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 14154-1:2005+A2, 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 14154-1:2005+A2:2011$ 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 équipement d'essai
Le présent document s’applique aux compteurs d’eau destinés à une utilisation résidentielle, commerciale, industrielle légère et industrielle, et spécifie les paramètres et les méthodes d’essai pour les compteurs d’eau, indépendamment des technologies de conception, comme spécifié dans "EN 14154-1:2005+A2", utilisés pour mesurer le volume réel d’eau potable froide ou d’eau chaude s'écoulant dans une conduite fermée et à 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 à l’endurance ou à la performance sous des grandeurs d’influence.
Les compteurs ainsi soumis à l’essai doivent être marqués de manière à indiquer sans ambiguïté la conformité partielle au présent document. 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.
Vodomeri - 3. del: Preskusne metode in oprema
Ta dokument velja za vodomere, namenjene stanovanjski, gospodarski, lahki industrijski in industrijski uporabi, ter določa preskusne parametre in preskusne metode za vodomere, ne glede na tehnologije načrtovanja, kot so opredeljene v EN 14154-1:2005+A2, uporabljene za merjenje dejanskega volumna čiste hladne pitne vode ali segrete vode, ki teče skozi popolnoma poln, zaprt vod. Ti vodomeri vsebujejo naprave, ki navajajo celoten volumen.
Kadar imajo vodomeri vrednost Q3 > 160 m3/h, se v program preskušanja lahko vključijo spremembe referenčnih pogojev za doseganje posameznih omejitev preskusnega laboratorija, kadar se preskuša vzdržljivost ali delovanje pri vplivnih veličinah.
Tako preskušeni vodomeri morajo biti označeni tako, da se nedvoumno navede delna skladnost s tem dokumentom. Za boljše označevanje je proizvajalec vodomera dolžan popolnoma razkriti konkretno neskladnost zaradi omejitev preskusnega laboratorija.

The administrative examination shall demonstrate that the water meter fulfils the respective requirements of Clause 4 of #EN 14154-1:2005+A2:2011$, which can be verified by administrative work and shall show that the meter is manufactured in conformity with it.

Where the initial error curve is close to the maximum permissible error at a point other than at Q1, Q2 or Q3, if this error can be shown to be typical of the meter type, the approving authority may choose to define an alternative flowrate for initial verification in the pattern approval certificate. b) Test the water meter without its supplementary devices (if any) attached; c) during a test hold all other influence factors at reference conditions; d) measure the errors (of indication) at other flowrates if required, depending on the shape of the error curve; e) calculate the relative error (of indication) for each flowrate. 5.3.4 Acceptance criteria a) The errors observed for each of the seven flowrates shall not exceed the maximum permissible errors. If the error observed on one or more meters is greater than the maximum permissible error at one flowrate only, the test at that flowrate shall be repeated. The test shall be declared satisfactory if two out of the three results lie within the maximum permissible error and the arithmetic mean of the results for the three tests at that flowrate is less than or equal to the maximum permissible error; b) if all the errors (of indication) of the water meter have the same sign, at least one of these errors shall not exceed one half of the maximum permissible error. In all cases this requirement shall be applied equitably with respect to the water supplier and the consumer. SIST EN 14154-3:2005+A2:2011
