Hygrothermal performance of building materials and products - Determination of hygric expansion coefficient

This standard specifies a procedure for determining the hygric expansion or contraction behaviour of building materials as a function of moisture content. It isapplicable for mineral, porous hygroscopic materials. For other materials showing moisture-induced deformations, the procedure described can be adapted in a suitable way taking into account their specific moisture behaviour. This standard is relevant to material states when reversible expansion/contraction processes, may be assumed, but not states governed by irreversible process such as shrinkage after material production or after initial drying.

Wärme- und feuchtetechnisches Verhalten von Baustoffen und Bauprodukten - Bestimmung des hygrischen Dehnkoeffizienten

Diese Europäische Norm legt ein Verfahren zur Bestimmung des hygrischen Dehn- oder Schwindverhaltens von Baustoffen in Abhängigkeit von der Stoffeuchte fest. Es ist für mineralische, poröse hygroskopische Stoffe anwendbar. Für andere Materialien, die feuchtebedingt Verformungen aufweisen, kann das beschriebene Verfahren entsprechend angepaßt werden, wobei deren spezifisches Feuchteverhalten zu berücksichtigen ist.

Performance hygrothermique des matériaux et produits pour le bâtiment - Détermination du coefficient d'expansion hydrique

La présente norme spécifie une procédure permettant de déterminer le comportement d'expansion ou de contraction hygrique des matériaux de construction en fonction de leur teneur en humidité. Elle s'applique aux matériaux hygroscopiques minéraux poreux. Pour d'autres matériaux présentant des déformations dues à l'humidité, la procédure décrite peut être appliquée de manière adéquate en tenant compte de leur comportement spécifique sous l'effet de l'humidité.

Overview

EN 13009:2000 - a CEN standard - specifies a laboratory procedure to determine the hygric expansion coefficient of building materials and products. The standard addresses the hygrothermal behavior by quantifying expansion or contraction as a function of moisture content. It is aimed primarily at mineral, porous hygroscopic materials, and the method may be adapted for other materials exhibiting moisture-induced deformations. EN 13009:2000 applies where reversible moisture-related dimensional changes can be assumed, and is not intended for irreversible processes (for example, shrinkage after production or initial drying).

Key Topics

• Scope and applicability: Focus on mineral, porous hygroscopic building materials; adaptation guidance for other materials with moisture-induced deformation.
• Measurement objective: Determination of the hygric expansion coefficient - a parameter relating dimensional change to moisture content.
• Reversibility requirement: Method is applicable to states where expansion/contraction is reversible; excludes irreversible shrinkage stages.
• Test procedure principles: Controlled conditioning of specimens, monitoring of moisture content and dimensional change, and calculation of the hygric expansion as a function of moisture.
• Reporting: Results presented to support hygrothermal assessments, material specifications and quality control (expressed as expansion per moisture change).

Applications

EN 13009:2000 is practical for:

• Material manufacturers assessing dimensional stability of mineral-based products (bricks, mortars, plasters, ceramics).
• Testing laboratories performing hygrothermal characterization for product data sheets and certification.
• Design professionals and architects who need hygric expansion data for detailing and selecting materials in moisture-exposed environments.
• Building physicists and hygrothermal modelers integrating moisture-related dimensional change into simulation and durability analyses.
• Quality control and compliance where specification limits require verified hygric behavior to prevent cracking, deformation or failure in façades, claddings, and internal finishes.
