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.

Overview

EN 15219:2006+A1:2007 is a CEN European Standard for water conditioning equipment inside buildings, specifically covering salt‑regenerated anion exchange nitrate removal devices permanently connected to the mains for drinking water installations. The standard defines requirements for construction, mode of operation, performance, safety and the relevant testing methods for automatic nitrate removal units intended to protect drinking water quality.

Key topics and technical requirements

The standard addresses both design and verification aspects relevant to manufacturers, test labs and specifiers. Major topics include:

• Scope and device types
  • Automatic, salt‑regenerated anion exchange nitrate removal devices (including duplex and mixed‑bed units where applicable).
• Materials and consumables
  • Requirement that the anion exchange resin is certified as suitable for the intended application.
  • Use of regenerating salt in accordance with EN 973 (sodium chloride commonly specified; some countries accept potassium chloride).
• Design and mechanical requirements
  • Hydrostatic and cyclic pressure resistance tests, end‑connection standards and drain arrangements.
  • Salt tank requirements (e.g., covered overflow, capacity for multiple regenerations).
  • Electrical safety in line with EN 60335‑1 and noise limits per EN ISO 3822.
• Operating performance
  • Automatic regeneration and manual override, monitoring devices (timers, flow integrators, exhaustion sensors).
  • Continuity of water supply during regeneration (duplex or bypass arrangements).
  • Operating range: permissible water and ambient temperature ranges and minimum supply pressure requirements.
• Safety and water quality protection
  • Backflow prevention and brine infiltration controls (tests reference EN 1717; chloride infiltration limits specified).
• Testing and documentation
  • Methods for measuring exchange capacity, brining efficiency, salt consumption, regeneration water volume, residual nitrate concentration and manufacturing tests. Annex A explains nitrate removal principles; Annex B covers installation, operation and maintenance.

Applications and who uses this standard

EN 15219 is practical for:

• Manufacturers of nitrate removal devices - to design and certify products for the European market.
• Testing laboratories and conformity assessors - to validate performance, safety and endurance.
• Plumbing designers, installers and consulting engineers - to specify compliant systems for buildings and ensure correct installation and maintenance.
• Water utilities and regulators - to assess fitness for contact with drinking water and ensure public health protection.

Related standards

Key referenced documents include:

• EN 973 (regenerating salt), EN 1717 (backflow protection), EN 14743 (combination softener devices), EN 60335‑1 (electrical safety), ISO/EN pipe thread and water quality test methods (EN ISO 228‑1, EN ISO 10304‑1, EN ISO 11885), EN ISO 3822 (noise).
  Note: national regulations remain applicable until any future European Acceptance Scheme (EAS) is adopted.
