GB 14023-2011 Vehicles,boats and internal combustion engine—Radio disturbance characteristics—Limits and methods of measurement for the protection of off-board receivers
Vehicles,boats and internal combustion engine—Radio disturbance characteristics—Limits and methods of measurement for the protection of off-board receivers
The limits in this 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 (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 or traction batteries (see 3.3).
See Appendix G for a flow chart to help determine the applicability of this standard.
This standard does not apply to aircrafts, household appliances, 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 shall be included, but the a.c./d.c. mains portion of the vehicle propulsion system shall be excluded from this standard.
Note 2: Protection of receivers used on board the same vehicle as the disturbance source(s) are covered by GB/T 18655.
The measurement of electromagnetic disturbances while the vehicle is connected to power mains for charging is not covered in this standard. The user is referred to appropriate national standards which define measurement techniques and limits for this condition.
