At the center of global automotive EMC regulation is the standard. Engineers frequently search for historical and current versions of this document—ranging from the older CISPR 25:2002 to the revised CISPR 25:2021 edition. What is CISPR 25?
Introduces more stringent requirements for the Artificial Mains Networks (AMNs) and Artificial Networks (ANs) used to stabilize test environments. Key Test Methodologies Defined in CISPR 25
standard sets limits and measurement procedures for radio disturbances ranging from 150 kHz to 5,925 MHz

The standard is designed to protect on-board receivers (such as sound systems, televisions, land mobile radios, radiotelephones, amateur, and citizens' radio) from disturbances produced by conducted and radiated emissions arising in a vehicle. It provides:
150 kHz to 5 925 MHz (The 2021 update expanded this significantly).
The standard covers emissions up to 5,925 MHz, accommodating higher-frequency communication systems (5G, modern Wi-Fi). At the center of global automotive EMC regulation
Inclusion of test methods for frequencies above 1 GHz to protect modern 5G, Wi-Fi, and advanced driver-assistance systems (ADAS) radar modules.
CISPR 25:2002 (Edition 2.0) represents an important milestone in the history of automotive electromagnetic compatibility (EMC). It laid the groundwork for many of the testing methods and limits that are still in use today. While this edition has been superseded by more recent versions (2008, 2016, and the currently valid 2021 edition), it remains a valuable reference for understanding legacy vehicle designs, supporting older product lines, and tracing the evolution of EMC requirements in the automotive industry.
While the 2002 standard served the industry well during the transition from analog to digital automotive systems, the reality is that the electromagnetic environment has changed. The explosion of Electric Vehicles (EVs) and Advanced Driver Assistance Systems (ADAS) has made the old limits obsolete. If you'd like, let me know: The standard
The evolution of the standard reflects two decades of technological shifts: Frequency Range: 2002 Edition: Covered disturbances from 150 kHz to 1,000 MHz 2021 Edition: Extended to cover 150 kHz to 5,925 MHz , adding protection for modern bands like 5G, V2X, and Wi-Fi Electric Vehicles (EV): 2002 Edition: Minimal mention of high-voltage systems. 2021 Edition: Includes specific test methods for shielded high-voltage power supply systems EV charging modes Technical Content: 2021 Updates: Introduces technical revisions such as measurement uncertainty annexes and the removal of TEM cell annexes. Refined methods for both conducted emissions (voltage/current probe) and radiated emissions (typically in an absorber-lined shielded enclosure - ALSE).
Pick a number and I’ll produce it.
Pushed the upper limit to nearly 6 GHz to cover modern wireless protocols like 802.11p (V2X) and high-frequency communication. Measurement Uncertainty:
At the center of global automotive EMC compliance is , the international standard developed by the International Special Committee on Radio Interference. This standard defines the limits and methods of measurement of radio disturbance characteristics for the protection of receivers used on board vehicles.
