CISPR 25:1995 ED1

Limits and methods of measurement of radio disturbance characteristics for the protection of receivers used on board vehicles

Scope

This standard is designed to protect receivers from disturbances
produced by conducted and radiated emissions arising in a vehicle.

Test procedures and limits given are intended to provide
provisional control of vehicle-radiated emissions, as well as
component/module conducted/radiated emissions of long and short
duration.

The standard:

- establishes a test method for measuring the electromagnetic
emissions from the electrical system of a vehicle;

- sets limits for the electromagnetic emissions from the electrical
system of a vehicle;

- establishes a test method for testing on-board components and
modules independent from the vehicle;

- sets limits for electromagnetic emissions from components to
prevent objectionable disturbance to on-board receivers;

- classifies automotive components by disturbance duration to
establish a range of limits.
