Thermal energy meters - Part 2: Constructional requirements

This European Standard specifies the constructional 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 2: Anforderungen an die Konstruktion

Diese Europäische Norm legt die Anforderungen an die Konstruktion von Wärmezählern 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 2 : Prescriptions de fabrication

La présente Norme européenne spécifie les prescriptions de fabrication 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.

This draft amendment is submitted to CEN members for enquiry. It has been drawn up by the Technical Committee CEN/TC 176.

This draft amendment A1, if approved, will modify the European Standard EN 1434-2:2015. If this draft becomes an amendment,
CEN members are bound to comply with the CEN/CENELEC Internal Regulations which stipulate the conditions for inclusion of
this amendment into the relevant national standard without any alteration.

This draft amendment was established by CEN in three official versions (English, French, German). A version in any other
language made by translation under the responsibility of a CEN member into its own language and notified to the CEN-CENELEC
Management Centre has the same status as the official versions.

CEN members are the national standards bodies of Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia,
Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania,
Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland,
Turkey and United Kingdom.

Recipients of this draft are invited to submit, with their comments, notification of any relevant patent rights of which they are
aware and to provide supporting documentation.
