CISPR 25 is the international standard titled "Radio disturbance characteristics for the protection of receivers used on board vehicles, boats, and on devices – Limits and methods of measurement."

Introduces robust test setups and limits for high-voltage (HV) components, shielding, and power inverters.

The standard is divided into two primary test categories: The official current version is CISPR 25:2021 (Edition 5

To ensure accuracy, safety, and legal compliance, always obtain standards from authorized distributors.

Engineers working on legacy vehicle platforms or maintaining older EMC test setups may require the 2002 edition for baseline compliance or system troubleshooting. The 2002 version, with its focus on frequencies up to 1,000 MHz, is a key reference for understanding the evolution of test limits and procedures. For instance, the Chinese standard is a direct adoption (identical) of CISPR 25:2002, with its technical content being mandatory from 2003 onwards.

For a more detailed look at the differences, you can compare the 2002 version and the 2021 version on the official IEC store. To ensure your product meets the latest requirements,
