It is technically equivalent to ISO10545-2:1995, including its Technical Corrigendum1:1997, published by the International Organization for Standardization (ISO)

10、. It supersedes BS6431-10:1984, which will be withdrawn when Parts1 to16 of BSENISO10545 have all been published. This Part of BSENISO10545 was originally drafted by CEN/TC67, Ceramic tiles, as EN98, published in1984, and confirmed in1991. Subsequently the European Standard was revised by ISO as a P

11、art of ISO10545, which has now been approved by CEN as a Part of ENISO10545. The editorial modifications mentioned in the ENISO foreword have been made in this BSENISO text. The technical changes from the method described in BS6431-10 are as follows. For the measurement of straightness of sides, rec

12、tangularity and surface flatness, a single diagrammatic figure replacesFigure 1 andFigure 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 not purport to include all the necessary

13、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.

30、3 1 Scope This part of ISO10545 specifies methods for determining the dimensional characteristics (length, width, thickness, straightness of sides, rectangularity, surface flatness) and the surface quality of ceramic tiles. Tiles with areas less than4cm 2are excluded from measurements of length, wid

31、th, 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, rectangularity, if these are subsequently hidden in the joints after fixing (installation). 2 Measur

32、ement 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 Measure, to the nearest0,1mm, each side of the tile under test, at positions5mm from the corners. 2

33、.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 of40measurements. For oblong tiles, each similar pair of sides of a tile provides the appropriate average dimension of the tile, i.e.an average of tw

34、o measurements. The average dimensions for length and width of the sample are the average of20measurements each. 2.5 Test report The test report shall include the following information: a) reference to this part of ISO10545; b) a description of the tiles; c) all individual measurements of length and

35、 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 the10test specimens for square tiles, and the average length and width for oblong tiles; f) the deviation, as a percentage, of the average size of each ti

36、le (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 the10test specimens (20 or40sides). 3 Measurement of thickness 3.1 Apparatus 3.1.1 Micrometer screw gauge with anvils, of5mm to10mm diameter, or

37、 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 between the corners and measure the thickness at the thickest point within each of the four segments. Measure, to the neare

38、st0,1mm, 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 of0,125; 0,375; 0,625 and0,875times the length measured from the end. Measure the thickness at the thickest point on each line. 3.4 Expressio

39、n 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 of40measurements. 3.5 Test report The test report shall include the following information: a) reference to this part of ISO10545; b) a

40、 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 required by the product standard), of the average thickness of each tile from the work size thickness. 4 Measurement of straightness

41、of sides 4.1 Definition For the purposes of this part of ISO10545, the following definition applies. 4.1.1 straightness of sides the deviation from straightness of the centre of the side in the plane of the tileENISO10545-2:1997 4 BSI 04-2000 the measurement is only relevant to the straight sides of

42、 tiles (Figure 2) and is calculated as a percentage, using the formula 4.2 Apparatus 4.2.1 Apparatus, as shown inFigure 1, or any other suitable instrument. The dial gauge (D F ) is used for measuring the straightness of sides. 4.2.2 Calibrating plate, of accurate dimensions and with straight, flat

43、sides. 4.3 Test specimens Ten whole tiles shall be submitted to 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 (S A , S B , S C ), the locating studs (I A , I B , I C ) are5mm from each cor

44、ner of the side being measured. (SeeFigure 1.) Fit the appropriate calibrating 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

45、, and record the dial gauge reading in the centre of the side. If the tile 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

46、 the nearest0,1mm. 4.5 Test report The test report shall include the following information: a) reference to this part of ISO10545; 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 correspond

47、ing work sizes. 5 Measurement of rectangularity 5.1 Definition For the purposes of this part of ISO10545, 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 (seeFigure 3), deviation from rectangular

48、ity is calculated as a percentage, using the formula 5.2 Apparatus 5.2.1 Apparatus, as shown inFigure 1, or any other suitable instrument. The dial gauge (D A ) is used for measuring rectangularity. 5.2.2 Calibrating plate, of accurate dimensions and with straight, flat sides. 5.3 Test specimens Ten

49、 whole tiles shall be submitted to measurements. 5.4 Procedure Select an apparatus of the appropriate dimensions(5.2.1) so that, when a tile is placed in the apparatus, on the supporting studs (S A , S B , S C ), the locating studs (I A , I S , I C ) are5mm from each corner of the side adjacent to the side being measured. (SeeFigure 1.) The plunger of the dial gauge (D A ) shall also be5mm from the corner of the tile on the side being measured. (SeeFigure 1.) Fit the appropriate calibrating plate (5.2.2) ex
