MIL-A-12560H (MR)
w/INT. AMENDMENT 4
APPENDIX A
A.4.1.3 Rejection and retest of ballistic plates.
A.4.1.3.1 First article tests (rejection). Unless noted otherwise in the contract or order, failure of
any one or more of the three first article test plates to meet the minimum ballistic requirements as
specified in the appendix to the specification indicates failure of the products and process.
A.4.1.3.2 First article (retests). Resubmission of ballistic retest plates shall not be made until the
manufacturer has made the necessary corrections in the processing of the material to the
satisfaction of the procuring activity. Three retest plates shall be submitted for first article testing
and all three shall pass.
A.4.1.3.3 Acceptance tests (rejection). Unless otherwise noted in the contract or order, failure of
a test plate to meet the ballistic requirement indicates failure of the lot; however, the final
decision shall depend on the outcome of retests, if submitted.
A.4.1.3.4 Acceptance tests (retests). If a test plate representing a lot fails to meet the ballistic
requirement, the manufacturer has the following options: Immediately upon notification of the
failure:
(1) At manufacturer's expense submit two additional test plates from the same lot for
ballistic retest, or
(2) First re-heat treat (quenching and tempering) the lot and then submit a test plate from the
re-treated lot, or
(3) Scrap the lot and submit a plate representing a new lot for acceptance.
If the manufacturer chooses any one of these options and the ballistic retest plate (or plates) meet
the requirements then the lot represented is acceptable. If he chooses option (1) and one or both
the retest plates fail, the manufacturer shall re-heat treat the lot and submit a test plate from the
re-treated lot. If this plate fails the lot is rejected. If the manufacturer chooses option (3) and the
test plate fails, the manufacturer shall again resort to any one of the three options.
A.4.1.4 Disposition of ballistic test plates.
A.4.1.4.1 First article test plates. Upon request of the applicant within 15 days after ballistic
testing, first article plates shall be returned "as is" to the applicant, at the applicant's expense,
unless the plates were destroyed in testing.
A.4.1.4.2 Acceptance test plates. Acceptance test plates that comply with the requirements of this
specification are considered as part of the lot of steel they represent and ownership of them
passes to the Government with the acceptance of that lot. Acceptance test plates that fail to
comply with the requirements of this specification are considered as part of the lot they represent
and remain the property of the producer just as the rejectable lot does. The failed plates shall be
returned, upon request, as in A.4.1.4.1
