International Standards and Conformity Assessment for all electrical, electronic and related technologies



Reference EN 55025:2008
Title Vehicles, boats and internal combustion engines - Radio disturbance characteristics - Limits and methods of measurement for the protection of on-board receivers
Project Number 21176
Abstract/Scope CISPR 25:2008 contains limits and procedures for the measurement of radio disturbances in the frequency range of 150 kHz to 2 500 MHz. The standard applies to any electronic/electrical component intended for use in vehicles, trailers and devices. Refer to International Telecommunications Union (ITU) publications 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 limits 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, citizens' radio, Satellite Navigation (GPS, etc.) and Bluetooth. For the purpose of this standard, a vehicle is a machine, which is self-propelled. Vehicles include (but are not limited to) passenger 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 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 which are to be added 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. The following significant changes were made with respect to the previous edition: - addition of required measurements with both an average detector and a peak or quasi-peak detector; - addition of methods and limits for the protection of new analogue and digital radio services, which cover the frequency range up to 2 500 MHz; - addition of a new measurement method for components (stripline) as an informative Annex G; - addition of the contents of CISPR 21 as Annex H; CISPR 21 in its entirety now becomes obsolete; - deletion of narrowband / broadband determination; - deletion of the Annex on rod antenna characterisation (this is now covered by CISPR 16-1-4); - deletion of the Annex on characterisation of shielded enclosure (CISPR 25 will be amended when the CISPR/D / CISPR/A Joint Task Force on chamber validation finishes its work). The contents of the corrigendum of January 2009 have been included in this copy.
