Covers higher bands up to nearly 6 GHz to include technologies like (Vehicle-to-Everything) and New Receiver Protection: Adds specific categories for Wi-Fi, Bluetooth, and Satellite Navigation that were not present in earlier versions. Testing Changes: Includes new annexes for measurement uncertainty
Users often search for "free download" versions, but CISPR 25 is a proprietary standard published by the International Electrotechnical Commission (IEC). For legal compliance and up-to-date technical data, it must be acquired through official channels:
More detailed procedures for testing modules independently, which is crucial for Tier 1 suppliers. Key Testing Procedures Under CISPR 25:2021
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. What is CISPR 25
