    24、17-10:2012 (E) 4 1 Scope This European Standard specifies a method for determining the chemical resistance and the resistance to stains of agglomerated stones (see EN 14618) with a polished surface after a prolonged contact with chemical materials. NOTE It is to be remembered that agglomerated stone

    25、s containing calcium carbonate aggregates are sensitive to any acid attack. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated re

    26、ferences, the latest edition of the referenced document (including any amendments) applies. Not applicable. 3 Principle 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

    27、 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: a real chemical action, according to which the alteration of the surface is due

    28、to the chemical reaction between the aggressive agent and some constituents of the surface itself; 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 m

    29、odification 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. 4 Determination of the chemical resistance 4.1 Chemical reagents 4.1.1 W

    30、ater 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 non-carbonated solution. 4.2 Apparatus Glossmeter, able to measure with an accuracy and pr

    31、ecision 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 in relationship to the amount of light DIN EN 14617-10:2012-06

    32、 EN 14617-10:2012 (E) 5 reflected by the standard glass plate. A light source representing average daylight shall be used, such as the source CIE1D 65, with the lighting intensity allowed by the glossmeter calibration. The glossmeter shall be equipped with at least two optical systems placed at 60 a

    33、nd 20 angles. This allows for an efficient measurement of the different reflection directions: the 60 angle covers a range of reflection degrees from low to high, while the 20 angle lends greater accuracy to the measurement of the higher reflection directions (see Annex A). 4.3 Preparation of the sp

    34、ecimens For each type of material to be tested four samples shall be prepared with a polished surface2of at least 300 mm 300 mm onto which a containing ring (at least 100 mm diameter) is glued. The ring is made of chemically resistant material such as silicone. The surface to be measured shall be fl

    35、at in order to permit the positioning of the instrument sensor in contact with the material to be tested. Before testing, the surface shall be cleaned of any possible wax, other finishes or treatment layers using ketone or another appropriate solvent. 4.4 Test procedure The procedure consists of pos

    36、itioning the instrument sensor in contact with the surface to be measured, and of reading the number reported on the display which defines the reflection degree as a reference value of the examined surface. The test shall be carried out at an ambient temperature of (23 5) C. On each of the four spec

    37、imens, it is necessary to carry out the reflection measurement on at least five different points, and to then calculate the average value (M1) of each specimen. On two specimens placed horizontally within the ring, pour 10 ml to 15 ml of hydrochloric acid solution (4.1.1), avoiding any possible over

    38、flowing. Repeat this operation on the other two specimens using the sodium hydroxide solution (4.1.2). Keep the specimens, protected with a polyethylene film, on a table for all the time requested for the test. After 1 h 5 min draw out one specimen containing hydrochloric acid and one containing sod

    39、ium hydroxide respectively; wash them carefully with water and remove the ring. Finally, dry them with soft cellulose paper. After 8 h 30 min draw out the two other specimens and perform the same washing and drying procedure. Repeat the reflection measurement on at least in 5 points on each of the f

    40、our specimens, and then calculate the average value for each specimen and the standard deviation of the 5 values. The reflection measurements are to be carried out with the glossmeter under an incident light positioned at 60. 4.5 Expression of the results a) The effects of the chemical attack are ex

    41、pressed as the loss of the reference reflection value. This loss is calculated as a percentage of reflection of the material tested with respect to the reference value. A class of resistance to acids and alkali shall be attributed as follows: 1Commission Internationale de lEclairage (Central Bureau,
