GB/T 18655-2018 Vehicles,boats and internal combustion engines—Radio disturbance characteristics—Limits and methods of measurement for the protection of on-board receivers

Scope

This standard specifies the radio interference limits and test methods within the frequency range of 150 kHz to 2,500 MHz. This standard applies to any electronic/electrical components used in vehicles, trailers, and devices. The details of the frequency distribution in this standard refer to International Telecommunication Union (ITU) publications and actual applications in China. The limits in this standard are used to protect vehicle receivers from interference generated by components/modules in the same vehicle. Chapter 5 provides methods and limits for measuring entire vehicles (whether connected to the power grid for charging or not), and Chapter 6 provides methods and limits for measuring components/modules. Only vehicle tests conducted according to vehicle limits can be used for the final evaluation of component compatibility. The types of protected receivers include: broadcast receivers (audio and television), terrestrial mobile communications, wireless telephones, amateur and civilian radio equipment, satellite navigation systems (Beidou, GPS, etc.), WiFi, and Bluetooth devices. The vehicles in this standard are devices that can drive themselves by internal combustion engines, electricity, or a combination of both. Vehicles include (but are not limited to) passenger cars, trucks, agricultural tractors, and snowmobiles. Refer to the flowchart in Appendix A to determine whether a device or equipment is suitable for this standard. This standard does not include content on protecting electronic control systems from radio frequency (RF) emissions, transient or pulsed voltage fluctuations. These contents are included in other standardization committee publications. The limits in this standard are recommended values and can be changed upon agreement between vehicle manufacturers and component suppliers. This standard also applies to components and devices added and connected to vehicle wiring harnesses or on-board power connectors after the vehicle is delivered f
