WebWhat is Flatness Tolerance in GD&T? Flatness in gd&t is a type of foam control GD&T tolerance. It controls the variations in a flat surface, regardless of any datum feature. In this way, it ensures the controlled surface is flat enough to perform the required function. The flatness tolerance value is always less than the dimensional tolerance ... WebFlatness and edge waviness tolerances. In contrast to the standards replaced, BS EN 10259 introduces tolerances for flatness of sheet, plate and cut lengths, with both a ‘normal’ and ‘special’ range. There is a larger tolerance range above 3000mm lengths. This greater tolerance also applies to strip, for which there is also a limitation ...
