MIL-A-46100D (MR)
plate it represents and large enough to obtain at least four specimens from the sample in
accordance with 4.6.3. For ballistic acceptance testing. One plate, of each thickness to be supplied on the
contract, shall be randomly taken from each lot for ballistic testing. In the event that two
ordered thicknesses that are 0.010 inches or less apart, are to be made from the same lot,
then only one of the ordered thicknesses need be submitted for acceptance testing. The
other ordered thickness, however, shall be included on the applicable reporting form with
the words indicating that it is represented by the sample to be tested. However, if the two
ordered thicknesses are such that each thickness requires testing with a different type
projectile as shown in table VI, then each of the ordered thicknesses shall be ballistically
tested. Unless otherwise specified, the plates shall be 12 inches by 36 inches. Test
projectiles shall be as specified in table VI. Bend test samples. Unless otherwise specified (see 6.2), two samples shall be
randomly taken from each lot for these tests representing the entire lot of material;
however, when an entire heat represents only one lot the samples shall be taken from the
first and last usable portion of the heat. Testing shall be conducted in accordance with 4.6.4
and shall meet the requirements of 3.2.5. Thermally cut plates. For plates thermally cut after heat treatment, one sample plate
per thickness shall be sampled and tested for hardness at two (2) locations perpendicular to
the cut edge in accordance with Plates not meeting the minimum requirement of shall be rejected. In addition, the edges of the plates shall be examined
nondestructively for cracks after cutting. DELETED.
4.5 Examination.
4.5.1 Visual. All steel plate shall be subject to visual inspection for compliance with the
requirements for identification marking (see 3.2.8) and for workmanship (see 3.2.9).
4.5.2 Dimensional. All steel plate shall be subject to inspection for compliance with
dimensional and tolerance requirements (see 3.2.7).
4.5.3 Preparation for shipment. Examination shall be made to determine compliance with
the requirements for preparation for shipment (see section 5).
4.6 Tests.
4.6.1 Chemical analysis. Chemical analysis shall be conducted in accordance with the
applicable method specified in ASTM A751 (see 6.5). The analysis shall comply with the
declared composition established in accordance with the requirements of table I (see 3.2.1).
4.6.2 Hardness tests. Brinell hardness tests (HB) shall be conducted in accordance with
ASTM E10, using a 10 mm carbide ball and a 3000 kilogram load. Surface scale and
