Electrolyte and water for vented lead acid accumulators - Part 1: requirements for electrolyte
IEC 62877-1:2023 is available as IEC 62877-1:2023 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.
IEC 62877-1:2023 applies to electrolytes and their components used for filling vented lead acid batteries with dry-charged cells and for electrolyte replenishment, replacement or electrolyte density adjustment of batteries in operation. This document defines the composition, purity and properties of electrolyte, for application where specific instructions from the battery manufacturer are not available. This second edition cancels and replaces the first edition published in 2016. This edition includes the following significant technical changes with respect to the previous edition:
- Addition of the concentration values of halogens in Table 4.
Elektrolyt und Wasser für geschlossene Blei-Akkumulatoren - Teil 1: Anforderungen an den Elektrolyt
Electrolyte et eau pour accumulateurs plomb-acide ouverts - Partie 1: Exigences pour l'électrolyte
IEC 62877-1:2023 est disponible sous forme de IEC 62877-1:2023 RLV qui contient la Norme internationale et sa version Redline, illustrant les modifications du contenu technique depuis l'édition précédente.
L' IEC 62877-1:2023 s'applique aux électrolytes et à leurs composants utilisés pour le remplissage des batteries plomb-acide ouvertes avec éléments chargés secs et pour le réapprovisionnement, le remplacement de l'électrolyte ou le réglage de la densité de l'électrolyte des batteries en fonctionnement. Le présent document définit la composition, la pureté et les propriétés de l'électrolyte pour application en l'absence d'instructions spécifiques du fabricant de batteries. Cette deuxième édition annule et remplace la première édition parue en 2016. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:
- Ajout des valeurs de concentration des halogènes dans le Tableau 4.
