International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Co

20、mmission (IEC) on all matters of electrotechnical standardization.The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents

37、ile under test.7.3 Preparation of test specimensThoroughly clean the surface with a suitable solvent, for example, ethanol. Do not use test specimens with surface defects.8 Procedure8.1 Application of test solutionsDry each test specimens in the drying oven (6.3) maintained over 105 C 5 C during at

38、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.Apply a uniform layer of the sealing material (6.6) 3 mm thick to the rim of the cylinder (6.2). Turn the cylinder upside down onto a fresh part

39、of the proper surface and seal around the rim. Pour the test solution through the inlet to a height of (20 1) mm.If it is not practical to maintain a constant level of solution, immerse the test specimens vertically to a depth of 25 mm in the vessel (6.1) containing the test solution. Cover with the

40、 lid (6.1).The test solution shall be all of those listed in 5.1, 5.2 and 5.3.1; if required, the test solutions listed in 5.3.2 may be used.Maintain the test assembly at (20 5) C.For testing the resistance to household chemicals, swimming pool salts and citric acid, maintain the test solutions in c

41、ontact with the test specimen for 24 h. Remove the cylinder and clean the proper surface with a suitable solvent to completely remove the sealing material. When the procedure by partial immersion is used, maintain the test solutions in contact with the test specimens for 24 h, then remove the test s

42、pecimens.For testing the resistance to hydrochloric acid, lactic acid and potassium hydroxide, maintain the test solution in contact with the test specimen for a total of (96 + 1) h. Ensure that the level of the test solution does not change. Replace the test solution after (48 + 1) h. After more (4

43、8 + 1) h, remove the cylinder and clean the surface with a suitable solvent to completely remove the sealing material.When the procedure by partial immersion is followed, maintain the test solutions in contact with the test specimens for (96 + 1) h, then remove the test specimens.Thoroughly rinse th

44、e specimens under running water for a period of 10 min to remove any residual testing solution. If needed, clean the surface with a soft bristle brush to remove test solutions.

46、he marks with a wet cloth (6.5).If the pencil marks cannot be removed, the classification system of Figure 1 is not applicable and these tiles shall be reported as “Normal classification not possible”. An alternative visual classification is provided for these tiles in 8.2.3.8.2.2 Normal classificat

47、ionFor tiles passing the pencil test, carry out the operations described in 8.2.2.1, 8.2.2.2 and 8.2.2.3 and apply the classification system indicated in Figure 1.8.2.2.1 Visual examinationExamine the proper surface that has been tested from all angles from a standard distance of 25 cm and under a m

After examination, if there is no visible

49、 effect, perform the pencil test described in 8.2.2.2. If there is a visible effect, perform the reflection test described in 8.2.2.3.8.2.2.2 Pencil testDraw several lines with the pencil (6.8) both on the surface under test and on the untreated surface. Attempt to remove the pencil lines with the wet cloth (6.5). If the pencil marks are removed from the treated surface, the surface corresponds to class A. If they are not removed, the surface corresponds to class B.8.2.2.3 Reflection testHold the tile so that the image of the
