Hygrothermal performance of building materials and products - Determination of water vapour transmission properties - Cup method

ISO 12572:2016 specifies a method based on cup tests for determining the water vapour permeance of building products and the water vapour permeability of building materials under isothermal conditions. Different sets of test conditions are specified. The general principles are applicable to all hygroscopic and non-hygroscopic building materials and products, including insulation materials and including those with facings and integral skins. Annexes give details of test methods suitable for different material types. The results obtained by this method are suitable for design purposes, production control and for inclusion in product specifications.

Hygrothermal performance of building materials and products - Determination of water vapour transmission properties

<p> La présente norme spécifie une méthode basée sur des essais en coupelle pour déterminer la perméance à la vapeur d'eau des produits pour le bâtiment ainsi que la perméabilité à la vapeur d'eau des matériaux pour le bâtiment dans des conditions isothermes. Différentes séries de conditions d'essai sont spécifiées. Les principes généraux sont applicables à tous les matériaux et produits de bâtiment hygroscopiques et non hygroscopiques, y compris ceux qui possèdent des parements et des revêtements intégrés. Les annexes fournissent des détails sur des méthodes d'essai convenant pour différents types de matériaux. La présente norme ne s'applique pas dans le cas d'éprouvettes dont l'épaisseur d'air équivalente pour la diffusion de la vapeur d'eau est inférieure à 0,1 m, du fait de l'incertitude croissante sur les résultats de mesure. Si l'épaisseur d'air équivalente mesurée est supérieure à 1 500 m, le matériau peut être considéré comme imperméable. Les résultats obtenus par cette méthode peuvent être utilisés pour la conception, pour le contrôle de la production et pour insertion dans les spécifications de produits. </p>

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.
