WC pans and WC suites with integral trap

This European Standard specifies constructional and performance requirements together with test methods for close-coupled suites, one-piece and independent WC pans with integral trap used for personal hygiene manufactured from glazed ceramics or stainless steel.
This European Standard does not apply to squatting toilets, WC pans without integral trap or flushing cisterns as separate appliances.
In the case of independent WC pans, the associated flushing cisterns and pressure valves are covered by other standards and the reference to cisterns in this standard is related only to the definition and requirements of flushing volume.
In the case of close-coupled suites and one-piece WCs, this standard also specifies design, performance requirements and the test methods for designated flushing cisterns with flushing mechanisms, inlet valves and overflows. For these products, this standard covers flushing cisterns designed to be connected to drinking water installations inside buildings.
Before installation of WCs, EN 12056-2 and national requirements need to be taken into consideration.

WC-Becken und WC-Anlagen mit angeformtem Geruchverschluss

Diese Europäische Norm legt die konstruktiven und funktionellen Anforderungen und Prüfverfahren für WC Kombinationen, Einstück WCs und WC Becken mit freiem Zulauf mit angeformtem Geruchverschluss zur persönlichen Hygiene, hergestellt aus Sanitärkeramik oder nichtrostendem Stahl, fest.
Diese Europäische Norm gilt nicht für Hock WCs, WC Becken ohne angeformten Geruchverschluss sowie Spülkästen als Einzelgegenstände.
Für WC Becken mit freiem Zulauf werden die zugehörigen Spülkästen und Druckspüler durch andere Normen abgedeckt. Der Verweis auf Spülkästen in dieser Norm gilt nur für die Definitionen und die Anforderungen an das Spülvolumen.
Für WC Kombinationen und Einstück WCs legt diese Norm zudem Konstruktions  und Leistungs-anforderungen und Prüfverfahren für die zugeordneten Spülkästen mit Spülmechanismus, Füllventil und Überlauf fest. Dabei gilt diese Norm für Spülkästen, die für den Anschluss an die Trinkwasser Installation in Gebäuden ausgelegt sind.
Vor dem Einbau von WCs müssen EN 12056-2 und nationale Bestimmungen berücksichtigt werden.

Cuvettes de WC et cuvettes à réservoir attenant à siphon intégré

La présente norme spécifie les caractéristiques relatives à la construction et aux performances, ainsi que les méthodes d’essai des cuvettes de WC indépendantes, monobloc et à réservoir attenant, à siphon intégré, en céramique émaillée ou en acier inoxydable, utilisées pour l’hygiène personnelle.
La présente norme ne s’applique pas aux sièges à la turque, aux cuvettes de WC sans siphon intégré, ni aux réservoirs de chasse seuls.
Pour les cuvettes indépendantes, les réservoirs et robinets de chasse associés sont traités dans d’autres normes. La référence aux réservoirs dans la présente norme ne concerne que la définition et des prescriptions relatives au volume de chasse.
Pour les cuvettes à réservoir attenant et les cuvettes monobloc, la présente norme spécifie également les caractéristiques relatives à la conception et aux performances, ainsi que les méthodes d’essai applicables aux réservoirs de chasse associés équipés d’un mécanisme de chasse, d’un robinet d’alimentation et d’un trop-plein. Pour ces produits, la présente norme traite des réservoirs de chasse conçus pour être raccordés aux réseaux d’eau potable à l’intérieur des bâtiments.
Avant l’installation de WC, l’EN 12056-2 et les prescriptions nationales doivent être prises en compte.

Straniščne školjke in straniščna oprema z integriranim sifonom

Ta evropski standard določa konstrukcijske zahteve in zahteve v zvezi z delovanjem ter preskusne metode za prigrajene naprave, enodelne in samostojne straniščne školjke z integriranim sifonom za osebno higieno, proizvedene iz glazirane keramike ali nerjavnega jekla.
Ta evropski standard se ne uporablja za čepeča stranišča, straniščne školjke brez integriranega sifona ali izplakovalnike kot ločene naprave.
V primeru samostojnih straniščnih školjk so povezani izplakovalniki in tlačni ventili zajeti v drugih standardih, pri čemer je sklicevanje na izplakovalnike v tem standardu povezano samo z opredelitvijo in zahtevami prostornine za izplakovalno vodo.
Ta standard za prigrajene naprave in enodelne straniščne školjke določa tudi zasnovo, zahteve glede zmogljivosti in preskusne metode za določene izplakovalnike z mehanizmi za izplakovanje, dovodnimi ventili ter prelivi. V zvezi s temi izdelki so v tem standardu obravnavani izplakovalniki, ki so namenjeni priključitvi na napeljave za pitno vodo v stavbah.
Pred vgradnjo straniščnih školjk ali naprav je treba upoštevati standard EN 12056 2 in nacionalne zahteve.
