This standard specifies a procedure for determining the hygric expansion or contraction behaviour of building materials as a function of moisture content. It is applicable for mineral, porous hygroscopic materials. For other materials showing moisture-induced deformations, the procedure described can be applied in a suitable way taking into account their specific moisture behaviour.
