CISPR 12:2025 The limits in this document are designed to provide protection in the frequency range of 30 MHz to 1 000 MHz for off-board receivers. Compliance with this document does not guarantee adequate protection for receivers nearer than 10 m to the vehicle, boat or device. This document applies to the emission of electromagnetic energy that can cause interference to radio reception and which is emitted from:
1) vehicles propelled by an internal combustion engine (ICE), electrical means or both (see 3.1.34);
2) boats propelled by an ICE, electrical means or both (see 3.1.4). Boats are tested in the same manner as vehicles except where they have unique characteristics as explicitly stated in this document;
3) devices equipped with ICE (see 3.1.9). In the case of hybrid devices (e.g. equipped with both ICE and traction batteries), only the ICE mode is included in this document;
4) inboard and outboard boat engines and motors [i.e. equipped with ICE, electric motor (EM), or both], when marketed independently.
See Annex D for a flow chart and a list of examples to help determine the applicability of CISPR 12.
This document does not apply to aircraft, household appliances, medical devices, traction systems (railway engine or locomotive, streetcar or tram and electric trolley bus), vehicle, boat and device off-board chargers or to incomplete vehicles, boats and devices. In the case of a dual-mode trolley bus (e.g. propelled by power from either AC/DC mains or an ICE), the ICE propulsion system is included, but the EM propulsion portion of the vehicle is excluded from this document. In addition, domestic helper robots, such as household cleaning robots, hotel service robots and personal safety robots are also excluded from the scope of this document.
NOTE 1 Other than inboard or outboard boat engines and motors that are marketed independently, this document does not apply to components or incomplete products, such as an ICE, an incomplete vehicle or boat that has not yet been fitted with an ICE or EM, or spare parts. This document only applies to the final product, which is equipped with all applicable parts and components to be able to function as intended.
NOTE 2 Appliances without ICE for typical housekeeping and service functions in the household and similar environment are covered by the requirements of CISPR 14-1[1].
NOTE 3 Protection of receivers used on board the same vehicle as the disturbance source(s) are covered by CISPR 25[2].
This document does not prescribe measurement methods or limits for conducted disturbances, for the charging mode of operation, where the (electric or hybrid) vehicle or boat is connected to power mains, either directly (i.e. plug-in vehicle or boat) or indirectly (i.e. wireless power charging). The user is referred to appropriate IEC and CISPR standards, which define measurement techniques and limits for this condition.
NOTE 4 See IEC 61851-21-1[3] for road vehicles and IEC 61000-6-3[4], IEC 61000-6-4[5] and IEC 61000-6-8[6] for other types of vehicles or boats.
The emission requirements in this document are not applicable to the intentional transmissions from a radio transmitter, as defined by the ITU-R, including its spurious emissions.
Equipment that is covered by other CISPR product and product family emission standards are excluded from the scope of this document, except where they include ICE(s). In the latter case, the equipment complies with this document in all modes of operation where the ICE(s) is(are) active.
NOTE 5 The other CISPR product or product family emission standard can also apply to the equipment for those modes of operation where the ICE(s) is (are) not active. In case the ICE(s) is (are) always in operation, the other CISPR product or product family emission standard can still apply, for verifying the emissions from the other components and circuitry of the equipment.

CISPR 12:2007+A1:2009 The limits in this International Standard are designed to provide protection for broadcast receivers in the frequency range of 30 MHz to 1 000 MHz when used in the residential environment. Compliance with this standard may not provide adequate protection for new types of radio transmissions or receivers used in the residential environment nearer than 10 m to the vehicle, boat or device. This standard applies to the emission of electromagnetic energy which may cause interference to radio reception and which is emitted from
a) vehicles propelled by an internal combustion engine, electrical means or both;
b) boats propelled by an internal combustion engine, electrical means or both. Boats are to be tested in the same manner as vehicles except where they have unique characteristics as explicitly stated in this standard;
c) devices equipped with internal combustion engines.
The following changes were made with respect to the previous edition:
- deletion of narrowband / broadband determination;
- general improvement of wording.
This consolidated version consists of the sixth edition (2007) and its amendment 1 (2009). Therefore, no need to order amendment in addition to this publication.
