3.2.7 Dimensions and tolerances.
3.2.7.1 Dimensions. Plates shall comply with the dimensions specified in the applicable
drawings or in the contract or order (see 6.2).
3.2.7.2 Thickness. The thickness tolerance of each plate, after final treatment, shall be in
accordance with table III for the thickness specified.
3.2.7.3 Flatness. Unless otherwise specified in the contract or order, the flatness tolerance
of each plate shall be within the requirements specified in table IV. Tighter tolerance
requirements shall be specified in the contract or order and shall be as agreed upon between
the contractor and the procuring activity.
3.2.7.4 Waviness. Unless otherwise specified in the contract or order, the waviness
tolerance of each plate shall be within the requirements of table V.
3.2.8 Identification marking. Identification marking shall be legibly painted and records
shall be such as to ensure positive identification of all plates, including test samples and
specimens, with the lot and corresponding heat from which they were produced. Marking

symbols shall be furnished to the inspector prior to submittal for inspection. First article
and acceptance ballistic test plates shall also be marked with the manufacturer's name or
trademark, the number of this specification, and the ordered plate thickness in inches. First
article plates shall be marked "PRE," acceptance plates "ACC," and retest plates shall be
marked "Rl" and "R2." If a second set of retest plates are submitted they shall be marked
"RR1" and "RR2." The primary plate rolling direction shall be identified.
3.2.9 Workmanship.
3.2.9.1 Surface condition. The top and bottom surface of each plate shall be free from the
following surface defects: slivers, laps, checks, seams, blisters, snakes, cold shuts, cracks,
burning, mechanical seams, mechanical gouges and laminations (see 6.10). The surface of
each plate shall be such that mill scale or oxidation product shall not interfere with
determination of acceptability. Imperfections listed above, which are of such a nature as to
affect the fabrication of the materials, shall be rejected.
