TABLE A1.14 Permissible Variations in Flatness for Annealed Plates
NOTE 1—Tolerances in this table apply to plates up to 15 ft (4572 mm) in length, or to any 15 ft (4572 mm) of longer plates.
NOTE 2—If the longer dimension is under 36 in. (914 mm), the tolerance is not greater than ⁄4 in. (6.35 mm).
NOTE 3—For plates with specified minimum yield strengths of 35 ksi (240 MPa) or more, and all steels of Specification A693, the permissible
variations are increased to 1 ⁄2 times the amounts shown below.

Camber is the deviation of a side edge from a straight line, and measurement is
taken by placing a 5-ft straightedge on the concave side and measuring the
greatest distance between the plate and the straightedge.
