CISPR 25 covers a frequency range of 150 kHz to 2.5 GHz and determines the necessary space needed for testing. This standard was developed in response to the variety of radio receivers that can be installed or used in motor vehicles and deals with "radio disturbance characteristics for the protection of receivers used on-board vehicles, boats, and on devices". CISPR 25 is mostly used by vehicle manufacturers to ensure the performance of receivers mounted on the vehicle is top-notch. There are two parts to CISPR 25, full vehicle and components. The full vehicle or system test part uses mounted antennas to sense noise generated by different electronic systems on the same vehicle, where the other part deals with the conducted and radiated measurements of the vehicle's components and modules. The goal of CISPR 25 is to protect the receivers installed in the vehicle from disturbances created by other components or modules within the same vehicle.
*CISPR 25 is not to be used for the protection of electronic control systems from RF (radio frequency) emissions or transient voltage fluctuations. Look for these in ISO standards.
