Chemicals used for treatment of water intended for human consumption - Silver salts for intermittent use
This European Standard is applicable to silver nitrate and silver sulfate and silver chloride for the preservation of water intended for human consumption in intermittent applications in:
- water supply plants, including their pipeline networks (small-size plants);
- water for the preparation of foodstuffs;
- water which is stored in packaged form or kept in enclosed systems (for example, water supply systems in land, water and airborne vehicles).
The purpose of adding silver salts is to prevent the detrimental proliferation of microorganisms in water during storage or in enclosed supply systems.
This European Standard describes the characteristics of silver salts, specifies the requirements for silver salts and gives reference to the analytical methods. It gives information on their use in water treatment. It also determines the rules relating to safe handling and use of silver salts (see Annex B).
Produkte zur Aufbereitung von Wasser für den menschlichen Gebrauch - Silbersalze für den nicht systematischen Gebrauch
Diese Europäische Norm gilt für Silbernitrat und Silbersulfat zur Konservierung von Wasser für den menschlichen Gebrauch bei nicht systematischen Anwendungen:
in Wasserversorgungsanlagen einschließlich deren Leitungsnetzen (Kleinanlagen);
für die Konservierung von Wasser für die Lebensmittelzubereitung;
für die Konservierung von sonstigem Wasser, das in abgepackter Form gelagert wird oder in geschlossenen Systemen (wie z. B. Wasserversorgungssysteme von Land-, Wasser- und Luftfahrzeugen) geführt wird.
Durch den Zusatz von Silbersalz soll eine nachteilige Vermehrung von Mikroorganismen im Wasser während der Lagerung bzw. innerhalb der geschlossenen Versorgungssysteme verhindert werden.
Diese Europäische Norm beschreibt die Eigenschaften von Silbersalzen, legt die Anforderungen an Silbersalze fest und verweist auf die entsprechenden Analysenverfahren. Sie enthält Angaben zu deren Anwendung in der Wasseraufbereitung. Sie legt darüber hinaus Regeln für die sichere Handhabung und Verwendung von Silbersalzen fest (siehe Anhang B).
Produits chimiques utilisés pour le traitement de l'eau destinée à la consommation humaine - Sels d'argent pour usage intermittent
La présente Norme européenne s'applique au nitrate d'argent et au sulfate d'argent pour la conservation de l'eau destinée à la consommation humaine pour usage intermittent dans :
les usines d'alimentation en eau, y compris leur réseau de canalisation (usines de petite taille) ;
de l'eau destinée à la préparation des denrées alimentaires ;
de l'eau stockée sous emballage ou conservée en circuit fermé (exemple, les systèmes de distribution d'eau dans les véhicules terrestres, nautiques et aériens).
L'ajout des sels d'argent a pour but d'empêcher la prolifération préjudiciable de micro-organismes dans l'eau pendant le stockage ou dans les circuits de distribution fermés.
La présente Norme européenne décrit les caractéristiques des sels d'argent et en spécifie les exigences ainsi que les méthodes d'analyse correspondantes. Elle donne des informations pour leur emploi dans le traitement de l'eau. Elle fixe également les règles relatives à la sécurité d'emploi et de manipulation des sels d'argent (voir Annexe B).
Kemikalije, ki se uporabljajo za pripravo pitne vode - Srebrove soli za uporabo z občasnimi prekinitvami
Ta evropski standard obravnava srebrov nitrat, srebrov sulfat in srebrov klorid za zaščito pitne vode, ki se uporablja z občasnimi prekinitvami, v:
– vodovodnih objektih, vključno z njihovimi cevovodnimi omrežji (majhni obrati);
– vodi za pripravo živil;
– vodi, ki se hrani v pakirani obliki ali v zaprtih sistemih (na primer vodovodni sistemi v kopenskih, vodnih ali zračnih vozilih).
Z dodajanjem srebrovih soli se prepreči škodljivo širjenje mikroorganizmov v vodi med shranjevanjem ali v zaprtih sistemih oskrbe z vodo.
Ta evropski standard opisuje značilnosti srebrovih soli, določa zahteve zanje in se sklicuje na analizne metode. Standard podaja informacije o uporabi srebrovih soli pri pripravi vode. Določa tudi pravila za varno ravnanje s srebrovimi solmi in njihovo uporabo (glej dodatek B).

Limits are given for impurities commonly present in the products. Depending on the raw material and the manufacturing process other impurities may be present and, if so, this shall be notified to the user and when necessary to relevant authorities. Users of the products should check the national regulations in order to clarify whether it is of appropriate purity for the preservation of water intended for human consumption, taking into account water quality, required dosage, contents of other impurities and additives used in the products not stated in this product standard. Limits have been given for impurities and chemical parameters where these are likely to be present in significant quantities from the current production process and raw materials. If the production process or raw materials lead to significant quantities of impurities, by-products or additives being present, this shall be notified to the user. 4.2 Composition of commercial products !The content of silver salts shall not be less than a mass fraction of 99 %." 4.3 Impurities and main by-products The products shall conform to the requirements specified in Table 1.
