Water conditioning equipment inside buildings - Nitrate removal devices - Requirements for performance, safety and testing
This European Standard specifies requirements relating to the construction and mode of operation and relevant methods for testing automatic, salt-regenerated, anion exchange nitrate removal devices for drinking water installations inside buildings, which are permanently connected to the mains supply.
NOTE Products intended for use in water supply systems are to comply, when existing, with national regulations and testing arrangements that ensure fitness for contact with drinking water. The Member State’s relevant regulators and the EC Commission agreed on the principle for 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. Until the EAS comes into force, the current national regulations remain applicable.
Anlagen zur Behandlung von Trinkwasser innerhalb von Gebäuden - Nitratentfernungsanlagen - 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 Anionenaustausches wirkende Nitratentfernungsgeräte für Trinkwasser-Installationen in Gebäuden, die dauerhaft an die Wasserversorgung angeschlossen sind, fest.
ANMERKUNG Produkte für die Verwendung in Wasserversorgungssystemen müssen, soweit 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. Bis das EAS in Kraft gesetzt ist, bleiben die derzeitigen nationalen Vorschriften anwendbar.
Appareils de traitement d'eau à l'intérieur des bâtiments - Dispositifs de dénitratation - Exigences de performances, de sécurité et d'essais
La présente Norme européenne spécifie les exigences relatives à la construction et au mode de fonctionnement des dispositifs de dénitratation automatiques, régénérés par le sel, échangeurs d’anions, utilisés dans les installations d’alimentation en eau potable à l’intérieur des bâtiments et raccordés en permanence à l’alimentation principale.
NOTE Les produits destinés à être utilisés dans les systèmes d’alimentation en eau doivent respecter, le cas échéant, les réglementations nationales et les dispositifs d’essai assurant leur adéquation pour être mis en contact avec de l’eau potable. Les organismes de réglementation des États membres correspondants et la Commission CE se sont mis d’accord sur le principe d’un Système européen d’acceptation unique (EAS), prévoyant des méthodes d’essai communes et une approbation à l’échelle européenne.
Si l’EAS est adopté ou quand il le sera, les Normes européennes relatives aux produits seront amendées par l’ajout d’une Annexe Z/EAS dans le cadre d’un Mandat M/136, comprenant des références formelles aux essais, à la certification et aux exigences de marquage des produits de l’EAS. Jusqu’à l’entrée en vigueur de l’EAS, les réglementations nationales actuelles restent en vigueur.
