Thermal energy meters - Part 5: Initial verification tests

This document specifies initial verification tests for thermal energy meters. Thermal energy meters are instruments intended for measuring the energy which in a heat-exchange circuit is absorbed (cooling) or given up (heating) by a liquid called the heat-conveying liquid. The thermal energy meter indicates the quantity of thermal energy in legal units.
This document covers meters for closed systems only, where the differential pressure over the thermal load is limited.
This document is not applicable to:
-   electrical safety requirements;
-   pressure safety requirements; and
-   surface mounted temperature sensors.

Thermische Energiemessgeräte - Teil 5: Tests für Konformitätsuntersuchungen und Eichungen

Dieses Dokument legt Tests für Konformitätsuntersuchungen und Eichungen (Ersteichungen) für thermische Energiemessgeräte fest. Thermische Energiemessgeräte sind Messgeräte, die dazu bestimmt sind, die Energie zu messen, die in einem Wärmetauschkreislauf von einer als Wärmeträgerflüssigkeit bezeichneten Flüssigkeit aufgenommen (Kühlung) oder abgegeben (Heizung) wird. Das thermische Energiemessgerät zeigt die Menge der thermischen Energie in gesetzlichen Einheiten an.
Dieses Dokument behandelt nur Messgeräte für geschlossene Systeme, bei denen der Differenzdruck über die thermische Last begrenzt ist.
Dieses Dokument ist nicht anwendbar für:
—   Anforderungen an die elektrische Sicherheit;
—   Anforderungen an die Drucksicherheit;
—   oberflächenmontierte Temperaturfühler.

Compteurs d’énergie thermique - Partie 5 : Essais de vérification primitive

Le présent document spécifie les essais de vérification primitive pour les compteurs d’énergie thermique. Les compteurs d’énergie thermique sont des instruments destinés à mesurer l’énergie thermique qui, dans un circuit d’échange thermique, est absorbée (refroidissement) ou cédée (chauffage) par un liquide appelé « liquide caloporteur ». Le compteur d’énergie thermique fournit la quantité d’énergie thermique en unités de mesure légales.
Le présent document couvre les compteurs pour les systèmes fermés uniquement, où la pression différentielle dans la charge thermique est limitée.
Le présent document ne s’applique pas :
-   aux prescriptions de sécurité électrique ;
-   aux prescriptions de sécurité relatives à la pression ; ni
-   aux sondes de température montées en surface.

Merilniki toplote - 5. del: Preskusi prve overitve

Ta dokument določa preskuse prve overitve merilnikov toplote. Merilniki toplote so instrumenti, namenjeni merjenju energije, ki jo v krogotoku toplotne izmenjave absorbira (hlajenje) ali oddaja (ogrevanje) tekočina, imenovana tekočina za prenos toplote. Merilnik toplote podaja količino toplote v predpisanih enotah.
Ta dokument ne zajema zahtev za električno varnost.
Ta dokument ne zajema tlačnih varnostnih zahtev.
Ta dokument ne zajema površinsko nameščenih senzorjev temperature.
Ta dokument zajema samo števce za zaprte sisteme, pri katerih je diferencialni tlak nad toplotno obremenitvijo omejen.
