Out of square

The out-of-square tolerance must be according to what is indicated in table 11 of the ASTM A568 standard.Out of square is the greatest deviation of the end of the edge from a straight line at right angles to one side touching the corner. It is also obtained by measuring the difference of diagonals. The out of square is half of this difference:The maximum out of square should be 1/16” per 6 inches width, that means, 1/8” / feet of width.

Measurement method: Direct measurement with tape measure
