DS/EN 55012/A1:2009 车辆、船只和内燃机 无线电干扰特性 保护非车载接收器的限值和测量方法

Item c) to read:”c) devices equipped with internal combustion engines or traction batteries (see 3.3).”3rd paragraph to read:“This standard does not apply to aircraft, household appliances, traction systems (railway,tramway and electric trolley bus), or to incomplete vehicles. In the case of a dual-mode trolleybus (e.g. propelled by power from either a.c./d.c. mains or an internal combustion engine), theinternal combustion propulsion system shall be included, but the a.c./d.c. mains portion of thevehicle propulsion system shall be excluded from this standard.”

BS EN 55012:2007 车辆、船舶和内燃机.无线电干扰特性.离船接收机保护用测量的限值和方法

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. NOTE 1 Experience has shown that compliance with this standard may provide satisfactory protection for receivers of other types of transmissions when used in the residential environment, including radio transmissions in frequency ranges other than that specified. 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 (see 3.3). See Annex G for a flow chart to help 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. NOTE 2 Protection of receivers used on board the same vehicle as the disturbance source(s) are covered by CISPR 25. 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 IEC and CISPR standards which define measurement techniques and limits for this condition. Annex H lists work being considered for future revisions.
