Re: CE Marking - Is self-certification OK?
The CE marking directive does not apply to automobiles and parts.(I ssume your parts are automotive if not , the Machinery directive woulds apply.)
The EC Whole Vehicle Type-Approval (WVTA) system applies to passenger cars and to motorcycles on a mandatory basis since January 1998 and June 2003, respectively. As a result, these categories of vehicles must comply with all the relevant EC type-approval directives in order to be placed on the market
The certification of automotive parts is via Directive2007/46/EC,http://ec.europa.eu/enterprise/automotive/directives/vehicles/2007_46_ce.html
Hope this helps,
