4.7 Dimensional tolerances of curved laminated glass
4.7.1 Thickness
The total thickness of the laminated glass shall equal the sum of the nominal thickness of the components. The tolerance in the total thickness shall equal the sum of the tolerances on the components given in the relevant product standard.
Thicknesses and tolerances on the interlayer and films shall be negligible when compared to the shape tolerances of the individual glass panes.
The accepted thickness tolerance of the interlayer in cast-in-place resins shall be ± 0.2 mm per mm thickness of the interlayer (not including the thickness tolerance of the individual panes).
4.7.2 Displacement
The maximum displacement in the sliding “ii” of one of the glass edges, as shown in Figure 5, during the manufacturing of the curved laminated glass, shall be as given in Table 5, where G is the girth of the curved insulating glass unit.
