1 Scope
This document specifies a method for determination of the chemical resistance and the resistance to stains of
agglomerated stones (see EN 14618) with polished surface after a prolonged contact with chemical materials.
NOTE It is reminded that the agglomerated stone containing calcium carbonate aggregates are sensitive to any acid
attack.
2 Normative references
The following referenced documents are indispensable for the application of this document. For dated references,
only the edition cited applies. For undated references, the latest edition of the referenced document (including any
amendments) applies.
Not applicable.
3 Principle
The resistance to a chemical attack is the characteristic which defines the behaviour of a floor/wall covering
material in contact with chemically aggressive agents, that is potentially able, to react with the surface itself,
corroding it, penetrating it permanently or anyway altering the visible aspect.
The deteriorating action of the chemical aggressive can generate two different effects:
− 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;
− a physical absorbing action, in accordance to which the aggressive agent is able to penetrate the surface, so
that the removal is extremely difficult or not possible.
Both these actions can involve a modification of the visible appearance of the surface of the chemical attacked
material, but only in the first case the damage can introduce also a modification in the physical and mechanical
properties of the material itself.
4 Determination of the chemical resistance
4.1 Chemical reagents
4.1.1 Water solution containing hydrochloric acid solution, 50 % (V/V), prepared from N hydrochloric acid
solution;
4.1.2 Sodium hydroxide in a 50 % (V/V) water solution, prepared from a normal water sodium hydroxide not
carbonated solution
4.2 Apparatus
Glossmeter able to measure with accuracy and precision of 10% the brightness degree of the surface.
The glossmeter shall measure the reflection of a light ray incident on a surface; the reflection degree is given by the
amount of light specularly reflected in a point of the surface with relationship to the amount of light reflected by the
standard glass plate. A light source representing the average daylight shall be used, such as the source CIE D 65,
with the lighting intensity allowed by the glossmeter calibration.
The glossmeter shall, at least, be equipped with two optical systems placed at 60° and 20° angles.It allows an
efficient measurement of the different reflection directions as the 60° angle covers a range of reflection degrees
from low to high, while the 20° angle allows to measure with greater accuracy the higher reflection directions (see
Annex A).
4.3 Preparation of the specimens
For each type of material to be tested four samples shall be prepared, with polished surface (at least 70
