Tolerance

(a) Width: Mill-Run: ± 1/8”
Square-Cut: ± 1/16”

(b) Length: variation is listed in the following table.

Length Mill-Run Square-Cut
0″ to  48″ 0″ to +3/4″ -1/16″ to +1/8″
48″ to 96″ 0″ to  +1 1/2″ -1/8″ to +1/4″
> 96″ 0″ to (1 1/2″ + 1/4″ x N*) ± 1/4″

 

(c) Thickness: ± 5%

(d) Unit Weight: ± 5%

(e) Surface Treatment (ASTM D2578): > 46 dyne/cm (2 to 8 mm in thickness)
> 42 dyne/cm (10 mm in thickness)

(f) Square Tolerance is the difference of the two diagonals of the sheet.

 

Length Mill-Run Square-Cut
