BS EN 14617-10:2012EN 14617-10:2012 (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 su
22、rface after a prolonged contact with chemical materials. NOTE It is to be remembered that agglomerated stones 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
23、 are indispensable for its application. 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 Resistance to a chemical attack is the characteristic which defines the
24、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 gene
25、rate 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, according to which the aggressive agent is able to penetrate the
26、 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
27、 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
28、 sodium hydroxide non-carbonated solution. 4.2 Apparatus Glossmeter, able to measure with an 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 s
29、pecularly reflected in a point of the surface in relationship to the amount of light BS EN 14617-10:2012EN 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 gl
30、ossmeter calibration. The glossmeter shall be equipped with at least two optical systems placed at 60 and 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 a
31、ccuracy to the measurement of 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 a polished surface2of at least 300 mm 300 mm onto which a containing ring (at least 100 mm diameter) is glued. The
32、 ring is made of chemically resistant material such as silicone. The surface to be measured shall be flat 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 treatme
33、nt layers using ketone or another appropriate solvent. 4.4 Test procedure The procedure consists of positioning 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
34、 surface. The test shall be carried out at an ambient temperature of (23 5) C. On each of the four specimens, 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
35、 within the ring, pour 10 ml to 15 ml of hydrochloric acid solution (4.1.1), avoiding any possible overflowing. 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
36、for the test. After 1 h 5 min draw out one specimen containing hydrochloric acid and one containing sodium 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 w
37、ashing and drying procedure. Repeat the reflection measurement on at least in 5 points on each of the four 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 inci
38、dent light positioned at 60. 4.5 Expression of the results a) The effects of the chemical attack are expressed 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 aci
39、ds and alkali shall be attributed as follows: 1Commission Internationale de lEclairage (Central Bureau, Kagelpasse 27, A-1030 Vienna-AT). 2Obtained by polishing with abrasive grit, grain size F500, according to ISO 8486-2:2007, Bonded abrasives Determination and designation of grain size distributio

41、and 80 % of the reflection reference value after 8 h 30 min of acid and basic attack; C2: materials, which keep between 60 % and 80 % of the reflection reference value after 1 h 30 min of acid and basic attack; C1: materials, which keep less than 60 % of the reflection reference values after 1 h 30
42、min of basic and acid attack. b) The values are calculated on the basis of 5 measurements and the dispersion is declared. 4.6 Test report The test report shall contain the following information: a) unique identification number of the report; b) number and year of issue of this European Standard, i.e

48、 Determination of the resistance to stains A.1 Principle This test is a reference method used to determine the potential damage caused by staining agents that could reasonably enter into contact with the surface of a material. The stain effect is dependent on the viscosity of the fluid that could en
49、ter the part of the material under test. At the least, substances of common use shall be poured onto the surface to evaluate the generic resistance to stains of agglomerated stones. A.2 Staining agent The staining agent shall be chosen among the substances proposed by the client or selected through agreement between the interested parties. A.3 Preparation of the specimens The specimens shall have dimensions of 70 mm 70 mm and a flat
