Rolling and cutting tolerance for plates (as per IS 1852/85) with trimmed/
gas cut edges

Width
The tolerances on width of plate shall be as follows

Length mm	Width mm	Thickness mm	Tolerance on Width
Up to andincluding 8000	Up to andincluding 2000	Up to andincluding 20Over 20	+10mm+15 mm
Up to andincluding 8000	Over 2000	Up to andincluding 20Over 20	+0.5 % of width+20 mm
Over 8000	All widths	Up to andincluding 20Over 20	+ 0.2 % of length+ 0.3 % of length

Note 1 : Plates over 20 mm in thickness may be supplied with either as rolled or gas-cut edges.

Thickness
The tolerances on thickness shall be as follows:

Thickness	Tolerance in percentage of nominal Thickness
Less than 8 mm	+12.5, - 5.0
From 8 mm up to& including 12 mm	+7.5,- 5.0
Over 12mm	± 5.0

The thickness shall be measured at the following points

(a) One at each corner of the plate.

(b) One in the middle of the width, and

These measurements shall be 25 mm away from the edge and at points randomly chosen. The thickness measured at each of these points shall satisfy the tolerances specified above.

Length
The tolerances on length of plate produced in non- continuous mill shall be as follows :
