The EC mark means you have tested your product to the appropriate European Community directive and it passed and you are authorized to sell it all over Europe in the European community, who now share common standards. There are many directives and more coming. For example there is the Machinery Directive and the Electrical Directive. They are pretty comprehensive. My employer manufactures welding equipment. To get the CE approval we had to pass the "pull the handle off" test and (believe it or not) the raindrop test. Plus, of course various electrical tests. Most electrical or electronic items that are sold internationally now bear the CE mark, the size and proportions of which are also defined!
