35、re of (55 5) C.5.1.2 Weak cleaning agent (a commercial agent), not containing abrasive, with a pH of 6,5 to 7,5.5.1.3 Strong cleaning agent (a commercial cleaning agent), containing abrasive, with a pH of 9 to 10. The cleaning agents used shall not contain hydrofluoric acid or its compounds.5.1.4 Su
36、itable solvents5.1.4.1 Hydrochloric acid solution, 3 % (v/v), prepared from concentrated hydrochloric acid ( = 1,19 g/ml) (see Annex C for preparation of the solution).5.1.4.2 Potassium hydroxide, 200 g/l solution. (see Annex C for preparation of the solution).5.1.4.3 Acetone.If other specific solve
37、nts are used, they shall be specified in the test report.5.2 Cleaning procedures and apparatus5.2.1 Procedure AClean the test specimen with running hot water (5.1.1) for 5 min, then wipe the surface with a damp cloth.5.2.2 Procedure BClean the test specimen manually with the weak cleaning agent (5.1
38、.2), using a natural, non-abrasive sponge or a cloth, then rinse the surface with running water, and finally wipe it with a damp cloth.5.2.3 Procedure CClean the test specimen mechanically with the strong cleaning agent (5.1.3). Example of apparatus includes rotating brush, with hard bristles, havin
39、g an 8 cm diameter, rotational frequency approximately 500 r/min, and tank for the cleaning agent, equipped with a suitable feeder and connected to the brush.Carry out cleaning for 2 min, then rinse the surface with running water and finally wipe it with a damp cloth.5.2.4 Procedure DImmerse the tes
40、t specimen for 24 h in a suitable solvent (5.1.4), then thoroughly rinse the surface with running water and finally wipe it with a damp cloth.All solvent should be used to remove the stain and should be tested successively. The use of the solvents will not obey a pre-established order.Cleaning is co
41、nsidered to be accomplished if any one of the solvents (5.1.4) removes the stain.2 ISO 2015 All rights reservedBS EN ISO 10545-14:2015ISO 10545-14:2015(E)5.3 Auxiliary apparatus5.3.1 Drying oven, capable of being operated at (105 5) C.Microwave, infrared, or other drying systems which allow shorter
42、drying times, may be used provided that it has been determined that the same results are obtained.6 Test specimensFive unused and undamaged test specimens shall be used, and they shall consist of whole tiles or cut tiles.For ceramic tiles that have some surface treatment, it should be tested upon ag
43、reement by the parties concerned.However, a sufficient surface area is required to ensure separation of the stains. If the tiles are too small, additional ones may be used. Do not use test specimens with surface defects. Thoroughly clean the surface with a suitable solvent, for example, ethanol. Dry
44、 each test specimens in the drying oven (5.3) maintained over (105 5) C during at least 2 h, and then, cool them until they reach room temperature. Test specimens shall be tested not later than 3 h after they have reached room temperature.If it is agreed to test tiles after abrasion (glazed and ungl
45、azed tiles), the samples shall be prepared according to the procedure specified in ISO 10545-7.The abrasion stage (cycles or revolutions) should be agreed by the parties concerned.7 Procedure7.1 Application of the staining agentSpread three or four drops of the paste (4.1.1 or 4.1.2) on the proper s
46、urface. Allow three or four drops of each of the liquids (4.2.1 and 4.3.1) to cover separate areas of the test surface. Place a convex watch glass with a diameter of approximately 30 mm (convex side down) on the applied drops, in order to spread them to an approximately circular area. Leave staining
47、 agents and the watch glass in place for 24 h.7.2 Attempts to remove stainsSubject the test specimens, treated according to 7.1, successively to the cleaning procedures described in 5.2 (procedures A, B, C, and D).After each cleaning procedure, dry the test specimens in the oven maintained over (105
48、 5) C during at least 2 h and subject them to a visual examination. Examine the surface with the naked eye or with spectacles, if usually worn, at a distance of 25 cm to 30 cm in artificial illumination minimum of 300 Ix.In the case of stains listed in 4.1, staining shall only be reported when the p
49、igment is visible. If there is no visible effect, i.e. if the stain has been removed, record the cleanability class according to Figure 1; if the stain is not removed, proceed to the following cleaning procedure.8 Classification of resultsIn consequence of the procedure described in 7.1 and 7.2, ceramic surfaces are divided into five classes given in Figure 1.Record the result for each test specimen (unabraded and, if agreed, after abrasion) with each staining agent.Class 5 corresponds to the greatest ease of removing the parti
