Water conditioning equipment inside buildings - Softeners - Requirements for performance, safety and testing
This European Standard specifies requirements relating to the construction and mode of operation and relevant methods of testing of automatic, salt-regenerated, cation exchange softeners for drinking water installations inside buildings which are permanently connected to the mains supply.
Until EAS comes into force, the current national regulations remain applicable.
NOTE Products intended for use in water supply systems should comply, when existing, with national regulations and testing arrangements that ensure fitness for contact with drinking water. The Member States relevant regulators and the EC Commission agreed on the principle of a future unique European Acceptance Scheme (EAS) which would provide a common testing and approval arrangement at European level.
If and when the EAS is adopted, European Standards on products will be amended by the addition of an Annex Z/EAS under Mandate M/136 which will contain formal references to the testing, certification and product marking requirements of the EAS.
Anlagen zur Behandlung von Trinkwasser innerhalb von Gebäuden - Enthärter - Anforderungen an Ausführung, Sicherheit und Prüfung
Diese Europäische Norm legt Anforderungen hinsichtlich der Konstruktion und der Betriebsart sowie entsprechende Prüfverfahren an automatische, mit Salz regenerierte und nach dem Prinzip des
Kationaustausches wirkende Enthärter für Trinkwasser-Installationen in Gebäuden, die dauerhaft an die Wasserversorgung angeschlossen sind, fest.
Bis das EAS-System in Kraft tritt, haben die derzeitigen nationalen Bestimmungen weiterhin Bestand.
ANMERKUNG Produkte für die Verwendung in Wasserversorgungssystemen müssensollten, so weit vorhanden, die nationalen Bestimmungen und Prüfanordnungen erfüllen, die ihre Eignung für den Kontakt mit Trinkwasser bestätigen. Die für die Mitgliedstaaten zuständigen Behörden und die EU-Kommission haben sich auf die Prinzipien eines zukünftigen einheitlichen Europäischen Zulassungssystems (EAS) geeinigt, welches eine gemeinsame Prüf- und Zulassungsregelung auf europäischer Basis bietet.
Falls und sobald EAS eingeführt ist, werden die Europäischen Produktnormen um einen Anhang Z/EAS unter dem Mandat M/136 ergänzt, in welchem formale Verweise auf die Anforderungen für die Prüfung, die Zertifizierung und die Produktkennzeichnung im Rahmen des EAS gegeben werden.
Appareils de traitement d'eau a l'intérieur des bâtiments - Adoucisseurs - Exigences de performance, de sécurité et essais
La présente Norme européenne spécifie les exigences relatives à la construction, au mode de fonctionnement et aux méthodes d’essai correspondantes des adoucisseurs automatiques, échangeurs de cations, à sel régénérant, destinés à des installations d’alimentation en eau potable à l’intérieur des bâtiments et raccordés en permanence à l’alimentation principale.
Les réglementations nationales actuelles restent applicables tant que le Système européen d’acceptation (SEA) n’est pas entré en vigueur.
NOTE Il convient que les produits destinés à un usage dans des systèmes d’alimentation en eau soient conformes, le cas échéant, aux réglementations nationales et aux montages d’essai qui assurent l’aptitude au contact avec l’eau potable. Les organismes de réglementation concernés des États membres et la Commission des communautés européennes se sont mis d’accord sur le principe d’un futur SEA unique définissant des montages d’essai et de validation communs au niveau européen.
À partir de l’adoption du SEA, le cas échéant, les Normes européennes relatives aux produits seront amendées par l’ajout de l’Annexe Z/SEA sous le mandat M/136 qui comportera les références formelles des exigences du SEA en matière d’essais, de certification et de marquage du produit.

The capacity of the salt tank shall be such that it permits a minimum of five regenerations between refills. 4.3.7 Continuity of supply during regeneration The softener design shall permit continuity of water supply during regeneration (see 7.4.3). 4.3.8 Protection against backflow and infiltration of brine a) Softener shall include a device to prevent backflow into the main supply, in accordance with the national implementation of EN 1717. If such a device is not evident, the softener shall be tested in accordance with 7.4.4.1. These shall be no water or brine collected from the vacuum reservoir. b) Infiltration of brine into the softened water supply during normal operation shall also be verified by testing in accordance with 7.4.4.2. In no outlet samples, the chloride concentration shall exceed
