Protection against pollution of water intended for human consumption in potable water installations and general requirements for devices to prevent pollution by backflow

This document specifies a methodology for protecting potable water in potable water installations within and outside buildings but within premises from the risk of pollution by backflow of non-potable water and gives recommendations on the design, risk analysis, backflow prevention devices and their installation methods.
This methodology is also intended to be used outside premises for all potable water systems connected to a potable water distribution system up to and including the point of use.
The product standards for the specific backflow prevention devices or arrangements are intended to be used in conjunction with this document. In the absence of a product standard, this document is intended to be used as a reference to draw up a specification for the development of new devices or arrangements.

Schutz des Trinkwassers vor Verunreinigungen in Trinkwasser-Installationen und allgemeine Anforderungen an Sicherungseinrichtungen zur Verhütung von Trinkwasserverunreinigungen durch Rückfließen

Dieses Dokument legt eine Methodik fest, um Trinkwasser in Trinkwasser-Installationen innerhalb von Gebäuden und außerhalb von Gebäuden, aber innerhalb von Grundstücken vor dem Risiko von Verunreinigungen durch das Rückfließen von Nichttrinkwasser zu schützen, und es gibt Empfehlungen zur Konstruktion, zur Risikoanalyse, zu Sicherungseinrichtungen gegen Rückfließen und zu deren Einbauverfahren.
Diese Methodik ist auch zur Anwendung außerhalb von Grundstücken bei allen Trinkwasser-Installationen gedacht, die mit einem Trinkwasser-Verteilungssystem verbunden sind, bis einschließlich der Entnahmestelle.
Es ist vorgesehen, die Produktnormen für die jeweiligen Armaturen oder Vorrichtungen zur Verhinderung des Rückfließens zusammen mit diesem Dokument zu verwenden. Falls keine Produktnormen vorhanden sind, ist dieses Dokument dazu vorgesehen, als Grundlage für die Beschreibung neuentwickelter Armaturen oder Vorrichtungen zu dienen.

Protection contre la pollution de l’eau destinée à la consommation humaine dans les installations d’eau potable et exigences générales applicables aux dispositifs de protection contre la pollution par retour

Le présent document spécifie une méthode de protection de l’eau potable dans des installations d’eau potable à l’intérieur et à l’extérieur des bâtiments, mais aussi dans les locaux, contre le risque de pollution par retour de l’eau non potable. Il donne également des recommandations sur la conception, l’analyse des risques, les dispositifs de protection contre les retours et leurs méthodes d’installation.
Cette méthode est également destinée à être utilisée en dehors des locaux, dans tous les réseaux d’eau potable raccordés à un réseau de distribution d’eau potable jusqu’au point d’utilisation inclus.
Les normes de produits concernant les dispositifs ou les systèmes de protection contre les retours spécifiques sont destinées à être utilisées conjointement avec le présent document. En l’absence d’une norme de produit, le présent document est destiné à être utilisé comme référence pour établir une spécification pour le développement de nouveaux dispositifs ou systèmes.
