This European Standard applies to wallcoverings in roll form supplied for hanging onto internal walls, partitions or ceilings, by means of an adhesive, whose primary purpose is decorative. However, certain wallcoverings in roll form may confer minor sound absorption and thermal resistance properties. The European Standards for wallcoverings in roll form to which this European Standard relates, and which provide additional product definitions and requirements, include the following: Finished wallpapers, wall vinyls and plastics wallcoverings (EN 233); Wallcoverings for subsequent decoration (EN 234); Textile wallcoverings (EN 266); Cork rolls (EN 13085); Heavy duty wallcoverings (EN 259-1). It also provides for the assessment and verification of constancy of performance (AVCP) and marking of these products. It does not apply to wallcoverings whose primary purpose is structural or protective (e.g. vapour or moisture).
