The minimum dimensions of cut-to-size panels will be gladly supplied to you on request. The maximum dimensions of cut-to-size panels are equivalent to the minimum usable area of the stock sizes. Edge length l1, l2 Tolerance ≤ 500 mm ± 1.0 mm > 500 mm ± 1.5 mm Flatness (f) describes the maximum deviation from flatness for stock sizes and is tested with the aid of a straightedge and a feeler gauge. The following applies to stock sizes: Flatness ≤ 0.3% x measured length. Measured length at least 500 mm. 2.1.1 Flatness Standard length tolerance cut-to-size panels, standard form cut-to-size panels Flatness (f) describes the maximum deviation from flatness and is tested with the aid of a straightedge and a feeler gauge. Maximum deflection for cut-tosize panels: Flatness ≤ 0.3% x diagonal of the cut-to-size panel. The limits shown in the sketch below apply to the squareness of the panels: 2.2.1 Flatness 2.2.2 Squareness Squareness tolerance Edge length Tolerance ≤ 500 mm a ≤ 1.0 mm > 500 mm a ≤ 1.5 mm Tolerance area a is the range within which the actual dimensions of the panel vary.

ROBAX® curved and angular bent panels are available in various versions in 3, 4 and 5 mm thicknesses. If you need a custom-tailored solution, please enquire early about our available models and shapes. This helps us reduce delivery times and costs. For curved panels, we recommend selecting radii in increments of 10 (200, 210, 220, etc.) or in increments of 20 (600, 620, 640, etc.) for a radius of 600 mm or above. All geometric tolerances are ascertained using a two-dimensional slot gauge. This is a level plastic gauge with a defined slot. The glass-ceramic panel must fit easily in the gauge. We will be happy to provide you with a drawing of the slot gauge on request. 2.3 Shaped glass-ceramic panels Curved ROBAX® glass-ceramic panels are available in a number of different variants. 2.3.1 Curved Minimum bending radius R: 200 mm. Special sizes on request. All sizes are outer dimensions.
