27、, each of which constitutes a whole tile, except for the measurement of cover dimensions, which requires 24 tiles. 5 Tests methods 5.1 Determination of dimensional characteristics 5.1.1 Individual dimensions1)5.1.1.1 Apparatus The tests are made with a measuring apparatus with a precision of at leas

28、t one millimetre. 5.1.1.2 Procedure After removing any surplus clay from the edges, the measurements shall be taken, both transversely and longitudinally along the centre of the tile unless another measuring position has been specified by the manufacturer (see Figure 1). The dimensions are expressed

29、 to the nearest whole millimetre. Key 1 tile Figure 1 Principle for measuring individual dimensions 5.1.1.3 Expression of results The arithmetic means of the lengths and widths of the 10 tested tiles and the differences expressed as a percentage of these mean values in relation to the values A and B

30、 declared by the manufacturer shall be calculated and noted in the test report. 1) EN 1304 specifies to which type of tiles these measurements apply. DIN EN 1024:2012-06 EN 1024:2012 (E) 6 5.1.2 Overlap dimensions (margins)1)5.1.2.1 Principle The mean overlap dimensions are determined longitudinally

31、 and transversely. They are measured as indicated in Figure 2. NOTE Certain tile models can only be measured in one direction. Key 1 mean cover length 1.1 open position 1.2 closed position 2 mean cover width 2.1 open position 2.2 closed position Figure 2 Principle for measuring cover dimensions 5.1.

32、2.2 Number of test pieces 24 tiles are required for the measurements. 5.1.2.3 Apparatus The tests are carried out with a measuring apparatus with a precision of at least 1 mm. DIN EN 1024:2012-06 EN 1024:2012 (E) 7 5.1.2.4 Procedure The tiles are laid upside down in two rows on a flat surface, and i

33、nterlocked with one another so as to form a stable unit. Certain types of tiles may require laying the right way up. The tiles are interlocked longitudinally and pulled apart individually to measure the maximum distance between two corresponding points on the first and the eleventh tile, i.e. L1, th

34、e maximum length. Following this, the tiles are taken up, then relaid and interlocked. They are pushed together individually as closely as possible to carry out the measurement of the minimum distance (L2) following the procedure described above. Take again the same measurements, but this time, tran

35、sversely in order to obtain the values l1and l2. With regard to tiles with a variable overlap, determine only the measurement of cover in the open position, L1(longitudinally), l1(transversely). NOTE This method is not relevant to some types of tiles designed to be laid broken jointed. 5.1.2.5 Expre

36、ssion of results The mean cover length (L) is obtained from the following formula: L = (L1+L2) / 20 (1) The maximum cover length (LM) (tiles with a variable overlap) is obtained from the following formula: LM= L1/ 10 (2) The mean cover width (l) is calculated from the following formula: l = (l1 + l2

37、) / 20 (3) The maximum cover width (lM) (of tiles with a variable overlap) is calculated from the following formula: lM= l1/ 10 (4) The calculated values as recorded are rounded to the nearest whole millimetre. The percentage difference of these cover dimensions compared with those declared by the m

38、anufacturer are calculated and stated in the test report. 5.2 Cambers 5.2.1 Principle Measure height of camber longitudinally and transversely for plain tiles (see Figures 3, 4 and 5) and longitudinally only for all other types of tile (see Figures 6, 7 and 8). The height of camber for a curvature w

39、hose concavity is located on the outer surface of the tile are given a minus sign and a plus sign is given in the opposite case. The measurement is taken to a precision of at least 0,5 mm on each outside edge of the tile, with the most unfavourable value being selected. Take as measurement bases LAa

40、nd LBequal to2/3 of the total length (LT) and width (lT) of the tile. Where this is not possible, the measurement base may be reduced to the largest dimension that is compatible with the shape of the tile.

44、 combined with a device to measure the height of camber accurately to a precision of at least 0,5 mm. Key 1 dial gauge 2 rule 3 contact points Figure 9 Apparatus for measuring cambers The two outer contact points on the rule shall be able to slide so as to adjust to different measurement lengths. An

46、.2.3.1.2 Tiles with sidelock and headlock, and tiles with sidelock only The measurement is taken on the outer surface of the tile in the bottom of the interlock groove, as well as on the lower edge of the flange which locks into this groove. 5.2.3.1.3 Over-and-under tiles This measurement is taken a

47、long the axis in the bottom of the concavity of the tile, or for tiles with a flat bottom, along the centre line. 5.2.3.2 Transverse measurement - Plain tiles The measurement is taken on the exterior face of the tile along the two transverse - upper and lower - outer edges. (For tiles whose lower ed

48、ge is not a straight line, take the measurement at the widest point of the tile, as far as possible towards the lower edge).
