CISPR 25:2002 is a standard that specifies the EMC requirements for electrical and electronic components and modules used in vehicles. The standard covers the frequency range from 150 kHz to 2.5 GHz and sets limits for electromagnetic emissions (EME) and immunity to electromagnetic disturbances. The standard applies to vehicles with a maximum operating voltage of 1000 V DC and a maximum operating current of 100 A. In the quiet, copper-lined world of an ,
Many legacy vehicles and long-term manufacturing contracts are still tied to this 2002 standard. If a supplier is manufacturing a replacement part for a car designed in 2008, they may be contractually required to test against the 2002 limits, not the modern ones.

The latest release addresses the "connected car" era. Key updates include: Frequency Expansion:
Must use an RF-shielded room to ensure ambient noise is at least 6 dB lower than the lowest measurement limit. Artificial Network (AN/LISN):
However, the 2002 version had imperfections. It struggled with reproducibility. If Lab A tested a part and Lab B tested the same part, they might get different results due to subtle variations in the setup—the ground plane, the harness length, or the table material. This lack of correlation is the nightmare of the EMC engineer.
