NOTE: Tolerance includes allowance for convexity and concavity. For rectangular sections, the tolerance calculated for the larger flat dimension shall also apply to the smaller flat dimension. This tolerance shall be increased by 50% when applied to the smaller dimension for rectangular sections whose ratio of cross-sectional dimensions is between 1.5 and 3, and by 100% when this ratio exceeds 3.
