Water meters for cold potable water and hot water - Part 1: Metrological and technical requirements (ISO 4064-1:2014)

ISO 4064-1:2014|OIML R 49-1:2013 specifies metrological and technical requirements of water meters for cold potable water and hot water flowing through a fully charged, closed conduit. These water meters incorporate devices which indicate the integrated volume.
In addition to water meters based on mechanical principles, ISO 4064-1:2014|OIML R 49-1:2013 applies to devices based on electrical or electronic principles, and mechanical principles incorporating electronic devices, used to measure the volume of cold potable water and hot water.
ISO 4064-1:2014|OIML R 49-1:2013 also applies to electronic ancillary devices. Ancillary devices are optional. However, it is possible for national or regional regulations to make some ancillary devices mandatory in relation to the utilization of water meters.

Wasserzähler zum Messen von kaltem Trinkwasser und heißem Wasser - Teil 1: Metrologische und technische Anforderungen (ISO 4064-1:2014)

Der vorliegende Teil der ISO 4064/OIML R 49 legt die metrologischen und technischen Anforderungen für Wasserzähler für kaltes Trink¬wasser und heißes Wasser fest, das durch eine vollkommen gefüllte, geschlossene Leitung fließt. Diese Wasserzähler sind mit Einrichtungen versehen, die das kumulierte Volumen anzeigen.
Zusätzlich zu den auf mechanischen Funktionsprinzipien beruhenden Wasserzählern gilt der vorliegende Teil der ISO 4064/OIML R 49 außerdem für Einrichtungen nach elektrischem oder elektronischem Funktions-prinzip und nach mechanischem Funktionsprinzip mit elektronischen Einrichtungen, die zur Messung des Volumens von kaltem Trinkwasser und heißem Wasser dienen.
Dieser Teil der ISO 4064/OIML R 49  gilt außerdem für elektronische Zusatzeinrichtungen. Zusatz-einrichtungen sind optional. Jedoch können in nationalen oder internationalen Regelungen einige Zusatzeinrichtungen hinsichtlich der Verwendung von Wasserzählern verbindlich vorgeschrieben sein.
ANMERKUNG   In den Anwendungsländern können nationale Vorschriften gelten.

Compteurs d'eau potable froide et d'eau chaude - Partie 1: Exigences métrologiques et techniques (ISO 4064-1:2014)

L'ISO 4064-1:2014|OIML R 49-1:2013 spécifie les exigences métrologiques et techniques applicables aux compteurs d'eau potable froide et d'eau chaude circulant dans une conduite fermée entièrement chargée. Ces compteurs d'eau comportent des dispositifs indiquant le volume compté.
En plus des compteurs d'eau dont le fonctionnement est basé sur des principes mécaniques, l'ISO 4064-1:2014|OIML R 49-1:2013 s'applique aux dispositifs dont le fonctionnement est basé sur un principe électrique ou électronique, ainsi qu'à un fonctionnement mécanique incluant des dispositifs électroniques utilisés pour mesurer le volume débité d'eau potable froide et d'eau chaude.
L'ISO 4064-1:2014|OIML R 49-1:2013 s'applique également à des dispositifs électroniques auxiliaires. Les dispositifs auxiliaires sont facultatifs. Il est cependant possible que des réglementations nationales ou régionales rendent certains dispositifs auxiliaires obligatoires selon l'utilisation du compteur d'eau.

Vodomeri za merjenje hladne pitne vode in vroče vode - 1. del: Metrološke in tehnične zahteve (ISO 4064-1:2014)

Standard EN ISO 4064-2 določa metrološke in tehnične zahteve za vodomere za merjenje hladne pitne vode in vroče vode, ki teče skozi zaprto cev s polnim pretokom. Ti vodomeri imajo vgrajene naprave, ki prikazujejo vgrajen pretok. Poleg mehansko delujočih vodomerov se ta del standarda ISO 4064|OIML R 49 uporablja za električno ali elektronsko delujoče naprave in naprave, delujoče na podlagi mehanskih načel z vgrajenimi elektronskimi napravami, ki se uporabljajo za merjenje pretoka hladne pitne vode in vroče vode. Ta del standarda ISO 4064|OIML R 49 se uporablja tudi za elektronske pomožne naprave. Pomožne naprave so izbirne. Kljub temu lahko nacionalni ali regijski predpisi določajo obvezno uporabo nekaterih pomožnih naprav v povezavi z uporabo vodomerov.

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.
