10、EN ISO 10545-2:1997 Ceramic tiles Part 2: Determination of dimensions and surface quality, published by the European Committee for Standardization (CEN). It is technically equivalent to ISO 10545-2:1995, including its Technical Corrigendum 1:1997, published by the International Organization for Stan
11、dardization (ISO). It supersedes BS 6431-10:1984, which will be withdrawn when Parts 1 to 16 of BS EN ISO 10545 have all been published. This Part of BS EN ISO 10545 was originally drafted by CEN/TC 67, Ceramic tiles, as EN 98, published in 1984, and confirmed in 1991. Subsequently the European Stan
12、dard was revised by ISO as a Part of ISO 10545, which has now been approved by CEN as a Part of EN ISO 10545. The editorial modifications mentioned in the EN ISO foreword have been made in this BS EN ISO text. The technical changes from the method described in BS 6431-10 are as follows. For the meas
13、urement of straightness of sides, rectangularity and surface flatness, a single diagrammatic figure replaces Figure 1 and Figure 2. The material of the calibrating plate for this measuring apparatus is not restricted to steel when measuring straightness and rectangularity. A British Standard does no
14、t purport to include all the necessary provisions of a contract. Users of British Standards are responsible for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations. Summary of pages This document comprises a front cover, an inside f

33、y of ceramic tiles. Tiles with areas less than 4 cm2 are excluded from measurements of length, width, straightness of sides, rectangularity and surface flatness. Spacer lugs and glaze blobs and other irregularities of the sides shall be ignored when measuring length, width, straightness of sides, re
34、ctangularity, if these are subsequently hidden in the joints after fixing (installation). 2 Measurement of length and width 2.1 Apparatus 2.1.1 Vernier calipers, or other suitable apparatus for linear measurement. 2.2 Test specimens Ten whole tiles shall be submitted to measurements. 2.3 Procedure M
35、easure, to the nearest 0,1 mm, each side of the tile under test, at positions 5 mm from the corners. 2.4 Expression of results The average dimension of square tiles is the average of four measurements. The average dimension of the sample is the average of 40 measurements. For oblong tiles, each simi
36、lar pair of sides of a tile provides the appropriate average dimension of the tile, i.e. an average of two measurements. The average dimensions for length and width of the sample are the average of 20 measurements each. 2.5 Test report The test report shall include the following information: a) refe
37、rence to this part of ISO 10545; b) a description of the tiles; c) all individual measurements of length and width; d) the average size of each test specimen for square tiles, and the average length and width for each oblong tile; e) the average size of the 10 test specimens for square tiles, and th
38、e average length and width for oblong tiles; f) the deviation, as a percentage, of the average size of each tile (two or four sides) from the work size; g) the deviation, as a percentage, of the average size of each tile (two or four sides) from the average size of the 10 test specimens (20 or 40 si
39、des). 3 Measurement of thickness 3.1 Apparatus 3.1.1 Micrometer screw gauge with anvils, of 5 mm to 10 mm diameter, or other suitable apparatus. 3.2 Test specimens Ten whole tiles shall be submitted to measurements. 3.3 Procedure For all tiles, except those with uneven surfaces, draw diagonals betwe
40、en the corners and measure the thickness at the thickest point within each of the four segments. Measure, to the nearest 0,1 mm, the thickness of each tile under test in four positions. For tiles with uneven surfaces, draw four lines at right angles across the face at distances of 0,125; 0,375; 0,62
41、5 and 0,875 times the length measured from the end. Measure the thickness at the thickest point on each line. 3.4 Expression of results For all the tiles, the average dimension of each individual tile is the average of four measurements. The average thickness of the sample is the average of 40 measu
42、rements. 3.5 Test report The test report shall include the following information: a) reference to this part of ISO 10545; b) a description of the tiles; c) all individual measurements of thickness; d) the average thickness of each tile; e) the deviation, as a percentage or in millimetres (as require
43、d by the product standard), of the average thickness of each tile from the work size thickness. 4 Measurement of straightness of sides 4.1 Definition For the purposes of this part of ISO 10545, the following definition applies. 4.1.1 straightness of sides the deviation from straightness of the centr
44、e of the side in the plane of the tile Licensed Copy: sheffieldun sheffieldun, na, Mon Nov 20 03:09:06 GMT+00:00 2006, Uncontrolled Copy, (c) BSI EN ISO 10545-2:1997 4 BSI 04-2000 the measurement is only relevant to the straight sides of tiles (Figure 2) and is calculated as a percentage, using the
45、formula 4.2 Apparatus 4.2.1 Apparatus, as shown in Figure 1, or any other suitable instrument. The dial gauge (DF) is used for measuring the straightness of sides. 4.2.2 Calibrating plate, of accurate dimensions and with straight, flat sides. 4.3 Test specimens Ten whole tiles shall be submitted to
46、measurements. 4.4 Procedure Select an apparatus of the appropriate dimensions (4.2.1) so that, when a tile is placed in the apparatus, on the supporting studs (SA, SB, SC), the locating studs (IA, IB, IC) are 5 mm from each corner of the side being measured. (See Figure 1.) Fit the appropriate calib
47、rating plate (4.2.2) exactly into position on the instrument, and adjust the dial gauge reading to a suitable known value. Remove the calibrating plate, place the proper surface of the tile on the locating studs in the apparatus, and record the dial gauge reading in the centre of the side. If the ti
48、le is square, rotate it to obtain four measurements. Repeat this procedure for each tile being tested. In the case of oblong tiles, use separate instruments of the appropriate dimensions to measure lengths and widths. Measure to the nearest 0,1 mm. 4.5 Test report The test report shall include the f
49、ollowing information: a) reference to this part of ISO 10545; b) a description of tiles; c) all individual measurements of straightness of sides; d) the maximum deviation from straightness, as a percentage related to the corresponding work sizes. 5 Measurement of rectangularity 5.1 Definition For the purposes of this part of ISO 10545, the following definition applies. 5.1.1 deviation from rectangularity if a corner of a tile is placed against the angle of an accurate calibrating plate (see Figure 3), devia
