This European Standard applies to all forms of wallcovering products in roll and panel form as defined in EN 235 supplied for hanging onto internal walls, partitions or ceilings, by means of an adhesive, whose primary purpose is decorative. However, certain wallcovering products may confer minor sound absorbtion and thermal resistance properties. It also provides for the evaluation of conformity of products to the requirements of this standard. It does not apply to wall coverings whose primary purpose is structural or protective (e.g. vapour or moisture barriers).
