Water meters - Part 4: Additional functionalities

This document specifies definitions, requirements and testing of additional functionalities for water meters, without metrological impact, in combination with Additional Functionality Devices (AFD) and in response to EU/EFTA Mandate M/441 EN. These AFDs are considered as “ancillary devices” as defined in EN ISO 4064-1:2017 and EN ISO 4064-4:2014.
This document does not cover the changing of metrological software within the meter or the upload/download of metrological software.
NOTE   A manufacturer can claim compliance only for additional functionalities described in this document. It is not mandatory that an AFD complies with all additional functionalities described herein.

Wasserzähler - Teil 4: Zusätzliche Funktionalitäten

Dieses Dokument legt Begriffe, Anforderungen und Prüfverfahren für zusätzliche Funktionalitäten für Wasserzähler ohne metrologische Auswirkungen in Kombination mit Zusatzfunktionsgeräten (ZFG) entsprechend EU/EFTA Mandat M/441 EN fest. Diese ZFGs gelten als „Zusatzgeräte“ nach der Definition in EN ISO 4064 1:2017 und EN ISO 4064 4:2014.
Dieses Dokument behandelt nicht die Änderung metrologischer Software innerhalb des Zählers oder deren Hoch-/Herunterladen.
ANMERKUNG   Ein Hersteller kann nur für in dieser Europäischen Norm beschriebene Zusatzfunktionen Konformität beanspruchen. Ein Zusatzfunktionsgerät (ZFG) muss nicht notwendigerweise alle in diesem Dokument definierten Funktionen beinhalten.

Compteurs d’eau - Partie 4 : Fonctionnalités additionnelles

Le présent document spécifie les définitions, exigences et essais des fonctionnalités additionnelles des compteurs d’eau, sans impact métrologique, en combinaison avec les dispositifs à fonctionnalités additionnelles (AFD) et en réponse au mandat UE/EFTA M/441 EN. Ces AFD sont considérés comme des « dispositifs auxiliaires » conformément à la définition de l’EN ISO 4064-1:2017 et de l’EN ISO 4064-4:2014.
Le présent document ne traite pas de la modification du logiciel à caractère métrologique dans le compteur ou du téléchargement d’un logiciel à caractère métrologique.
NOTE   Un fabricant peut déclarer la conformité uniquement pour les fonctionnalités additionnelles décrites dans le présent document. Il n’est pas obligatoire qu’un AFD soit conforme à toutes les fonctionnalités additionnelles décrites dans le présentee document.

Vodomeri - 4. del: Dodatne funkcije

Ta evropski standard določa definicije, zahteve in preskušanje dodatnih funkcij za vodomere, brez meroslovnega vpliva, v kombinaciji z napravami z dodatnimi funkcijami (AFD) in kot odziv na mandat EU/EFTA M/441 EN. Te naprave z dodatnimi funkcijami se upoštevajo kot »pomožne naprave«, kot je opredeljeno v standardu EN 14154-1.
Ta evropski standard ne zajema sprememb meroslovne programske opreme merilnika ali prenosa/nalaganja programske opreme merilnika.
OPOMBA:    Proizvajalec lahko navede skladnost le za dodatne funkcionalnosti, opisane v tem standardu. Ni obvezno, da je naprava z dodatnimi funkcijami skladna z vsemi dodatnimi funkcionalnostmi, opisanimi v tem dokumentu.
