Water meters for cold potable water and hot water - Part 5: Installation requirements (ISO/DIS 4064-5:2023)

ISO 4064-5:2014 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 4064-5:2014 specifies criteria for the selection of single, combination and concentric water meters, associated fittings, installation, special requirements for meters, and the first operation of new or repaired meters to ensure accurate constant measurement and reliable reading of the meter.
In addition to meters based on mechanical principles, ISO 4064-5:2014 also applies to water meters based on electrical or electronic principles, and to water meters based on mechanical principles incorporating electronic devices, used to measure the volume of cold potable water and hot water. It also applies to electronic ancillary devices. Ancillary devices are optional. However, national or international regulations may make some ancillary devices mandatory in relation to the utilization of the water meter.
The recommendations of ISO 4064-5:2014 apply to water meters, irrespective of technology, defined as integrating measuring instruments continuously determining the volume of water flowing through them.

Wasserzähler zum Messen von kaltem Trinkwasser und heißem Wasser - Teil 5: Einbaubedingungen (ISO/DIS 4064-5:2023)

Der vorliegende Teil der 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.
Der vorliegende Teil der ISO 4064 legt Kriterien für die Auswahl von einzelnen Wasserzählern, Verbundzählern und konzentrischen Wasserzählern, zugehörigen Armaturen, den Einbau, besondere Anforderungen an Zähler und die Inbetriebnahme von neuen oder reparierten Zählern fest, um eine genaue konstante Messung und zuverlässige Ablesung der Zähler sicherzustellen.
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 mechanischem Funktionsprinzip mit elektronischen Einrichtungen, die zur Messung des Volumens von kaltem Trinkwasser und heißem Wasser dienen. Er gilt außerdem für elektronische Zusatzeinrichtungen. Zusatzeinrichtungen sind optional. In nationalen oder internationalen Vorschriften können allerdings einige Zusatzeinrichtungen hinsichtlich der Verwendung von Wasserzählern verbindlich vorgeschrieben sein.
Die Empfehlungen dieses Teils der ISO 4064 gelten für Wasserzähler unabhängig von der Technologie, die als integrierende Messgeräte das Volumen des sie durchlaufenden Wassers bestimmen.
ANMERKUNG   Im Verwendungsland gilt die nationale Gesetzgebung.

Compteurs d'eau potable froide et d'eau chaude - Partie 5: Exigences d'installation (ISO/DIS 4064-5:2023)

L'ISO 4064-5:2013 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 4064-5:2013 spécifie des critères pour le choix de compteurs d'eau individuels, combinés et concentriques, les accessoires associés, l'installation ainsi que des exigences spéciales pour la première mise en service de compteurs neufs ou réparés pour garantir un mesurage d'une exactitude constante et une lecture fiable du compteur.
En plus des compteurs dont le fonctionnement est basé sur des principes mécaniques, l'ISO 4064-5:2013 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. Les dispositifs auxiliaires sont facultatifs. Cependant, des réglementations nationales ou internationales peuvent rendre certains dispositifs auxiliaires obligatoires selon l'utilisation du compteur d'eau.
Les recommandations de l'ISO 4064-5:2013 s'appliquent aux compteurs d'eau, indépendamment de leur technologie, définis en tant qu'instruments de mesure totalisateurs de débit, déterminant de manière continue le volume de débit d'eau les traversant.

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 the ISO list of patent declarations received, www.iso.org/patents.

The committee responsible for this document is ISO/TC 30, Measurement of fluid flow in closed conduits,
Subcommittee SC 7, Volume methods including water meters. It supersedes ISO 4064-2:2005, which has
been technically revised.
ISO 4064 consists of the following parts, under the general title Water meters for cold potable water and
hot water:
— Part 1: Metrological and technical requirements
