The manufacturer shall continuously update the EU declaration of conformity. In Norway, a declaration of conformity must be given in English or Norwegian. ​

The declaration of conformity shall contain all the information required for identification of the EU legislation to which the declaration relates. 

MDR and IVDR state the rules for determining risk classes, see additional information under Classification​ (in Norwegian). It is the manufacturer's responsibility to determine whether the device must be reclassified or assessed by a notified body.
