Sanitary tapware - Thermostatic mixing valves (PN 10) - General technical specification

Edition date: 2026-03-18
In Force
Available languages: German, English, French
Summary: This document specifies general construction, performance and material requirements for PN 10 thermostatic mixing valves (TMV) and includes test methods for the verification of mixed water temperature performance at the point of use below 45 °C. This does not exclude the selection of higher temperatures where available. When these devices are used to provide anti-scald protection for children, elderly and disabled persons, the mixed water temperature needs to be set at a suitable temperature (body temperature approximately 38 °C). In particular children are at risk to scalding at lower temperatures than adults. This does not obviate the need for supervision of young children. It applies to valves intended for use on sanitary appliances in kitchens, washrooms (incl. all rooms with sanitary tapware, e.g. toilets and cloakrooms) and bath rooms operating under the conditions specified in Table 1. This document allows TMVs to supply a single outlet or a small number of outlets in a “domestic” application (e.g. one valve controlling a shower, bath, basin and/or bidet), excluding valves specifically designed for supplying a large number of outlets (i.e. for institutional use). The tests described are type tests (laboratory tests) and not quality control tests carried out during manufacture. Table 1 - Conditions of use [...table not reproduced...]

Le présent document spécifie des exigences générales relatives à la construction, aux performances et aux matériaux applicables aux mitigeurs thermostatiques PN 10 et comprend des méthodes d'essai permettant de vérifier les performances en température d'eau mitigée au point d'utilisation inférieur à 45 °C. Ces méthodes n'excluent pas la sélection de températures supérieures, si elles sont disponibles. Lorsque ces dispositifs sont utilisés pour assurer une protection contre les brûlures pour les enfants, les personnes âgées et les personnes présentant un handicap, la température de l'eau mitigée doit être réglée à une température appropriée (température du corps d'environ 38 °C). En particulier, les enfants sont exposés à un risque de brûlure à des températures plus basses que les adultes. Cela ne dispense pas de surveiller les enfants en bas âge. La présente norme s'applique aux mitigeurs destinés à l'équipement des appareils sanitaires installés dans les cuisines, les locaux d'hygiène corporelle (y compris tous les locaux équipés de robinetteries sanitaires, par exemple les toilettes et les vestiaires) et les salles de bains, et utilisés dans les conditions spécifiées dans le Tableau 1. Le présent document traite des mitigeurs thermostatiques avec une seule sortie ou un petit nombre de points de puisage, qui sont destinés à une utilisation « domestique » (par exemple, un mitigeur alimentant une douche, une baignoire, un lavabo et/ou un bidet). Sont exclus les mitigeurs spécialement conçus pour alimenter un grand nombre de sorties (par exemple, pour une utilisation dans une collectivité). Les essais décrits sont des essais de type (essais en laboratoire) et non des essais de contrôle qualité effectués en cours de fabrication. Tableau 1 — Conditions d'utilisation [table not reproduced]

Dieses Dokument legt allgemeine Anforderungen an Konstruktion (Ausführung), Verhalten (Funktion) und an Werkstoffe für thermostatische Mischer, PN 10, (Mischer) für den Niederdruckbereich fest und es enthält Prüfverfahren für die Verifizierung des Verhaltens der Mischwassertemperatur an der Entnahmestelle unter 45 °C. Das schließt die Auswahl höherer Temperaturen nicht aus, sofern sie verfügbar sind. Werden diese Vorrichtungen für die Bereitstellung des Verbrühungsschutzes für Kinder, ältere und behinderte Personen eingesetzt, muss die Mischwassertemperatur auf eine geeignete Temperatur (Körpertemperatur etwa 38 °C) eingestellt werden. Insbesondere bei Kindern besteht die Gefahr, sich bereits bei niedrigeren Temperaturen als Erwachsene zu verbrühen. Das macht jedoch nicht die Beaufsichtigung von Kleinkindern überflüssig. Es ist anwendbar für Armaturen die Verwendung an Sanitärausstattungsgegenständen in Küchen, Waschräumen (einschließlich aller Räume mit Sanitärarmaturen, z. B. Toiletten und Umkleideräume) und Bädern unter den in Tabelle 1 festgelegten Bedingungen. Dieses Dokument erlaubt die Verwendung von Mischern, die in Anlagen mit nur einer oder wenigen Entnahmestellen im häuslichen Bereich verwendet werden (z. B. ein Mischer für Brause, Badewanne, Waschbecken und/oder Sitzwaschbecken). Ausgeschlossen sind jedoch Mischer, die speziell für die Versorgung einer großen Anzahl von Entnahmestellen ausgelegt sind (d. h. für die Verwendung in Reihenwaschanlagen). Die beschriebenen Prüfungen sind Typprüfungen (Laborprüfungen) und nicht als Prüfungen zur Qualitätskontrolle während der Herstellung vorgesehen.
