IEC 61557-6:2019 specifies the requirements applicable to measuring equipment for testing the effectiveness of protective measures of residual current devices (RCD) installed in TT, TN and IT systems. It is not the purpose of this document to verify the RCD according to their product standards. IEC 61557-6:2019 cancels and replaces the second edition published in 2007. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) addition of requirements for testing a new type of RCD; b) addition of requirements for type B RCDs (former Annex B); c) addition of new Annex B on recommended tripping times; d) alignment of the structure with that of the whole IEC 61557 series. LIEC 61557-6:2019 specifie les exigences applicables aux appareils de mesure destines a soumettre a essai lefficacite des mesures de protection des dispositifs a courant differentiel residuel (DDR) installes dans les reseaux TT, TN et IT. La presente norme na pas pour objet de verifier la conformite des DDR aux normes de produits associees. LIEC 61557-6:2019 annule et remplace la deuxieme edition parue en 2007. Cette edition constitue une revision technique. Cette edition inclut les modifications techniques majeures suivantes par rapport a ledition precedente: a) ajout dexigences pour les essais dun nouveau type de DDR; b) ajout des exigences pour les DDR de type B (ancienne Annexe B); c) ajout de lAnnexe B relative aux temps de declenchement recommandes; d) alignement de la structure sur lensemble de la serie IEC 61557.
