Water meters for cold potable water and hot water - Part 4: Non- metrological requirements not covered in ISO 4064-1 (ISO 4064- 4:2014)

EN ISO 4064-4 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. This part of ISO 4064 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 pressure (MAP) equal to at least 1 MPa1) [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 of up to 180 °C, depending on class. In addition to meters based on mechanical principles, this part of ISO 4064 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 4064- 4:2014)

Diese Internationale Norm gilt für Wasserzähler zur Volumenmessung von kaltem Trinkwasser und heißem
Wasser, das durch eine vollständig gefüllte, geschlossene Leitung fließt. Diese Wasserzähler müssen mit
Einrichtungen versehen sein, die das summierte Volumen anzeigen.
Diese Norm legt technische Eigenschaften und Anforderungen für den Druckverlust für Wasserzähler für
kaltes Trinkwasser und heißes Wasser fest. Sie gilt für Wasserzähler, die den größten zulässigen Betriebsdrücken
(MAP) ≥ 1 MPa [0,6 MPa bei Zählern für Rohre mit Nenndurchmessern (DN) ≥ 500 mm] sowie in
Abhängigkeit von der jeweiligen Klasse einer höchsten zulässigen Temperatur (MAT) von 30 °C für Wasserzähler
für kaltes Trinkwasser und von 180 °C für Wasserzähler heißes Wasser widerstehen können.
Der vorliegende Teil der ISO 4064 gilt ebenfalls für Wasserzähler nach elektrischem oder elektronischem
Funktionsprinzip und für Wasserzähler nach mechanischem Funktionsprinzip mit elektronischen Einrichtungen,
die zur Messung des Durchflussvolumens 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 destinés au mesurage de l'eau potable froide et chaude - Partie 4: Exigences non métrologiques non couvertes par l'ISO 4064-1 (ISO 4064- 4:2014)

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.

Vodomeri za merjenje hladne pitne vode in vroče vode - 4. del: Nemetrološke zahteve, ki niso zajete v ISO 4064-1 (ISO 4064-4:2014)

Standard EN ISO 4064-4 se uporablja za vodomere za merjenje pretoka hladne pitne vode in vroče vode, ki teče skozi zaprto cev s polnim pretokom. Ti vodomeri imajo vgrajene naprave, ki prikazujejo vgrajen pretok. Ta del standarda ISO 4064 določa tehnične lastnosti in zahteve za izgubo tlaka pri vodomerih za hladno pitno vodo in vročo vodo. Uporablja se za vodomere, ki lahko prenesejo: a) največji dovoljeni tlak (MAP), ki je enak najmanj 1 MPa) [0,6 MPa za vodomere za uporabo s cevmi z nazivnimi premeri (DN) ≥500 mm], b) največjo dovoljeno temperaturo (MAT) za vodomere za hladno pitno vodo 30 °C, c) MAT za vodomere za vročo vodo do 180 °C, odvisno od vrste. Poleg mehansko delujočih vodomerov se ta del standarda ISO 4064 uporablja za električno ali elektronsko delujoče vodomere in vodomere, delujoče na podlagi mehanskih načel z vgrajenimi elektronskimi napravami, ki se uporabljajo za merjenje pretoka hladne pitne vode in vroče vode. Uporablja se tudi za elektronske pomožne naprave. Praviloma so pomožne naprave izbirne. Kljub temu lahko nacionalni ali mednarodni predpisi določajo obvezno uporabo nekaterih pomožnih naprav v povezavi z uporabo vodomerov.

Foreword

ISO (the International Organization for Standardization) is a worldwide federation of national standards

bodies (ISO member bodies). The work of preparing International Standards is normally carried out

through ISO technical committees. Each member body interested in a subject for which a technical

committee has been established has the right to be represented on that committee. International

organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.

ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of

electrotechnical standardization.

The procedures used to develop this document and those intended for its further maintenance are

described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the

different types of ISO documents should be noted. This document was drafted in accordance with the

editorial rules of the ISO/IEC Directives, Part 2, www.iso.org/directives.

Attention is drawn to the possibility that some of the elements of this document may be the subject of

patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of any

patent rights identified during the development of the document will be in the Introduction and/or on

Water meters for cold potable water and hot water —
Part 4:
Non-metrological requirements not covered in ISO 4064-1
1 Scope

This part of ISO 4064 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.

This part of ISO 4064 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 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 of up to 180 °C, depending on class.

In addition to meters based on mechanical principles, this part of ISO 4064 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.
