The Notified Body Operations Group (NBOG) published some new NBOG Best Practice Guides at the end of 2014. One of these guidance documents deals with renewal of EC product certification, and another one with reporting requirements for substantial changes. Both papers were added to the series of Decisions of the Medical Device Experience Exchange Group (EK-Med) of the German Central Authority of the Laender for Health Protection with regard to Medicinal Products and Medical Devices (ZLG).
