Flatness is measured as the maximum deviation from a horizontal flat service. Tables show the permissible deviations from flat for plates up to 4 metre in length or for any 4 metre length of longer plates. For carbon steels with a carbon content higher than 0.33%, the values in Table are increased by 50%.
