isik või organ, kes on tunnistatud sõltumatuks antud küsimuses osalevatest osapooltest. Osapoolteks on tavaliselt tarnija ("esimene osapool") ja ostja ("teine osapool").
The Guide (Fiche II/B IV) states "Notified bodies are and must remain third parties. As third parties they should remain independent of their clients and other interested parties. ... Facilities such as laboratories or inspectorates owned by economic operators (first or second parties) cannot be notified separately".
