This European Standard has been prepared under a mandate given to CEN by the European Comm
20、ission and the European Free Trade Association. This European Standard is considered to be a supporting standard to those application and product standards which in themselves support an essential safety requirement of a New Approach Directive and which make reference to this European Standard.
