WPT) for instant power supply and charging purposes. Limits in the range of 1 GHz to 18 GHz now apply to both continuous wave (CW) and fluctuating disturbances in a uniform, technology-neutral manner. Two alternative methods of measurement, the traditional log-AV method, and the new APD method, are available for these measurements. This standard holds the status of a Product Family EMC standard in accordance with IEC Guide 107 (2014).
