This European Standard applies to all ceramic tile grouts for internal and external tile installations on walls and floors. This standard describes the test method to be used to determine the compressive and flexural strength 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 can also be used for other types of tiles (natural and agglomerated stones, etc. ), where these do not adversely affect the stones.
