Influence of materials on water intended for human consumption - Influence due to migration - Part 3: Test method for ion exchange and adsorbent resins

This European Standard specifies a procedure to determine the migration of substances from ion exchange and adsorbent resin materials for use in contact with water intended for human consumption.
Resins comprise synthetic organic macromolecular materials.
The standard is applicable to resins of the following types:
- Ion exchange resins: used to modify the composition of water (e.g. softening by removal of calcium ions). They can be in either an anionic or cationic state.
- Adsorbent resins: used to lower the concentration of undesirable substances (usually organic pollutants) from water. They are used in a neutral state.

Einfluss von Materialien auf Wasser für den menschlichen Gebrauch - Einfluss infolge der Migration - Teil 3: Prüfverfahren für Ionenaustauscher und Adsorberharze

Diese Europäische Norm beschreibt ein Verfahren, um die Migration von Substanzen aus Ionenaustauschern und Adsorberharzen, zu ermitteln, die für den Einsatz in Kontakt mit Wasser für den menschlichen Gebrauch bestimmt sind.
Harze beinhalten synthetische organische makromolekulare Substanzen.
Die Norm ist anwendbar auf Harze der folgenden Typen:
-   Ionenaustauscher-Harze: um die Wasserbeschaffenheit (z. B. Entfernung von Calciumionen zur Enthärtung) zu verändern. Sie können sowohl Kationenaustauscher- wie auch Anionenaustauscherharze sein.
Adsorberharze: eingesetzt, um die Konzentration von unerwünschten Substanzen (normalerweise organische Schadstoffe) im Wasser zu verringern. Sie werden in neutralem Zustand eingesetzt.

Influence sur l'eau des matériaux destinés a entrer en contact avec l'eau destinée a la consommation humaine - Influence de la migration - Partie 3 : Méthode d'essai des résines adsorbantes et échangeuses d'ions

La présente Norme européenne spécifie une méthode permettant de déterminer la migration de substances a partir de matériaux provenant des résines adsorbantes et échangeuses d’ions utilisées en contact avec l’eau destinée a la consommation humaine.
Ces résines comprennent des matériaux macromoléculaires organiques synthétiques.
La présente norme s’applique aux résines des types suivants :
-   les résines échangeuses d’ions : Utilisées pour modifier la composition de l’eau (par exemple, adoucissement par élimination des ions calcium). Elles peuvent etre soit anioniques, soit cationiques ;
-   les résines adsorbantes : Utilisées pour abaisser la concentration de l’eau en substances indésirables (généralement des polluants organiques). Elles sont utilisées a l’état neutre.
