28、deration of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that com
29、mittee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. Draft International Standards adopted by the
30、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 casting a vote. International Standard ISO 10545-5 was prepared by Technical Committee ISO/TC 189, Ceramic tile. ISO 10545 consists of
31、 the following parts, under the general title Ceramic tiles: Part 1: Sampling and basis for acceptance; Part 2: Determination of dimensions and surface quality; Part 3: Determination of water absorption, apparent porosity, apparent relative density and bulk density; Part 4: Determination of modulus
32、of rupture and breaking strength; Part 5: Determination of impact resistance by measurement of co-efficient of restitution; Part 6: Determination of resistance to deep abrasion for unglazed tiles; Part 7: Determination of resistance to surface abrasion for glazed tiles; Part 8: Determination of line

36、tiles by measuring the coefficient of restitution. 2 Definition For the purpose of this part of ISO 10545, the following definition applies. 2.1 coefficient of restitution between two impacting bodies, e relative velocity of departure divided by the relative velocity of approach 3 Principle Determin
37、ation of the coefficient of restitution by dropping a steel ball from a fixed height onto the test specimen and measuring the height of rebound. 4 Apparatus 4.1 Chrome steel ball, of diameter (19 0,05) mm. 4.2 Ball-release apparatus, (see Figure 1), consisting of a heavy steel base set on levelling
38、screws with a vertical steel bar to which is attached an electromagnet, a guide tube and a test unit support. The test unit is clamped firmly in a position so that when the steel ball drops it impinges on the centre of the horizontal tile surface. A clamping device is shown in Figure 1, but any suit
39、able system may be used. 4.3 Electronic timing device (optional), which, by means of a microphone, measures the time interval between the first and second impacts when the ball is dropped onto the test specimen. 5 Test specimens 5.1 Number of test specimens A minimum of five pieces in dimensions 75
40、mm 75 mm cut from five tiles. Tiles with facial dimensions less than 75 mm may be used. 5.2 Brief description of test units The test units consist of test specimens fixed to mature concrete blocks by means of rigid epoxide resin adhesive. 5.3 Concrete blocks The dense concrete blocks shall be of app
41、roximate dimensions 75 mm 75 mm 50 mm and prepared in moulds of this size, or alternatively cut from large concrete slabs. The following method describes the preparation of dense concrete blocks made from gravel/sand, but other aggregates may be used and then the surface water absorption test may no
42、t be appropriate. Concrete blocks or slabs may be made by adding one part by mass of Portland cement to 4.5 to 5.5 parts by mass of aggregate. The aggregate shall be gravel sand of 0 to 8 mm particle size with a continuous grading curve between the limits A and B in Figure 2. The total fines of part
43、icle size below 0,125 mm in the mix of concrete, including Portland cement, should be about 500 kg per cubic metre. The water/cement ratio shall be 0,5. Thoroughly mix the constituents in a mechanical mixer and trowel into moulds of the required size. Compact for 90 s at 50 Hz on a vibrating table.
44、Condition the concrete slabs for 48 h at (23 2) C and (50 5) % relative humidity before removing them from the moulds. Thoroughly rinse off any mould release agent. Throughout the remaining conditioning, the slabs shall be held vertically, leaving gaps between them. Immerse in water at (20 2) C for
45、6 d, then in air at (23 2) C and (50 5) % relative humidity for 21 d. The assembly face of the concrete shall have an absorption of surface water after 4 h in the range of 0,5 cm3 to 1,5 cm3 when three specimens are tested in accordance with the method shown in Annex A and Figure A.1. Blocks subsequ
46、ently cut from concrete slabs by wet methods require a minimum drying period of 24 h at (23 2) C and (50 5) % relative humidity before assembly in test units. 5.4 Epoxide resin adhesive The adhesive shall not contain ingredients which increase flexibility. A suitable adhesive consists of 2 parts by
47、mass of an epoxide resin, which is a reaction product of epichlorhydrin and diphenol isopropane and one part by mass of a curing agent which is an activated amine. Pure silica filler of average particle size 5,5 4m, measured by the Coulter Counter or other similar methods, is thoroughly mixed with t
48、he other constituents in a proportion which is just sufficient to form a mixture that does not flow.
