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 mill-run IntePro is listed in the following two tables. |
Length of IntePro is < 96”
