Heat meters - Part 2: Constructional requirements

This European Standard specifies the constructural requirements and applies to heat meters, that is to instruments intended for measur¬ing the heat which, in a heat-exchange circuit, is absorbed or given up 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.

Wärmezähler - Teil 2: Anforderungen an die Konstruktion

Diese Europäische Norm gilt für Wärmezähler, d. h. für Geräte, die dazu dienen, die Wärmemenge zu
messen, die in einem Wärmetauscherkreislauf durch eine als Wärmeträgerflüssigkeit bezeichnete Flüssigkeit
aufgenommen oder abgegeben wird. Der Wärmezähler zeigt die Wärmemenge in gesetzlichen Einheiten an.
Elektrische Sicherheitsanforderungen werden in dieser Norm nicht behandelt.
Den Druck betreffende Sicherheitsanforderungen werden in dieser Norm nicht behandelt.
Oberflächenmontierte Sensoren werden in dieser Norm nicht behandelt.
Teil 1 beschreibt allgemeine Anforderungen.

Compteurs d'énergie thermique - Partie 2: Prescriptions de fabrication

La présente Norme européenne spécifie les prescriptions de fabrication et s'applique aux compteurs d'énergie thermique, c'est-à-dire aux instruments destinés à mesurer l'énergie thermique qui, dans un circuit d'échange thermique, est absorbée (refroidissement) ou cédée (échauffement) 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 exigences de sécurité électrique.
La présente Norme européenne ne traite pas des exigences de sécurité relative à la pression.
La présente Norme européenne ne traite pas des sondes de température montées en surface.
