Sanitary tapware - General specifications for aerators
This document specifies:
- the dimensional, mechanical, hydraulic and acoustic characteristics with which sanitary tapware aerators (with and without flow regulation) should comply;
- the procedures for testing these characteristics.
This document is applicable to:
- Sanitary tapware aerators intended to be mounted on tapware used with sanitary appliances in toilets, bathrooms and kitchens (e.g. single taps, combination tap assemblies, mechanical mixing valves, thermostatic mixing valves);
- Sanitary tapware aerators used under the following pressure and temperature conditions (see Table 1).
[Table 1: Conditions for the use of aerators]
NOTE 1 Sanitary tapware aerators can only be connected downstream of the obturator of the sanitary tapware product.
NOTE 2 For the purposes of brevity, sanitary tapware aerators will be detailed only as aerators in the rest of this document.
NOTE 3 The tests described in this document are type tests (laboratory tests) and not quality control tests carried out during manufacture.
NOTE 4 Aerator swivels are to be tested in combination with a specific aerator only and are therefore considered to be sanitary tapware accessories. (Testing of the stand-alone swivels is therefore not covered by the scope of this document. Where swivels are used they are considered to be part of the tapware constructions, e.g. for bidet taps).
Sanitärarmaturen - Allgemeine Anforderungen an Strahlregler
Dieses Dokument legt Folgendes fest:
— die maßlichen, hydraulischen und mechanischen Anforderungen sowie die Anforderungen an das Geräuschverhalten von Strahlreglern von Sanitärarmaturen (mit und ohne Mengenregulierung);
— die Prüfverfahren, um diese Anforderungen zu überprüfen.
Dieses Dokument ist anwendbar auf:
— Strahlregler von Sanitärarmaturen für den Anschluss an Armaturen, die mit Sanitärausstattungsgegenständen in Toiletten, Badezimmern und Küchen verwendet werden (z. B. Auslaufventile, Mischbatterien, Mischer, thermostatische Mischer);
— Strahlregler von Sanitärarmaturen, die unter den folgenden Druck und Temperaturbedingungen eingesetzt werden (siehe Tabelle 1).
Tabelle 1 — Anwendungsbedingungen für Strahlregler
Grenzwerte für die Anwendung Empfohlene Grenzwerte für eine einwandfreie Funktion
Fließdruck 0,05 MPa ≤ P ≤ 0,5 MPa 0,1 MPa ≤ P ≤ 0,5 MPa
(0,5 bar ≤ P ≤ 5 bar) (1 bar ≤ P ≤ 5 bar)
Temperatur ≤ 70 °C ≤ 65 °C
ANMERKUNG 1 Strahlregler von Sanitärarmaturen können nur hinter dem Absperrorgan der Sanitärarmatur angeschlossen werden.
ANMERKUNG 2 Der Kürze halber werden Strahlregler von Sanitärarmaturen im Rest dieses Dokuments lediglich als Strahlregler aufgeführt.
ANMERKUNG 3 Die in diesem Dokument beschriebenen Prüfungen sind Typ-Anerkennungsprüfungen (im Laboratorium) und nicht für die Fertigungskontrolle vorgesehen.
ANMERKUNG 4 Strahlreglergelenke sind ausschließlich zusammen mit einem spezifischen Strahlregler zu prüfen und daher als Zubehörteile für Sanitärarmaturen anzusehen. (Die Prüfung eigenständiger Gelenke liegt daher außerhalb des Anwendungsbereichs dieses Dokuments. Wenn Gelenke verwendet werden, werden sie als Teil der Armaturkontruktionen betrachtet, z. B. für Bidetarmaturen).
Robinetterie sanitaire - Spécifications générales pour les aérateurs
Le présent document spécifie :
- les caractéristiques dimensionnelles, mécaniques, hydrauliques et acoustiques auxquelles il convient que les aérateurs de robinetterie sanitaire (avec et sans régulation du débit) répondent ;
- les modes opératoires d’essai permettant de contrôler ces caractéristiques.
Le présent document est applicable :
- aux aérateurs de robinetterie sanitaire destinés à être montés sur les robinetteries équipant les appareils sanitaires installés dans les toilettes, les salles de bains et les cuisines (par exemple robinets simples, mélangeurs, mitigeurs mécaniques, mitigeurs thermostatiques) ;
- aux aérateurs de robinetterie sanitaire utilisés dans les conditions de pression et de température suivantes (voir le Tableau 1).
[Tableau 1 — Conditions d’utilisation des aérateurs]
NOTE 1 Ces aérateurs de robinetterie sanitaire doivent être connectés seulement à l’aval de l’obturateur du produit de robinetterie sanitaire.
NOTE 2 Pour alléger le texte, les aérateurs de robinetterie sanitaire seront simplement appelés « aérateurs » dans le reste du présent document.
NOTE 3 Les essais décrits dans le présent document sont des essais de type (essais en laboratoire) et non des essais de contrôle qualité effectués en cours de fabrication.
NOTE 4 Les joints articulés d’aérateurs doivent être soumis à l’essai uniquement avec un aérateur spécifique et ils sont donc considérés comme des accessoires de robinetterie sanitaire. (L’essai des joints articulés seuls n’est donc pas couvert par le domaine d’application du présent document. Lorsque des joints articulés sont utilisés, ils sont considérés comme faisant partie des constructions de robinetterie, par exemple pour les robinets de bidets).
Sanitarne armature - Splošne specifikacije za regulatorje pretoka
Ta dokument določa:
– mere ter mehanske, hidravlične in akustične značilnosti, ki jim naj ustrezajo regulatorji pretoka za sanitarne armature (z regulacijo pretoka in brez nje);
– postopke za preskušanje teh značilnosti.
Ta dokument se uporablja za:
– regulatorje pretoka za sanitarne armature, namenjene za namestitev na armature, ki se uporabljajo s sanitarnimi napravami v straniščih, kopalnicah in kuhinjah (npr. enojne pipe, kombinirane pipe, mehanski mešalni ventili, termostatski mešalni ventili);
– regulatorje pretoka za sanitarne armature, ki se uporabljajo v naslednjih tlačnih in temperaturnih pogojih:
Opomba 1: Regulatorje pretoka za sanitarne armature je mogoče priključiti samo za tesnilom sanitarne armature.
Opomba 2: Zaradi jedrnatosti se v preostalem delu tega dokumenta namesto izraza regulatorji pretoka za sanitarne armature uporablja samo izraz regulatorji pretoka.
Opomba 3: Preskusi, opisani v tem dokumentu, so tipski preskusi (laboratorijski preskusi) in ne kontrolni preskusi kakovosti, opravljeni med proizvodnjo.
