Straightness: 
IntePro may
slightly curve in along flute direction. The straightness is
related to the ratio of length and width of IntePro board. The
more slender the board is, the more obvious the curve is. The
straightness can be obtained from measuring the maximum gap
between a straight edge and an IntePro board when the two
corners of IntePro board touch the straight edge. The tolerance
of straightness of millrun IntePro is listed in the following
two tables.

(h) 
Warp is the height of the “hump” when an IntePro board is
laid on a flat surface. The warp tolerance can be found out from
the following table.
