Abstract

       CISPR 25:2016 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 (whether connected to the power mains for charging purposes or not) 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.), Wi-Fi and Bluetooth. For the purpose of this standard, a vehicle is a machine, which is self-propelled by an internal combustion engine, electric means, or both. 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. This fourth edition cancels and replaces the third edition published in 2008. This edition constitutes a technical revision.

       This edition includes the following significant technical changes with respect to the previous edition:
       - inclusion of charging mode for electric vehicles (EV) and plug-in electric vehicles (PHEV)
        括電動汽車EV 和插電式混合動力汽車PHEV
       - the methods for chamber validation have been included
        暗室校驗方法
       -methods for shielded power supply systems for high voltages for electric and hybrid electric vehicles have been included,
       動汽車和混合動力電動汽車的高壓屏蔽電源測試方法
       - overall improvement.
