Hygrothermal performance of building components and building elements - Assessment of moisture transfer by numerical simulation

Le présent document spécifie les équations à utiliser dans le cadre d'une méthode de simulation numérique pour calculer le transfert non stationnaire de chaleur et d'humidité. Un exemple de référence est fourni et indique les tolérances admises pour la validation d'une méthode de simulation déclarée conforme au présent document. Les équations figurants dans le présent document ne peuvent pas être appliquées dans les cas suivants : lorsque la convection se produit par des trous et fissures ; les effets bidimensionnels jouent un rôle important ; des forces hydrauliques, osmotiques, électrophorétiques sont présentes ; les températures quotidiennes moyennes du composant dépassent 50 °C.

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!

- The UPSELL service allows you to easily update one of your standards.
- With a single click, add a new language, the Requirements or Redline+ service and add one or more additional users.
- Whether you are in the process of acquiring a standard or it is already available in your personal space, the UPSELL service is available at every stage to help you understand it and implement it within your organization.
