This European Standard is applicable to the following three types of adhesives for ceramic tiles, i.e. cementitious ones for internal and external tile installations, dispersion and reaction resin ones for internal tile installations, on walls and floors. This European Standard gives the terminology concerning the products, working methods, application properties, etc, for ceramic tile adhesives. This European Standard specifies the performance requirements for the adhesives for ceramic tiles. It also specifies the appurtenant test methods, assessment and verification of constancy of performance (AVCP), as well as classification, designation and marking of adhesives for ceramic tiles. This European Standard does not provide criteria or recommendations for the design and installation of ceramic tiles. Ceramic tile adhesives may also be used for other types of tiles (natural and agglomerated stones, etc.), if they do not adversely affect these materials.
