MIL-DTL-46177C(MR)
4.6.4 Ballistic tests. Ballistic testing of the plate shall be conducted at a
Government test facility specified in the contract or order (see 6.2). Testing
shall be conducted in accordance with the requirements of the appendix to this
specification.
4.6.5 Reduced testing. At the discretion of the procuring activity, the amount
of testing may be reduced provided the results on consecutive lots indicate that
a satisfactory uniform product meeting the testing requirements is being produced
(see 6.2). Reduced testing shall be in accordance with a system previously
approved or established by the procuring activity involved.
4.6.6
Rejection and retest.
4.6.6.1 Rejection. Unless otherwise specified in the contract or order (see 6.2),
failure of the first article samples to meet the requirements of this specification
shall be cause for rejection of the process, and failure of the acceptance samples
to meet the requirements of this specification shall be cause for rejection of the
lot (see 4.6.6.2).
4.6.6.2 Retest. Unless a specific retest procedure is specified in the contract
or order (see 6.2), two retest samples shall be submitted for each failed sample.
Failure of either of the retest samples (plates) shall be cause for rejection of
the material. First article retests shall not be permitted until the supplier
has made the necessary corrections in the processing of the material to the
satisfaction of the procuring activity.
4.6.7 Bend test. The bend test shall be conducted in accordance with ASTM E290
using method Arrangement C.
4.6.8 Hardness traverse test. Prior to production to assure compliance to
paragraph 3.2.11.2, the size of the heat affected zone for thermally cut edges
shall be determined by taking Rockwell C hardness tests at 1/16 inch increments
from the edge. Surface scale and decarburization shall be removed from the test
surface. The distance at which there is no change in surface hardness shall be
considered the depth of the heat affected zone. The contractor shall document
the test results for each thickness and thermal cutting method used in
production. The contractor is also responsible for documenting all heat input
controls to assure the cutting process is under control. Re-verification of heat
affected zone size for subsequent production lots is not required provided there
is no change in the cutting method or heat input from that previously tested.
The records shall be available for review by the cognizant government
representative.
5.
PACKAGING
5.1 Packaging. For acquisition purposes, the packaging requirements shall be as
specified in the contract or order (see 6.2). When actual packaging of materiel
is to be performed by DoD personnel, these personnel need to contact the
responsible packaging activity to ascertain requisite packaging requirements.
Packaging requirements are maintained by the Inventory Control Point's packaging
activity within the Military Department or Defense Agency, or within the Military
Department's System Command. Packaging data retrieval is available from the
managing Military Department's or Defense Agency's automated packaging files,
CD-ROM products, or by contacting the responsible packaging activity.
