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.

- test methods for shielded power supply systems for high voltages for electric and hybrid electric vehicles have been included, cispr 25 2002 pdf 2021 download

The keyword "" refers to two significant milestones in automotive Electromagnetic Compatibility (EMC) standards. CISPR 25, officially titled "Radio disturbance characteristics for the protection of receivers used on board vehicles, boats, and on devices," is the global benchmark for ensuring electronic components don't interfere with a vehicle's own radio and communication systems. Evolution from 2002 to 2021 Evolution of the Standard The evolution of the

is the primary international standard for protecting on-board radio receivers in vehicles, boats, and internal combustion engines from electromagnetic disturbances . While the 2002 version (Second Edition) established the foundational framework, it has since been superseded by more modern editions to keep pace with automotive technology, specifically the 2021 release . Evolution of the Standard and on devices

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).
