Limits are given in Table 2. The squareness of rectangular glass panes is expressed by the difference between their 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.

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. There are six kinds of distortion: — overall bow (see Figure 3); — roller wave distortion (for horizontally toughened glass only) (see Figure 4); — air cushion wave distortion (for air cushion toughened glass only); — edge lift (for horizontally toughened glass only) (see Figure 5); — perimeter deformation (for toughened glass manufactured by air cushion process) (see Figure 10); NOTE 1 Overall bow, roller wave, edge lift and perimeter deformation can, in general, be accommodated by the framing system. — local distortion (for vertically toughened glass only) (see Figure 6).
