Certificates of conformity - History and legislation
In March 1992, the EU Council formally adopted the few remaining pieces of component-related legislation that are necessary to make the whole-vehicle type approval a reality for passenger cars. In June 1992, EU member state officials approved the adoption of EU legislation creating a single system for the certification of passenger cars, in turn defining the safety, and other technical requirements. The legislation established an EU type approval system to replace the national schemes of the twelve member states. In 1996, the EU type approval system became mandatory. Vehicles with an EU type approval can be marketed anywhere in the European Community. Therefore, a vehicle only needs to receive the type approval certification in one EU country in order to be accepted in all of the other member countries.
