Provides designers, manufacturers and suppliers of electrical and electronic devices for use in vehicles, motor boats and spark-ignited, engine-driven devices with limits and methods of measurement to provide protection to the radiofrequency spectrum from radio disturbances. This Standard is identical with and has been reproduced from CISPR 12:1997.
