标准范围

CISPR 25:2008包含测量150 kHz至2 500 MHz频率范围内无线电干扰的限制和程序。本标准适用于任何用于车辆、拖车和设备的电子/电气部件。有关频率分配的详细信息，请参阅国际电信联盟（ITU）出版物。这些限制旨在为安装在车辆中的接收器提供保护，使其免受同一车辆中的组件/模块产生的干扰。整车的方法和限制在条款5中，部件/模块的方法和限制在条款6中。只有完整的车辆测试才能用于确定部件相对于车辆极限的兼容性。受保护的接收机类型有，例如，广播接收机（声音和电视）、陆地移动无线电、无线电话、业余无线电、公民无线电、卫星导航（GPS等）。）和蓝牙。就本标准而言，车辆是一种自动推进的机器。车辆包括（但不限于）乘用车、卡车、农用拖拉机和雪地车。附录A为确定本标准是否适用于特定设备提供了指导。本标准中的限值是推荐的，可根据车辆制造商和部件供应商之间的协议进行修改。本标准也适用于在车辆交付后添加并连接到车辆线束或车载电源连接器的部件和设备的制造商和供应商。这第三版取消并取代了2002年出版的第二版。与上一版相比，进行了以下重大更改:-用平均检测器和峰值或准峰值检测器两者添加所需的测量；-增加保护新的模拟和数字无线电服务的方法和限制，覆盖频率范围高达2 500兆赫；-增加一种新的部件测量方法（带状线）作为信息性附件G；-增加CISPR 21的内容作为附件H；CISPR 21现在全部过时；-删除窄带/宽带确定；-删除关于杆状天线特性的附件（CISPR 16-1-4现在涵盖了这一点）；-删除关于屏蔽外壳特性的附件（CISPR 25将在CISPR/D/CISPR/A室验证联合工作组完成其工作后进行修订）。2009年1月更正的内容已纳入本副本。

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.
