Heat meters - Part 1: General requirements

This European Standard specifies the general requirements and applies to heat meters. Heat 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 heat meter indicates the quantity of heat in legal units.
Electrical safety requirements are not covered by this European Standard.
Pressure safety requirements are not covered by this European Standard.
Surface mounted temperature sensors are not covered by this European Standard.
This standard covers meters for closed systems only, where the differential pressure over the thermal load is limited.

Wärmezähler - Teil 1: Allgemeine Anforderungen

Diese Europäische Norm legt die allgemeinen Anforderungen für Wärmezähler fest. Wärmezähler sind Geräte, die dazu dienen, die Energiemenge zu messen, die in einem Wärmetauscherkreislauf durch eine als Wärmeträgerflüssigkeit bezeichnete Flüssigkeit aufgenommen (Kühlen) oder abgegeben (Heizen) wird. Der Wärmezähler zeigt die Wärmemenge in gesetzlichen Einheiten an.
Elektrische Sicherheitsanforderungen werden in dieser Europäischen Norm nicht behandelt.
Den Druck betreffende Sicherheitsanforderungen werden in dieser Europäischen Norm nicht behandelt.
Oberflächenmontierte Temperaturfühler werden in dieser Europäischen Norm nicht behandelt.
Die vorliegende Norm behandelt ausschließlich Zähler für geschlossene Systeme, in denen der Differenzdruck am Wärmeübertrager begrenzt ist.

Compteurs d'énergie thermique - Partie 1: Prescriptions générales

La présente Norme européenne spécifie les prescriptions générales relatives aux 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.
La présente Norme européenne ne traite pas des prescriptions de sécurité électrique.
La présente Norme européenne ne traite pas des prescriptions de sécurité relative à la pression.
La présente Norme européenne ne traite pas des sondes de température montées en surface.
La présente norme couvre les compteurs pour les systèmes fermés uniquement, où la pression différentielle dans la charge thermique est limitée.

Merilniki toplote - 1. del: Splošne zahteve

Ta evropski standard določa splošne zahteve in se uporablja za toplotne števce, tj. instrumente, ki so namenjeni za merjenje toplote, ki jo v krogotoku toplotne izmenjave absorbira (hlajenje) ali oddaja (ogrevanje) tekočina, imenovana tekočina za prenos toplote. Toplotni števec podaja toploto v predpisanih enotah. Ta evropski standard ne zajema električnih varnostnih zahtev. Ta evropski standard ne zajema tlačnih varnostnih zahtev. Ta evropski standard ne zajema površinsko nameščenih senzorjev temperature. Ta standard zajema samo števce za zaprte sisteme, kjer je diferencialni tlak nad toplotno obremenitvijo omejen.
