4.6.2 For conformance inspection.
4.6.2.1 For chemical analysis. A sample sufficient to perform the analysis required to
determine compliance with 3.2 shall be selected from each lot.
4.6.2.2 For mechanical properties (See 3.3).
4.6.2.2.1 Number of samples. Two random samples shall be taken from each lot. If a lot
consists of only one plate, only one sample shall be selected. At least one tension test
specimen shall be made from each sample.

Ballistic acceptance requirements have not yet been determined.
4.6.2.2.2 Types of test specimens. Tension test specimens shall conform to the largest
obtainable round cross-section specimen shown in ASTM E8.
4.6.2.2.3 Location of test specimens. Transverse test specimens shall be taken from the plate
perpendicular to the primary rolling direction with the central longitudinal axis midway
between the top and bottom surfaces of the plate. Longitudinal specimens shall be prepared in
such a manner that the longitudinal axis of the specimen is parallel to the principal rolling
direction of the sample with the central longitudinal axis midway between the top and bottom
surfaces of the plate.
4.6.2.3 For ballistic testing. According to the thickness of the plate represented (ordered plate
thickness) one plate, 12 inch by 12 inch for thicknesses less than 0.615 inch or 18 inch by 12
inch for thicknesses 0.615 inch to 3.249 inch or 24 inch by 12 inch for thicknesses 3.250 inch
and greater shall be selected from every lot of material of the same thickness. In the event of
reduced testing (see 4.8.4), multiple lots represented by a single acceptance ballistic test shall
have been manufactured using the same heat treatment and other processing within standard
mill parameters of a fixed process.
4.7 Examination.
4.7.1 Visual. Each piece in each lot shall be visually examined for compliance with the
requirements for workmanship (see 3.9) and marking for identification (see 3.6).
