NOTE The information is given in Annex A. 3.2 edge deformation deformation of the edge because of the tong marks 3.3 edge lift (also referred to as edge dip) distortion produced in horizontal toughened glass, at the leading and trailing edge of the plate NOTE This is a distortion produced by a reduction in surface flatness.

The fragmentation described in Clause 8 is undertaken on unrestrained test specimens. The fragmentation in service may not always correspond to that determined during the fragmentation test due to the imposition of other stresses, i.e. from fixing or from reprocessing (e.g. laminating). 6 Dimensions and tolerances
6.1 Nominal thickness and thickness tolerances The nominal thicknesses and thickness tolerances are those given in the relevant product standard (see Clause 4), some of which are reproduced in Table 1.

The thickness of a pane shall be determined as for the basic product. The measurement shall be taken at the centres of the 4 sides, and away from the area of any tong marks (see Figure 2), which may be present. SIST EN 13024-1:2012

Limits are given in Table 2. The squareness of rectangular glass panes is expressed by the difference between its diagonals.
The difference between the two diagonal lengths of the pane of glass shall not be larger than the deviation limit v as specified in Table 3. The limits of squareness are described by deviation between diagonals. Limits are given in Table 3.

6.2.4 Edge deformation produced by the vertical process The tongs used to suspend the glass during toughening result in surface depressions, known as tong marks (see Figure 2). The centres of the tong marks are situated up to a maximum of 20 mm in from the edge. A deformation of the edge less than 2 mm can be produced in the region of the tong mark and there may also be an area of optical distortion. These deformations are included in the tolerances in Table 2.

This difference in flatness depends on the type of glass, e.g. coated etc., glass dimensions, i.e. the nominal thickness, the dimensions and the ratio between the dimensions, and the toughening process employed, i.e. vertical or horizontal. There are four kinds of distortion:  overall bow (see Fi
