Chemicals used for treatment of water intended for human consumption - Iron (III) sulfate solution

This European Standard is applicable to iron (III) sulfate solution of various iron and/or acid contents (see 3.2) used for treatment of water intended for human consumption. It describes the characteristics of iron (III) sulfate solution and specifies the requirements and the corresponding analytical methods for iron (III) sulfate solution (analytical methods are given in Annex B) and gives information on its use in water treatment. It also determines the rules relating to safe handling and use of iron (III) sulfate solution (see Annex E).

Produkte zur Aufbereitung von Wasser für den menschlichen Gebrauch - Eisen(III)sulfat-Lösung

Diese Europäische Norm gilt für Eisen(III)sulfat-Lösung mit unterschiedlichen Eisen- und/oder Säuregehalten (siehe 3.2) zur Aufbereitung von Wasser für den menschlichen Gebrauch. Sie beschreibt die Eigenschaften der Eisen(III)sulfat-Lösung und legt die Anforderungen sowie die entsprechenden Analysenverfahren für die Eisen(III)sulfat-Lösung fest (Analysenverfahren sind in Anhang B enthalten). Sie enthält Angaben für dessen Anwendung in der Wasseraufbereitung. Sie legt darüber hinaus Regeln für die sichere Handhabung und Verwendung der Eisen(III)sulfat-Lösung fest (siehe Anhang E).

Produits chimiques utilisés pour le traitement de l'eau destinée à la consommation humaine - Sulfate de fer (III) liquide

La présente Norme européenne est applicable au sulfate de fer (III) liquide de différentes teneurs en fer et/ou en acide (voir 3.2) utilisé pour le traitement de l'eau destinée à la consommation humaine. Elle décrit les caractéristiques du sulfate de fer (III) liquide, spécifie les prescriptions et les méthodes d'analyse correspondantes concernant ce produit (les méthodes d'analyse sont données à l'Annexe B) et donne des informations pour son utilisation dans le traitement de l'eau. Elle fixe également les règles relatives à la sécurité d'emploi et de manipulation du sulfate de fer (III) liquide (voir Annexe E).

Kemikalije, ki se uporabljajo za pripravo pitne vode - Železov (III) sulfat v tekočem stanju

Ta evropski standard se uporablja za raztopino železovega (III) sulfata z različno vsebnostjo železa in/ali kisline (glejte točko 3.2), ki se uporablja za pripravo pitne vode. Navaja značilnosti raztopine železovega (III) sulfata, določa zahteve in ustrezne analitične metode za raztopino železovega (III) sulfata (analitične metode so navedene v dodatku B) ter podaja informacije glede njene uporabe pri pripravi vode. Določa tudi pravila za varno ravnanje z raztopino železovega (III) sulfata in njeno uporabo (glejte dodatek E).
