Overview

This European Standard specifies a method for determining the chemical resistance and the resistance to stains of agglomerated stones with a polished surface after a prolonged contact with chemical materials. Resistance to a chemical attack is the characteristic which defines the behaviour of a floor/wall covering material in contact with chemically aggressive agents potentially able to react with the surface itself, and thereby either corrode it, penetrate it permanently or alter the visible aspect in some manner. The deteriorating action of the aggressive chemical can generate two different effects: Firstly, a real chemical action, according to which the alteration of the surface is due to the chemical reaction between the aggressive agent and some constituents of the surface itself. Secondly, a physical absorbing action, according to which the aggressive agent is able to penetrate the surface so that the removal is either extremely difficult or impossible. Both these actions can involve a modification of the visible appearance of the surface of the chemically attacked material, but only in the first case can the damage also introduce a modification in the physical and mechanical properties of the material itself. At present a DIN committee does not exist for EN 14617-10:2012 since the parties concerned have not shown any interest in work on the subject.
