(Main)Sanitary tapware - Mechanical mixing valves (PN 10) - General technical specifications
Sanitary tapware - Mechanical mixing valves (PN 10) - General technical specifications
This document specifies:
a) the field of application for mechanical mixing valves for use in a supply system of Type 1 (see Figure 1);
b) the dimensional, leak tightness, pressure resistance, hydraulic performance, mechanical strength, endurance, corrosion resistance of the surface of the product, sequence of testing and acoustic characteristics with which sanitary tapware products including their components (flexible hose, pull out spray) need to comply where applicable;
c) test methods to verify the characteristics.
The tests described in this document are type tests (laboratory tests) and not quality control or factory production control (FPC) tests carried out during manufacture.
This document applies to draw-off taps (mechanical mixing valves) for use with sanitary appliances installed in rooms used for personal hygiene (cloakrooms, bathrooms, etc.) and for food preparation (kitchens), i.e. for use with baths, wash basins, bidets, showers and sinks.
Figure 1 shows a supply system of Type 1 with a pressure range of (0,05 to 1,0) Mpa [(0,5 to 10) bar].
The conditions of use and classifications are given in Table 1.

Sanitärarmaturen - Mechanisch einstellbare Mischer (PN 10) - Allgemeine technische Spezifikation
Dieses Dokument legt Folgendes fest:
a) den Anwendungsbereich für mechanische Mischventile für die Anwendung in Wasserversorgungsanlagen des Typs 1 (siehe Bild 1);
b) die Maße, die Dichtheit, die Druckbeständigkeit, die hydraulische Leistung, die mechanische Festigkeit, die Dauerfestigkeit, die Korrosionsbeständigkeit der Oberfläche des Produkts, die Prüfreihenfolge und das Geräuschverhalten, denen sanitäre Armaturenprodukte und ihre Komponenten (Schlauch, ausziehbare Brause) entsprechen müssen, sofern zutreffend;
c) die Prüfverfahren, um diese Anforderungen nachzuweisen.
Die in diesem Dokument beschriebenen Prüfungen sind Typ-Anerkennungsprüfungen (Laborprüfungen) und keine Qualitätskontroll- oder werksseitigen Fertigungsprüfungen (en: factory production control, FPC), die während der Herstellung durchgeführt werden.
Dieses Dokument gilt für Ablaufarmaturen (mechanisch einstellbare Mischer) für die Ausrüstung von Sanitärausstattungsgegenständen, die in den der persönlichen Hygiene dienenden Räumen (Toiletten, Bäder usw.) und in Küchen für die Lebensmittelzubereitung installiert werden, d. h. für Badewannen, Waschbecken, Bidets, Brausen und Spülbecken.
Bild 1 zeigt eine Versorgungsanlage des Typs 1 mit einem Druckbereich von (0,05 bis 1,0) MPA [(0,5 bar bis 10) bar].
Die Anwendungsbedingungen und Klassifizierungen sind in Tabelle 1 dargestellt.

Robinetterie sanitaire - Mitigeurs mécaniques (PN 10) - Spécifications techniques générales
Le présent document spécifie :
a) le champ d’application des mitigeurs mécaniques destinés à être utilisés dans un système d’alimentation de type 1 (voir Figure 1) ;
b) les caractéristiques dimensionnelles, d’étanchéité, de résistance à la pression, de performance hydraulique, de résistance mécanique, d’endurance, de résistance à la corrosion de la surface du produit, de séquence d’essais et d’acoustique auxquelles les produits de robinetterie sanitaire, y compris leurs composants (tuyau flexible, douchette extractible), doivent répondre, le cas échéant ;
c) les méthodes d’essai permettant de vérifier ces caractéristiques.
Les essais décrits dans le présent document sont des essais de type (essais en laboratoire) et non des essais de contrôle qualité ou de contrôle de la production en usine (FPC, factory production control) réalisés en cours de fabrication.
Le présent document s’applique aux robinets de puisage (mitigeurs mécaniques) destinés à équiper les appareils sanitaires installés dans les locaux d’hygiène personnelle (toilettes, salles de bain, etc.) et dans les cuisines, c’est-à-dire les baignoires, lavabos, bidets, douches et éviers.
La Figure 1 illustre un système d’alimentation de type 1 dans une plage de pression de (0,05 à 1,0) MPa [de (0,5 à 10) bar].
Les conditions d’utilisation et la classification sont données dans le Tableau 1.
