8、-,- 111 4853903 Ob38778 851 E IS0 10545-12:1995( E) Foreword IS0 (the International Organization for Standardization) is a worldwide federation of national standards bodies (IS0 member bodies). The work of preparing International Standards is normally carried out through IS0 technical committees. Ea
9、ch member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. IS0 collaborates closely with the Internatio
10、nal Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies
11、 casting a vote. International Standard IS0 10545-1 2 was prepared by Technical Com- mittee ISOTTC 189, Ceramic tile. IS0 10545 consists of the following parts, under the general title Ceramic tiles: - Part i: Sampling and basis for acceptance - Part 2: Determination of dimensions and surface qualit
12、y - Part 3: Determination of water absorption, apparent porosity, appar- ent relative density and bulk density - Part 4: Determination of modulus of rupture and breaking strength - Part 5: Determination of impact resistance by measurement of co- efficient of restitution - Part 6: Determination of re
13、sistance to deep abrasion for unglazed tiles - Part 7: Determination of resistance to surface abrasion for glazed tiles - Part 8: Determination of linear thermal expansion O IS0 1995 All rights reserved.

19、f all ceramic tiles in- tended for use in freezing conditions in the presence of water. 2 Principle After impregnation with water, submission of the tiles to a cycle between + 5 “C and - 5 O C , all the sides of the tiles being exposed to freezing during a mini- mum of 100 freeze-thaw cycles. 3 Appa
20、ratus and materials 3.1 Drying oven, capable of being operated at Microwave, infrared or other drying systems may be used provided that it has been determined that the same results are obtained. (110 $_ 5) “C. 3.2 Balance, accurate to 0,Ol % of the mass of a test specimen. 3.3 Apparatus for impregna
21、tion with water after evacuation, by means of a vacuum pump capable of lowering the air pressure by (60 f 4) kPa in a tank containing the tiles. 3.4 Freezer, capable of freezing at least 10 tiles having a minimum total surface area of 0,25 m*, sup- ported in such a manner that the tiles shall be sep
22、ar- ated. 3.5 Chamois leather. 3.6 Water, maintained at a temperature of (20 f 5) “C. 3.7 Thermocouple, or another suitable temperature measuring device. 4 Test specimens 4.1 Sample A minimum area of 0.25 m2 and not less than 10 whole tiles shall be used. The tiles shall be free from defects. Releva
23、nt defects are cracks, crazing, holes, nipped edges and nipped corners. If tiles with defects have to be tested, the defects shall be marked with a permanent stain prior to the test and these defects shall be examined after test- ing. 4.2 Preparation o f test specimens The tiles shall be dried in th
24、e oven (3.1) adjusted to (1 10 f 5) O C , until constant mass is reached, .e. until the difference between two successive weighings at intervals of 24 h is less than 0,Ol Y. The dry mass of each tile (m,) shall be recorded. 5 Impregnation with water 5.1 After cooling to ambient temperature, place th
25、e tiles vertically in the dry vacuum tank (3.3) with no contact between them and no contact with the vac- uum tank. 1 Copyright International Organization for Standardization Provided by IHS under license with ISO Licensee=NASA Technical Standards 1/9972545001 Not for Resale, 04/27/2007 03:14:00 MDT

27、ntaining this pressure and cover the tiles with at least 50 mm head of water. Maintain the evacuation at the same pressure for a further 15 min and then restore atmospheric press- ure. Prepare the chamois leather (3.5) by wetting and wringing out by hand. Place it on a flat surface and lightly dry e
28、ach side of each tile in turn. Dab any relief surfaces with the chamois leather. Record the wet mass of each tile (e). 5.2 The initial water absorption, E, expressed as a percentage by mass, is calculated using the equation m2-m1 XI00 ml Ei = where ml is the mass of each dry tile; is the mass of eac
29、h wet tile. 6 Procedure Select one of the thickest tiles that is under test. It shall be one that is considered to have representative properties of that test sample. Drill a 3 mm diameter hole from the centre of one edge to a maximum dis- tance of 40 mm from the edge of the tile. Insert a thermocou
30、ple (3.7) and seal the hole with a piece of thermally insulating material (for example expanded polystyrene). If it is not possible to drill a hole in this way, place a thermocouple on the centre of one face of a tile and stick a second tile over this. Place all the tiles under test vertically in th
31、e freezer (3.4), sup- ported in such a way that there is a space between each one and an air flow over all the surfaces. Place the tile with the thermocouple in the middle of the test samples. The temperature of the thermocouple defines the temperature of all the tiles under test. Only in the case o
32、f repeated tests with similar test specimens can this be omitted, and then occasional checks shall be made with a thermocouple in a tile. All temperature measurements shall be accurate to f 0,5 “C. Lower the tile temperature to - 5 “C at a rate not ex- ceeding 20 “C/h. Maintain the tile temperature
33、below - 5 “C for 15 min. Immerse the tile in or spray it with water (3.6) until a tile temperature above + 5 “C is reached. Maintain the tile temperature above + 5 “C for 15 min. Repeat the cycle a minimum of 100 times. Interruption of the cycles shall be permitted only if the tiles are kept submerg
34、ed in water above + 5 “C. Weigh the tiles after the test (%) and then dry them to constant mass (m4). The final water absorption, 4, expressed as a percentage by mass, is calculated using the equation E2 = x100 m4 where m, m4 is the mass of each wet tile after the test; is the mass of each dry tile
35、after the test. After 100 cycles, examine the glazed or proper sur- faces and the edges of the tiles with the naked eye or with spectacles if usually worn, at a distance of 25 cm to 30 cm with an illumination of approximately 300 Ix. They may be examined at intermediate stages to expedite the report
36、ing, if there is reason to believe that they might sustain damage relatively early in the test. Record all damage that is observed on the glazed or proper surfaces and the edges of the tiles. 7 Test report The test report shall include the following information: reference to this part of IS0 10545;
37、an identification of the tiles, including any surface relief, if necessary; the number of test specimens in the sample; the initial water absorption, E,; the final water absorption, E2; a description of defects before the test and all damage on the glazed or proper surfaces and the edges of the tile
38、s after the freeze-thaw test; the number of damaged tiles after 100 cycles. 2 Copyright International Organization for Standardization Provided by IHS under license with ISO Licensee=NASA Technical Standards 1/9972545001 Not for Resale, 04/27/2007 03:14:00 MDTNo reproduction or networking permitted
