Water meters for cold potable water and hot water - Part 4: Non-metrological requirements not covered in ISO 4064-1 (ISO/DIS 4064-4:2023)

ISO 4064-4:2014 applies to water meters used to meter the volume of cold potable water and hot water flowing through a fully charged, closed conduit. These water meters incorporate devices which indicate the integrated volume.
ISO 4064-4:2014 specifies technical characteristics and pressure loss requirements for meters for cold potable water and hot water. It applies to water meters which can withstand: a) a maximum admissible working pressure (MAP) equal to at least 1 MPa [0,6 MPa for meters for use with pipe nominal diameters (DNs) ≥500 mm]; b) a maximum admissible temperature (MAT) for cold potable water meters of 30 °C; c) a MAT for hot water meters up to 180 °C, depending on class.
In addition to meters based on mechanical principles, ISO 4064-4:2014 also applies to water meters based on electrical or electronic principles, and to water meters based on mechanical principles incorporating electronic devices, used to meter the volume flow of hot water and cold potable water. It also applies to electronic ancillary devices. As a rule ancillary devices are optional. However, national or international regulations may make some ancillary devices mandatory in relation to the utilization of the water meter.

Wasserzähler zum Messen von kaltem Trinkwasser und heißem Wasser - Teil 4: Nichtmetrologische Anforderungen, die nicht Gegenstand von ISO 4064-1 sind (ISO/DIS 4064-4:2023)

Dieser Teil von ISO 4064 gilt für Wasserzähler zur Volumenmessung von kaltem Trinkwasser und heißem Wasser, das durch eine vollständig gefüllte, geschlossene Leitung fließt. Diese Wasserzähler sind mit Einrichtungen versehen, die das kumulierte Volumen anzeigen.
Dieser Teil von ISO 4064 legt technische Eigenschaften und Anforderungen für den Druckverlust für Wasserzähler für kaltes Trinkwasser und heißes Wasser fest. Er gilt für Wasserzähler,
a)   die dem größten zulässigen Druck (MAP) von mindestens 1 MPa  [0,6 MPa bei Zählern für Rohre mit Nenndurchmessern (DN) ≥ 500 mm],
b)   die der höchsten zulässigen Temperatur (MAT) von 30 °C für Wasserzähler für kaltes Trinkwasser,
c)   die der höchsten zulässigen Temperatur (MAT), in Abhängigkeit von der jeweiligen Klasse, von bis zu 180 °C für Wasserzähler für heißes Wasser widerstehen können.
Zusätzlich zu den auf mechanischen Funktionsprinzipien beruhenden Wasserzählern gilt der vorliegende Teil der ISO 4064 ebenfalls für Wasserzähler, die auf elektrischen oder elektronischen Funktionsprinzipien beruhen und für Wasserzähler nach mechanischen Funktionsprinzipien mit elektronischen Einrichtungen, die zur Messung des Volumendurchflusses von heißem Wasser und von kaltem Trinkwasser dienen. Er gilt außerdem für elektronische Zusatzeinrichtungen. Zusatzeinrichtungen sind grundsätzlich optional. Jedoch können in nationalen oder internationalen Vorschriften einige Zusatzeinrichtungen hinsichtlich der Verwendung von Wasserzählern verbindlich vorgeschrieben sein.

Compteurs d'eau potable froide et d'eau chaude - Partie 4: Exigences non métrologiques non couvertes par l'ISO 4064-1 (ISO/DIS 4064-4:2023)

L'ISO 4064-4:2013 s'applique aux compteurs d'eau utilisés pour mesurer le volume d'eau potable froide et d'eau chaude s'écoulant dans une conduite fermée et à pleine charge. Ces compteurs d'eau comportent des dispositifs indiquant le volume compté.
L'ISO 4064-4:2013 spécifie les paramètres techniques et les exigences de perte de pression s'appliquant aux compteurs d'eau potable froide et d'eau chaude. Elle s'applique aux compteurs d'eau pouvant résister à: a) une pression de service maximale admissible (PMA) égale à au moins 1 MPa [0,6 MPa pour les compteurs équipant des conduites de diamètre nominal (DN) ≥ 500 mm]; b) à une température maximale admissible (TMA) allant de 30 ºC, pour les compteurs d'eau potable froide; c) jusqu'à 180 ºC pour les compteurs d'eau chaude, selon la classe.
En plus des compteurs dont le fonctionnement est basé sur des principes mécaniques, l'ISO 4064-4:2013 s'applique aussi aux compteurs d'eau dont le fonctionnement est basé sur un principe électrique ou électronique, ainsi qu'aux compteurs d'eau à fonctionnement mécanique incluant des dispositifs électroniques utilisés pour mesurer le volume débité d'eau chaude et d'eau potable froide. Elle s'applique également aux dispositifs électroniques auxiliaires. Généralement, les dispositifs auxiliaires sont facultatifs. Cependant, des réglementations nationales ou internationales peuvent rendre certains dispositifs auxiliaires obligatoires selon l'utilisation du compteur d'eau.
