Sanitary tapware - Pressure flushing valves and automatic closing urinal valves PN 10

This document applies to flushing valves for WCs and valves for urinals, with automatic hydraulic closure, intended for:
-   WC pans EN 997;
-   single flush urinals EN 13407;
-   siphon acting urinals EN 13407.
It does not apply to no-contact detection valves.
It is intended to specify:
-   marking and identification, physico-chemical, dimensional, leaktightness, pressure behaviour, hydraulic, mechanical endurance and acoustic characteristics of flushing valves for WCs and urinals with automatic closure;
-   test methods used to verify these characteristics;
-   and to determine requirements for the atmospheric interrupter which shall be an integral part of the WC flushing valve.
It applies in the following pressure and temperature conditions:
Table 1 — Conditions of use for tapware
Dynamic Pressure range recommended for a good working   Urinals
WC DN 15
WC DN 20   0,1 MPa ≤ P ≤ 0,5 MPa
(1 bar ≤ P ≤ 5 bar)
   WC DN 25   0,08 MPa ≤ P ≤ 0,25 MPa
(0,8 bar ≤ P ≤ 2,5 bar)
   WC DN 32   0,08 MPa ≤ P ≤ 0,25 MPa
(0,8 bar ≤ P ≤ 2,5 bar)
Maximum static pressure   1 MPa (10 bar)
Water temperature   ≤ 25 °C
NOTE 1   Although this document limits the pressure for WC DN 25 and WC DN 32 valves till 0,25 MPa (2,5 bar), some European countries have legislation and recommendations for higher pressures.
Health and quality requirements in accordance to European and national legislation for final materials in contact with water intended for human consumption are not covered by this document.

-   WC Becken nach EN 997;
-   Verdrängungsbecken nach EN 13407;
-   Absaugurinale nach EN 13407.
Sie gilt nicht für berührungslos ausgelöste Armaturen.
Ihr Zweck ist die Festlegung von:
-   Anforderungen an Kennzeichnung und Markierung, an physikalisch chemische Eigenschaften, Maße, Dichtheit, Druckbeständigkeit, hydraulische Eigenschaften, mechanisches Zeitstandverhalten und Geräuschverhalten der WC Druckspüler und Urinaldruckspüler mit selbsttätigem Abschluss;
-   Verfahren zur Überprüfung dieser Eigenschaften;
-   Anforderungen an den Rohrunterbrecher, der integrierter Bestandteil des WC Druckspülers sein muss.
Sie findet unter folgenden Fließdruck  und Temperaturbedingungen Anwendung:
Tabelle 1 — Einsatzbedingungen für Armaturen
Empfohlener Fließdruckbereich für einwandfreien Betrieb   Urinal   0,1 MPa ≤ P ≤ 0,5 MPa
   WC DN 15   (1 bar ≤ P ≤ 5 bar)
   WC DN 20   
   WC DN 25   0,08 MPa ≤ P ≤ 0,25 MPa
      (0,8 bar ≤ P ≤ 2,5 bar)
   WC DN 32   0,08 MPa ≤ P ≤ 0,25 MPa
      (0,8 bar ≤ P ≤ 2,5 bar)
max. Ruhedruck   1 MPa (10 bar)
Wassertemperatur   ≤ 25 °C
ANMERKUNG 1   Obwohl dieses Dokument den Druck für WC DN 25 und WC DN 32 Druckspüler auf 0,25 MPa (2,5 bar) begrenzt, gibt es in einigen europäischen Ländern Gesetze und Empfehlungen für höhere Drücke.
Gesundheits  und Qualitätsanforderungen nach der europäischen und nationalen Gesetzgebung für Endmaterialien, die Kontakt mit Wasser für den menschlichen Gebrauch haben, werden in diesem Dokument nicht behandelt.

Robinetterie sanitaire - Robinets de chasse d'eau et d'urinoirs à fermeture hydraulique automatique PN 10

Le présent document s’applique aux robinets de chasses pour WC et aux robinets d’urinoirs, à fermeture hydraulique automatique, destinés aux :
-   cuvettes de WC, EN 997 ;
-   urinoirs à simple rinçage, EN 13407 ;
-   urinoirs à action siphonique, EN 13407.
Il ne s’applique pas aux robinets à détection sans contact.
Il a pour objet de fixer :
-   le marquage et l’identification, les caractéristiques physico-chimiques, dimensionnelles, d’étanchéité, de tenue en pression, hydrauliques, acoustiques, d’endurance mécanique des robinets de chasse d’eau et robinets d’urinoirs à fermeture automatique ;
-   les méthodes d’essais à employer pour vérifier ces caractéristiques ;
-   les exigences du rupteur atmosphérique qui doit faire partie intégrante du robinet de chasse d’eau.
Il s’applique dans les conditions de pression et température suivantes :
Tableau 1 — Conditions d’utilisation des robinetteries
Plage de pression dynamique recommandée pour un bon fonctionnement   Urinoirs
WC DN15
WC DN20   0,1 MPa ≤ P ≤ 0,5 MPa
(1 bar ≤ P ≤ 5 bar)
   WC DN25   0,08 MPa ≤ P ≤ 0,25 MPa
(0,8 bar ≤ P ≤ 2,5 bar)
   WC DN32   0,08 MPa ≤ P ≤ 0,25 MPa
(0,8 bar ≤ P ≤ 2,5 bar)
Pression statique maximale   1 MPa (10 bar)
Température de l’eau   ≤ 25 °C
NOTE 1   Bien que le présent document limite la pression pour les robinets de WC DN25 et WC DN32 à 0,25 MPa (2,5 bar), la législation et les recommandations de certains pays européens fixent des pressions plus élevées.
Le présent document ne traite pas des exigences de santé et de qualité fixées par la législation européenne et les réglementations nationales relatives aux matériaux finaux en contact avec l’eau destinée à la consommation humaine.
