5.1.1.1 Apparatus The tests are made with a measuring apparatus with a precision of at least 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 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 declared by the manufacturer shall be calculated and noted in the test report.

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 5.1.2.2 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. SIST EN 1024:2012

EN 1024:2012 (E) 7 5.1.2.4 Procedure The tiles are laid upside down in two rows on a flat surface, and interlocked 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, the 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, transversely in order to obtain the values l1 and 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 Expression of results The mean cover length (L) is obtained from the following formula: L
