Note 1: Plates over 32 mm in thickness may be supplied with either as rolled or gas-cut edges. In case of Bhilai plates, above 40 mm thick plates shall be supplied with flame cut edges.The tolerances on width in such cases shall be subject to arrangement between the purchaser and the supplier.
Note 2
: In case plates below 32 mm in thickness are supplied in as- rolled condition the tolerances shall be mutually agreed to between the purchaser and the supplier.

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

(c) One in the middle of the length.

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.
