    Jul 15, 2012 · But the question asked above is , "How to check flatness and waviness in ASTM A6?" I think that is a fair question since ASTM A6 does not give a method how to inspect flatness of plate, it only states that plates must be in a horizontal position on a flat surface when flatness is measured.

    The variation in straightness of members is measured in the same manner as the ASTM A6 mill tolerances. Again, there are two categories—members without specified camber (straight) and members with specified camber. Straight members not intended to be used as compression members have no tolerance requirements beyond ASTM A6.

    Flatness Control Perfect flatness is when all points of a surface lie in the same plane. Flatness is a form control. The flatness control (c) defines how much a surface on a real part may vary from the ideal flat plane. Tolerance Zone The flatness tolerance zone is the volume between two parallel planes.
