Straightness measurement

Instructions for measuring the straightness of steel.

Straightness measuring, test procedure

The deviation from straightness (arrow height) is measured with the bar resting on the horizontal surface. Arrow height is measured in the horizontal direction the length of the bar (L).

Straightness max 1,7 mm, q per meter. Which means a maximum of 5,1 mm on a steel with a length of 3000 mm.

q ≤ 0,17 % x L (see Ngure below).
