Le présent document 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.

ZOOM ON ... the Requirements department
To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.

The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.
