Publisher's Synopsis
This report should allow those already familiar with basic EMC principles to appreciate the issues which are specific to the EMC of automobiles. These include the very severe radiated electromagnetic environment which they encounter, the difficulties of testing a large product at very high levels of radiated fields, the severe nature of the vehicle power supply transients, the need for achieving EMC at very low or negligible on-cost and the publication of the directive commonly known as the Automotive EMC Directive in November 1995, which takes cars and trucks out of the scope of 89/336/EEC, the general EMC Directive.;The publication then describes measurement methods for automotive EMC phenomena; the methods include texts on whole vehicles and on individual components. The various appropriate EMC standards and the "Automotive EMC Directive 95/54/EC are thoroughly discussed in an appendix.;By understanding the special requirements of the automotive industry, design engineers should be able to design their products to incorporate the required EMC performance. Engineers should also save the high costs associated with having inappreopriate EMC tests performed and avoid the possible product-liability claims arising from accidents following failure of a vehicle system as a result of electromagnetic interference.;This report should be useful to all vehicle and component designers, manufacturers, aftermarket equipment suppliers and test houses, as well as to suppliers of components and equipment for achieving EMC. It incorporates the provisions of the Automotive EMC Directive, published 8th November 1995, and implemented 1 January 1996 and, therefore, updates and replaces ERA report 94-0049.
