EVS-EN 13009:2000

This European Standard specifies a procedure for determining the hygric expansion or contraction behaviour of building materials as a property of moisture content. It is applicable 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 practically reversible expansion/contraction processes may be assumed, but excluding initial shinkage tests after material production. This procedure does not take precedence over material specific test methods.
