Progress toward a uniform standard for vehicular radiation

This paper follows the progress of the work done over the past thirty years on interference from motor vehicles. Early problems in the development of instrumentation are described as are the test programs which led to the development of standards designed to protect television reception from vehicular interference. Reference is made to European standards and the reasons why it has been impossible to arrive at conformity between the U. S. and European standards. Mention is made of the changing criteria for interference which is making it necessary to update the presently used U. S. standard, and the hope that the new specification will be compatible with the new international standard.
