Measures maximum deviation from a straight line along the longitudinal edge.

Measurement rule: For cut-edge or trimmed plates, thickness is measured at any point from the side edge. For mill-edge (untrimmed) plates, the measurement must be taken at least 25 mm from the edge. Tolerances for Width and Length

This means the deviation from a perfectly flat surface must be 8mm or less for the product to comply with JIS G 3193.
