A CE Mark is a mandatory conformity marking for a product that is being marketing and sold within the European Economic Area (EEA). A CE Marking indicates to a customer that a product conforms to specific European technical standards, known as harmonised European Norms (hEN). Numerous household goods already display CE Marking.
