Scope of this Standard

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 transmission or receivers used in the residential environment nearer than 10m 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 or both (see 3.1); b) boats propelled by an internal combustion engine, electrical means or both (see 3.2). 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 (see 3.3). See Annex G for a flow chart to determine the applicability of CISPR 12. This standard does not apply to aircraft, traction systems (railway, tramway and electric trolley bus), or to incomplete vehicles. In the case of a dual-mode trolley bus (e.g. propelled by power from either a.c/d.c mains or an internal combustion engine), the internal combustion propulsion system must be included, but the a.c/d.c mains portion of the vehicle propulsion system is excluded from this standard. The measurement of electromagnetic disturbances while the vehicle is connected to power mains for charging is not covered in this standard.
