Hygrothermal performance of building of equipment and industrial installations - Calculation of water vapour diffusion - Cold pipe insulations systems

Le présent document spécifie une méthode permettant de calculer, sous certaines conditions relatives à la différence de pression partielle de vapeur d'eau ainsi que les températures de l'air ambiant et de fluide circulant dans la tuyauterie, la densité du flux de vapeur d'eau dans les systèmes d'isolation ainsi que la quantité totale d'eau diffusée dans l'isolation en fonction du temps. La présente méthode s'applique aussi bien pour les tuyauteries situées à l'intérieur du bâtiment que celles situées à l'air libre. La température du fluide circulant dans la tuyauterie doit être supérieure à 0 °C.

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.

With Requirements, quickly access the main part of the normative text!
