This standard specifies a procedure for determiningThe hygric expansion or contractionbehaviour of building materials as a function of moisture content. It is applicable formineral, porous hygroscopic materials. For other materials showing moisture-induceddeformations,The procedure described can be applied in a suitable way taking intoaccountTheir specific moisture behaviour.
