Electrolyte and water for vented Lead Acid accumulators - Part 2: Requirements for water

This part of IEC 62877 applies to water for use with vented lead-acid cells and batteries, i.e.
water for preparation of electrolyte and for topping up cells or batteries.
The purity of refilling water has to meet higher requirements compared to filling electrolyte,
because the impurities in the operating electrolyte will be gradually increased by regular
addition of water.
This international standard lays down requirements of the composition, purity and properties
of water in the absence of specific recommendations from the manufacturer.

Elektrolyte und Wasser für geschlossene Blei-Säure-Batterien - Teil 2: Anforderungen an Wasser

Electrolyte et eau pour accumulateurs plomb acide ouverts - Partie 2: Exigences pour l'eau

L'IEC 62877-2:2016 s'applique à l'eau destinée à être utilisée avec les éléments et les batteries ouvertes, c'est-à-dire l'eau pour la préparation de l'électrolyte et pour le remplissage de complément des éléments ou des batteries. La pureté de l'eau utilisée pour les remplissages de réapprovisionnement doit satisfaire à des exigences plus sévères que celles applicables à l'électrolyte de remplissage, car la part des impuretés contenues dans l'électrolyte de fonctionnement va progressivement augmenter avec l'ajout régulier d'eau. La présente norme internationale établit les exigences pour la composition, la pureté et les propriétés de l'eau en l'absence de recommandations spécifiques du fabricant.

Elektrolit in voda za oddušne svinčeve akumulatorje - 2. del: Zahteve za vodo

Ta del standarda IEC 62877 se uporablja za vodo, ki se uporablja z oddušnimi svinčevimi celicami in baterijami, tj. voda za pripravo elektrolita in za dolivanje celicam ali baterijam.
Čistost dolivanja vode mora izpolnjevati višje zahteve v primerjavi s polnjenjem elektrolita, ker se z običajnim dodajanjem vode količina nečistoč v delujočem elektrolitu postopoma veča.
Ta mednarodni standard določa zahteve za sestavo, čistost in lastnosti vode, kadar ni posebnih priporočil proizvajalca.

Part 2: Requirements for water

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 International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant sub
