BS EN 12808-5:2008 PDF Download

BS EN 12808-5:2008 is a standard that applies to ceramic tile grouts used for both internal and external tile installations on walls and floors. The purpose of this standard is to determine the water absorption coefficient of grouts when in contact with water due to capillary action. This coefficient is measured using prisms.

The standard specifies the test method to be followed in order to determine the water absorption coefficient accurately. It does not provide any specific performance requirements or recommendations for the design and installation of ceramic tiles. However, it notes that ceramic tile grouts can also be used with other types of tiles such as natural and agglomerated stones, as long as they do not negatively affect these materials.
