CISPR 25 Ed. 3 (2008-01) is entitled “Vehicles, boats, and internal combustion engines -Limits and methods of measurement for the protection of on-board receivers” CISPR 25:2008 contains limits and procedures for the measurement of radio disturbances in the range of 150 kHz to 2500 MHz. This standard applies to any electronic/electrical component intended for use in vehicles, trailers, and device. Refer to International Telecommunications Union (ITU) for details of frequency allocations. The limits are intended to provide protection for receivers installed in a vehicle from disturbances produced by components/modules in the same vehicle. The method and measurements for a complete vehicle are in Clause 5, and the methods and limits for components/modules are in Clause 6. Only a complete vehicle test can be used to determine the component compatibility with respect to a vehicle’s limit. The receiver types to be protected are, for example, broadcast receivers (sound and television), land mobile radio, radio telephone, amateur radio, citizens band, satellite navigation systems, and Bluetooth. For the purpose of this standard, a vehicle is a machine that is self-propelled. Vehicles include, but are not limited to, cars, trucks, agricultural tractors, and snowmobiles. Annex A provides guidance in determining whether this standard is applicable to particular equipment. The limits in this standard are recommended and are subject to modification as agreed between the vehicle manufacturer and the component supplier. This standard is also intended to be applied by manufacturers and suppliers of components and equipment that are to be added to and connected to the vehicle harness or to an on-board power connector after delivery of the vehicle. This third edition cancels and replaces the second edition published in 2002. Several significant changes have been made in respect to the earlier edition. To view details on these changes, or to purchase the new standard, go to the IEC website. There are SAE standards, standards from each of the major auto makers, and international standards.
