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.
