Lightning protection system components (LPSC) - Part 7: Requirements for earthing enhancing compounds

IEC 62561-7:2024 is available as IEC 62561-7:2024 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.IEC 62561-7:2024 specifies the requirements and tests for earthing enhancing compounds producing low resistance of an earth termination system. This third edition cancels and replaces the second edition published in 2018. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) Figure A.1 has been replaced with a simpler one that clearly shows the high and low corrosion load limits of the earth enhancing compounds without the need for special knowledge; b) pH measurement has been introduced.

Composants des systèmes de protection contre la foudre (CSPF) - Partie 7: Exigences pour les enrichisseurs de terre

IEC 62561-7:2024 est disponible sous forme de IEC 62561-7:2024 RLV qui contient la Norme internationale et sa version Redline, illustrant les modifications du contenu technique depuis l'édition précédente.L'IEC 62561-7:2024 spécifie les exigences et les essais pour les enrichisseurs de terre qui génèrent une faible résistance d'un réseau de prises de terre. Cette troisième édition annule et remplace la deuxième édition parue en 2018. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: a) la Figure A.1 a été remplacée par une figure plus simple, qui indique clairement les limites haute et basse de la force corrosive des enrichisseurs de terre sans nécessiter aucune connaissance particulière; b) le mesurage du pH a été ajouté.

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
in addition to other activities, IEC publishes Internatio
