European Standard





Language in which you want to receive the document


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.

Directives and Regulations

When the standard is harmonized under a directive or regulation, the word Harmonized appear. When such an inscription does not appear, it means that the standard is related to / supporting the relevant directive or regulation.
