This European Standard specifies the methods for determining characteristics for adhesives used in internal and external installation of ceramic tiles. This European Standard does not contain performance requirements or recommendations for the design and installation of ceramic tiles. The following test methods are described: ¾ð Determination of open time (8.1) ¾ð Determination of slip (8.2) ¾ð Determination of tensile adhesion strength for cementitious adhesives (8.3) ¾ð Determination of shear adhesion strength of dispersion adhesives (8.4) ¾ð Determination of shear adhesion strength of reaction resin adhesives (8.5) ¾ð Determination of transverse deformation (8.6) NOTE Ceramic tile adhesives can be used also for other kinds of tiles (natural and agglomerated stones etc.), if they do not adversely affect the stones.
