Re: [PSES] Automotive Directive 2004/104/EC and EN 55012

The EC directive (and related documents) have tests to protect both on-board and off-board receivers. The vehicle test is practically the same as CISPR 12 and 55012. Luke Turnbull -Original Message- From: T.Sato [mailto:vef00...@nifty.ne.jp] Sent: 11 June 2014 13:09 To: EMC-PSTC
