Camber sheets up to 4.0 mm should not exceed 5 mm to 1 m in length, thickness exceeding 4,0 mm - 8 mm to 1 m in length.
Deflection for cold-rolled sheet or semi-solid state should not exceed 1 mm per 100 mm width and 20 mm for 1 m length of the sheet. The deflection of the sheets of soft state is not regulated.
