Looking for CEN will not be very successfull. You should have a look to DIN , EN, ISO and DIN-EN-ISO standards. DIN means Deutsche Industrie Norm ; EN means European Norm ; ISO means International Organization for Standardisation. The German DIN are leading all over Europe and more for industrial standards. Step by step the other European Countries have taken over the German DIN norms and so after a while, when all agreed, it becomes a DIN-EN. In the next step, when more countries out of Europe also haven taken over these standards, it becomes a DIN-EN-ISO. New Standards, which are developed by the experts of all involved countries together, will be an ISO from the beginning. What are you looking for in detail?
