EN 14617-10:2005 (E) 4 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. N
23、OTE 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
24、 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 pot
25、entially 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
26、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 modi
27、fication 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
28、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
29、 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 ? EN 14617-10:20
30、05 (E) 5 standard glass plate. A light source representing the average daylight shall be used, such as the source CIE1 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
31、 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 t
32、o be tested four samples shall be prepared, with polished surface2 (at least 70 mm x 70 mm) on which a containing ring (40 mm - 50 mm diameter) is glued. The ring is made by chemically resistant material, for example silicone. The surface to be measured shall be flat in order to permit the positioni
33、ng of the instrument sensor in contact with the material to be tested. Before testing the surface under test shall be cleaned from any possible wax or finishes treatment layers by ketone or other appropriate solvents. 4.4 Test procedure The procedure consists of positioning the instrument sensor as
34、much as possible in contact with the surface to be measured and of reading the number reported on the display which defines the reflection degree as reference value of the examined surface. The test is carried out at ambient temperature (23 5)C. On each of the four specimens is necessary to carry ou
35、t the reflection measurement at least in five different points and calculate the average value (M1) of each specimen. On two specimens placed horizontally within the ring, pour 4 or 5 milliliters of hydrochloric acid solution (4.1.1), avoiding possible overflowing. Repeat this operation on other two
36、 specimens using 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 hour 5 minutes draw one specimen containing hydrochloric acid and one containing sodium hydroxide respectively, wash them carefully
37、with water and also remove the ring; at the end dry them with soft cellulose paper. After 8 hours 30 minutes draw the two other specimens and carry out the same washing and drying procedure. Repeat the reflection measurement on the four specimens at least in 5 points and calculate the average value
38、for each specimen and the standard deviation of the 5 values: the reflection measurements are carried out with the glossmeter under incident light at 60. 4.5 Expression of the results a) The effects of the chemical attack are expressed as loss of the reference reflection value. This loss is calculat
39、ed as 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: 1 Commission Internationale de l Eclairage (Central Bureau, Kagelpasse 27, A-1030 Vienna-AT) 2 Obtained by polishing with abrasive grit
40、 grain size F500 according to ISO 8486-2, Bonded abrasives Determination and designation of grain size distribution: Part 2: monogrits F230 to F1200 (1996). ? EN 14617-10:2005 (E) 6 C4: materials, which keep at least 80% of the reflection reference value after 8 h 30 minutes of acid or basic attack
41、(or if only in one specimen the attack is between 60% and 80%); C3: materials, which keep between 60% and 80% of the reflection reference value after 8 h 30 minutes of acid attack and 1 h 5 minutes of basic attack; C2: materials, which keep between 60% and 80% of the reflection reference value after
42、 8 h 30 minutes of basic attack and 1 h 5 minutes of acid attack; C1: materials, which keep less than 60% of the reflection reference values (after 8 h 30 minutes of basic or acid attack). b) The values are calculated on the basis of 5 measurement and the dispersion declared. 4.6 Test report The tes

EN 14617-10:2005 (E) 8 Annex A (informative) 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 which could reasonably enter in contact with the surface
49、of a material. The stain effect is depending from the viscosity of the fluid that could enter the part of the material under test. At least substances of common use must be poured on a surface to evaluate a generic resistance to stains of an agglomerated stone. A.2 Staining agent The staining agent shall be chosen among the su
