OIML Certificates of Conformity can be issued for water meters under the scope of the OIML Certificate System, provided that ISO 4064-2:2014|OIML R 49-2:2013, ISO 4064‑1:2014|OIML R 49‑1:2013 and ISO 4064‑3:2014|OIML R 49‑3:2013 are used in accordance with the rules of the system.
ISO 4064-2:2014|OIML R 49-2:2013 sets out details of the test programme, principles, equipment and procedures to be used for the type evaluation, and initial verification of a meter type.
The provisions of ISO 4064-2:2014|OIML R 49-2:2013 also apply to ancillary devices, if required by national regulations.
The provisions include requirements for testing the complete water meter and for testing the measurement transducer (including the flow or volume sensor) and the calculator (including the indicating device) of a water meter as separate units.

Wasserzähler zum Messen von kaltem Trinkwasser und heißem Wasser - Teil 2: Prüfverfahren (ISO 4064-2:2014)

Der vorliegende Teil der ISO 4064/OIML R 49 gilt für die Baumusterprüfung und die Ersteichung von Wasser-zählern für kaltes Trinkwasser und heißes Wasser, die in ISO 4064 1:2014/OIML R 49 1:2013 definiert sind. Die OIML Konformitätszertifikate können für Wasserzähler ausgestellt werden, die in den Anwendungsbereich des OIML-Zertifizierungssystems fallen, vorausgesetzt, dass dieser Teil der ISO 4064/OIML R 49, ISO 4064 1:2014/OIML R 49 1:2013 und ISO 4064-3:2014/OIML R49 3:2013 in Über¬einstimmung mit den Regeln des Systems angewendet werden.
Der vorliegende Teil der ISO 4064/OIML R 49 legt die Einzelheiten des Prüfprogramms, Grundsätze, Aus¬rüstung und Verfahren fest, die für die Baumusterprüfung und die Ersteichung einer Zählerart zum Einsatz kommen.
Die Bestimmungen des vorliegenden Teils der ISO 4064/OIML R 49 gelten ebenfalls für Zusatzeinrichtung, sofern diese aufgrund nationaler Regelungen erforderlich sind.
Die Bestimmungen enthalten Anforderungen an die Prüfung des vollständigen Wasserzählers sowie an die Prüfung des Messwertgebers (einschließlich Durchfluss- und Volumensensor) und des Rechners (einschlie߬lich Anzeigeeinrichtung) von Wasserzählern als eigenständige Einheiten.

Compteurs d'eau potable froide et d'eau chaude - Partie 2: Méthodes d'essai (ISO 4064-2:2014)

Les dispositions incluent les exigences d'essai du compteur d'eau complet et des exigences d'essai du transducteur de mesure (incluant le capteur de débit ou de volume) et du calculateur (incluant le dispositif indicateur) d'un compteur d'eau en tant qu'unités séparées.

Vodomeri za merjenje hladne pitne vode in vroče vode - 2. del: Preskusne metode (ISO 4064-2:2014)

Standard EN ISO 4064-2 se uporablja za vrednotenje vrste vodomerov in začetno preverjanje vodomerov za hladno pitno vodo in vročo vodo, kot je določeno v standardih ISO 4064-1: 2014|OIML R 49-1: 2013. Certifikat o skladnosti OIML se lahko izda za vodomere, ki jih zajema sistem certificiranja OIML, če se ta del standardov ISO 4064|OIML R 49, ISO 4064-1: 2014|OIML R 49-1: 2013 in ISO 4064-3: 2014|OIML R 49-3: 2013 uporablja v skladu s predpisi sistema. Ta del standarda ISO 4064|OIML R 49 navaja podrobnosti preskusnega programa, načel, opreme in postopkov za vrednotenje vrste in začetnega preverjanja vodomera. Določila tega dela standarda ISO 4064|OIML R 49 se uporabljajo tudi za pomožne naprave, če to zahtevajo nacionalni predpisi. Ta določila vključujejo zahteve za preskušanje celotnega vodomera in za preskušanje merilnega pretvornika (vključno s senzorjem pretoka) ter kalkulatorja vodomera (vključno s prikazovalno napravo) kot ločenih enot.
