This European Standard applies to all ceramic tile grouts used for internal and external tile installations on walls and floors. This European Standard specifies the test method to be used to determine the abrasion resistance of ceramic tile grouts. This European Standard does not contain performance requirements or recommendations for the design and installation of ceramic tiles. NOTE - Ceramic tile grouts may also be used for other types of tiles (natural and agglomerated stones, etc.), where these do not adversely affect the stones
