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

Scope

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.
