Water meters - Part 3 : Test methods and equipment
This document applies to water meters intended for residential, commercial, light industrial and industrial use, and specifies the test parameters and the test methods for water meters, irrespective of the design technologies, as specified in EN 14154-1, used to meter the actual volume of clean cold potable water or heated water, flowing through a fully charged, closed conduit. These water meters shall incorporate devices, which indicate the integrated volume.
In the case where water meters having a value of Q3 > 160 m3/h, the test schedule may make provisions for modification of the Reference Conditions, to meet individual test laboratory limitations, when testing specifically for endurance or for performance under Influence Quantities.
Meters thus tested shall be marked so as to unambiguously indicate part compliance with this document. To augment this marking the meter manufacturer shall, in addition, be obliged to fully disclose the specific non compliance(s)due to the test laboratory limitations.
Wasserzähler - Teil 3: Prüfverfahren und -einrichtungen
Dieses Dokument gilt für Wasserzähler, die für den Einsatz in privaten und gewerblichen Bereichen und in Bereichen der Leichtindustrie und Industrie bestimmt sind. Es legt, ungeachtet der Technologie, die Prüfparameter und Prüfverfahren für die in EN 14154-1 festgelegten Wasserzähler fest, die zur Messung des tatsächlichen Volumens von sauberem, kaltem Trinkwasser oder erwärmtem Wasser, das durch eine voll gefüllte, geschlossene Leitung fließt, eingesetzt werden. Diese Zähler müssen mit Einrichtungen versehen sein, die das summierte Volumen anzeigen.
Bei Wasserzählern mit einem Wert von Q3 > 160 m3/h dürfen zur Berücksichtigung von begrenzten Möglich-keiten in vorhandenen Prüflaboratorien im Prüfplan Veränderungen der Referenzbedingungen vorgesehen werden, insbesondere bei der Beständigkeitsprüfung und der Leistungsprüfung unter Einflussgrößen.
Bei der Kennzeichnung der auf diese Weise geprüften Zähler muss eindeutig darauf hingewiesen werden, dass sie dem vorliegenden Dokument nur teilweise entsprechen. Darüber hinaus ist der Zählerhersteller verpflichtet, diese Kennzeichnung mit einer umfassenden Beschreibung zu ergänzen, in der genau beschrieben wird, welche begrenzten Möglichkeiten im Prüflabor zu dieser Abweichung geführt haben.
Compteurs d'eau - Partie 3 : Méthodes et équipment d'essai
La présente Norme s'applique aux compteurs d'eau destinés a une utilisation résidentielle, commerciale, industrielle légere et industrielle, et spécifie les parametres et les méthodes d'essai pour les compteurs d'eau, indépendamment des technologies de conception, comme spécifié dans l'EN 14154-1, utilisés pour mesurer le volume réel d'eau potable froide ou d'eau chaude s'écoulant dans une conduite fermée et a pleine charge. Ces compteurs d'eau doivent comprendre des dispositifs indiquant le volume intégré.
Dans le cas de compteurs d'eau ayant une valeur de Q3 > 160 m3/h, le programme d'essai peut prévoir une modification des conditions de référence pour satisfaire aux limitations du laboratoire d'essais individuel, en cas d'essais spécifiques liés a l'endurance ou a la performance sous des grandeurs d'influence.
Les compteurs ainsi soumis a l'essai doivent etre marqués de maniere a indiquer sans ambiguité la conformité partielle a la présente norme. Pour compléter ce marquage, le fabricant du compteur est, en outre, obligé de déclarer explicitement la ou les non-conformité(s) spécifique(s) due(s) aux limitations du laboratoire d'essais.
