CISPR 25 is an international standard (Edition 5.0; CISPR 25:2021) that contains limits and procedures to measure radio disturbances within the frequency range of 150 kHz to 2.5 GHz. This standard applies to any electronic or electrical component intended for use in vehicles, trailers, internal combustion engines, boats, and any electronic/electrical component design for use in other such devices.

The standard’s limits are designed to provide protection for receivers, which are installed within an automotive vehicle, from any disturbances made via components or modules within that vehicle. The process and limits for a complete vehicle (even if it’s connected to the power mains for charging purposes or not) and the methods and limits for components or modules are specified in the CISPR 25 standard.
