CISPR PAS 38:2025(Main)

Industrial, scientific and medical equipment – Radio-frequency disturbance characteristics – Requirements for radio beam wireless power transfer (RB-WPT) equipment

CISPR PAS 38:2025, which is a Publicly Available Specification, applies to radio beam wireless power transfer (RB‑WPT) as industrial, scientific, and medical equipment operating in the frequency range of 0 Hz to 400 GHz and designed to operate up to a distance of 10 m. This document covers emission requirements related to radio-frequency disturbances in the frequency range of 150 kHz to 18 GHz. Radio beam wireless power transfer devices are in the scope of this document only if they are not classified as radio apparatus.
NOTE 1 Wireless power transfer devices that use a modulated signal to transmit both power and information are classified as radio apparatus in most countries. While radio beam wireless power transfer devices are included in the scope of this document, these can be classified as radio apparatus in some countries, even if the transmitted signal is continuous wave, with no modulation. The user is advised to verify the applicable national radio regulations before applying this document for these types of devices, especially regarding to limits applicable within the ISM bands wherein this document allows unrestricted radiation.
NOTE 2 Radio beam wireless power transfer devices can generate significant electromagnetic energy. While this document does not include requirements for radio-frequency (RF) exposure, the user is warned to take appropriate measures to ensure testing personnel and other bystanders are not subjected to harmful levels of RF exposure from the product under test.
This PAS adopts the requirements from CISPR 11 and provides important clarifications on the application of CISPR 11 for RB-WPT.

CISPR 11:2024(Main)

Industrial, scientific and medical equipment - Radio-frequency disturbance characteristics - Limits and methods of measurement

CISPR 11:2024 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 and/or use locally radio-frequency energy. This document 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 (2020) (see Definition 3.1.18), 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, see Annex F. However, the emission requirements in this document are not intended to be applicable to the intentional transmissions from a radio transmitter as defined by the ITU including their spurious emissions.
NOTE 1 This exclusion only applies to emissions from the intentional radio transmitter. However, combination emissions, for example emissions resulting from intermodulation between the radio and the non-radio subassemblies of the ISM equipment, are not subject to this exclusion.
NOTE 2 Emission requirements for induction cooking appliances are specified in CISPR 14-1.
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 this document.
Robots used for industrial, scientific and medical applications are in the scope of this document.
EXAMPLE 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.
NOTE 3 Flying robots, domestic helper robots, toy robots and entertainment robots are examples of robots in the scope of other CISPR standards.
Equipment covered by other CISPR product and product family emission standards are excluded from the scope of this document.
This seventh edition cancels and replaces the sixth edition published in 2015, Amendment 1:2016 and Amendment 2:2019. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
a) introduction of limits for radiated disturbances in the frequency range above 1 GHz for group 1 equipment in line with the requirements given in the generic emission standards;
b) introduction of limits for conducted disturbances on the wired network port in line with the requirements given in the generic emission standards;
c) introduction of requirements for equipment which incorporates radio transmit/receive functions;
d) introduction of definitions for various types of robots;
e) consideration of some particular conditions when measuring robots, such as measurement setups and operating modes of robots.

CISPR 11:2015(Main)

Industrial, scientific and medical equipment - Radio-frequency disturbance characteristics - Limits and methods of measurement

CISPR 11:2015 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 and/or use locally radio-frequency energy. This standard covers emission requirements related to radio-frequency (RF) disturbances in the frequency range of 9 kHz to 400 GHz. Measurements need only be performed in frequency ranges where limits are specified in Clause 6. For ISM RF applications in the meaning of the definition found in the ITU Radio Regulations (see Definition 3.13), this standard covers emission requirements related to radio-frequency disturbances in the frequency range of 9 kHz to 18 GHz. 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 this standard. Equipment covered by other CISPR product and product family emission standards are excluded from the scope of this standard. This sixth edition cancels and replaces the fifth edition published in 2009 and its Amendment 1 published in 2010. It constitutes a technical revision. It introduces and permits type testing on components of power electronic equipment, systems and installations. Its emission limits apply now to low voltage (LV) a.c. and d.c. power ports, irrespective of the direction of power transmission. Several limits were adapted to the practical test conditions found at test sites. They are also applicable now to power electronic ISM RF equipment used for wireless power transfer (WPT), for instant power supply and charging purposes. The limits in the range 1 GHz to 18 GHz apply now to CW-type disturbances and to fluctuating disturbances in a similar, uniform and technology-neutral way. For these measurements, two alternative methods of measurement are available, the traditional log-AV method and the new APD method. It has the status of a Product Family EMC standard in accordance with IEC Guide 107, Electromagnetic compatibility - Guide to the drafting of electromagnetic compatibility publications (2014).

For ISM RF applications in the meaning of the definition found in the ITU Radio Regulations (see Definition 3.1), this standard covers emission requirements related to radio-frequency disturbances in the frequency range of 9 kHz to 18 GHz. Requirements for ISM RF lighting apparatus and UV irradiators operating at frequencies within the ISM frequency bands defined by the ITU Radio Regulations are contained in this standard. Equipment covered by other CISPR product and product family emission standards are excluded from the scope of this standard. This fifth edition of CISPR 11 cancels and replaces the fourth edition published in 2003, its Amendment 1 (2004) and Amendment 2 (2006). It constitutes a technical revision. This fifth edition of CISPR 11 got a more transparent structure, introduces another set of particular limits for conducted and radiated disturbances of 'heavy duty' general purpose equipment of class A group 1 with a rated input power in excess of 20 kVA, in accordance with the needs of the industries and refers to the full approach in respect of the measurement instrumentation uncertainty specified in CISPR 16 4 4. Furthermore, any kind of 'legal statements' were removed from the normative main body of this International Standard.
