This European Standard specifies the test method to be used to determine the transverse deformation of cementitious ceramic tile adhesives and grouts. This European Standard is applicable to all cementitious ceramic tile adhesives and grouts for internal and external tile installations on floors and walls. It is not applicable to ceramic tile adhesives and grouts which possess elastomeric properties, such as many dispersions and reaction resin adhesives and grouts. This European Standard does not contain performance requirements or recommendations for the design and installation of ceramic tiles. NOTE Ceramic tile adhesives can also be used for other kinds of tiles (natural and agglomerated stones, etc.), where these do not adversely affect these materials.
