Thermal energy meters - Part 4: Pattern approval tests

This European Standard specifies pattern approval 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 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.

Thermische Energiemessgeräte - Teil 4: Prüfungen für die Bauartzulassung

Diese Europäische Norm legt Prüfungen für die Bauartzulassungen für thermische Energiemessgeräte
fest. Thermische Energiemessgeräte sind Geräte, die dazu dienen, die Energiemenge zu messen, die in
einem Wärmeübertragerkreislauf durch eine als Wärmeträgerflüssigkeit bezeichnete Flüssigkeit
aufgenommen (Kühlen) oder abgegeben (Heizen) wird. Das thermische Energiemessgerät 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
über die Wärmemenge begrenzt ist.

Compteurs d'énergie thermique - Partie 4 : Essais en vue de l'approbation de modèle

La présente Norme européenne spécifie les essais en vue de l'approbation de modèle 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.
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 - 4. del: Preskusi za odobritev tipa (vključno z dopolnilom A1)

Ta evropski standard določa preskuse za odobritev tipa 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 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.
