2.4 Order of precedence. Unless otherwise noted herein or in the contract, in the event of a conflict
between the text of this document and the references cited herein, the text of this document takes
precedence. Nothing in this document, however, supersedes applicable laws and regulations unless a
specific exemption has been obtained.
3. REQUIREMENTS
3.1 First article. When specified in the contract or purchase order (see 6.2), first article testing shall
be required and all test samples required by this specification shall be made available to the
contracting officer or his authorized representative for approval in accordance with 4.3. First article
testing shall be completed before production material is submitted for acceptance testing. The
approval of the first article samples authorizes commencement of production but does not relieve
the supplier of the responsibility to comply with all the applicable provisions of this specification.
The first article samples and acceptance test plates shall be manufactured by the process proposed
for use on production items.
3.2 Chemical composition. The chemical composition of the plates shall be within the limits shown
in Table I. The limits specified in Table I were taken from Teal Sheets from the Aluminum
Association dated 2009-03-01 registered composition limits for Aluminum Alloys. A certification
of conformance of the chemical composition of the alloy shall be furnished with the ballistic test
plates.
3.3 Mechanical properties. Unless otherwise specified in the contract or order (see 6.2), the
mechanical properties of the test specimen taken in the longitudinal transverse (LT) direction shall
meet the minimum mechanical properties listed in Table II. If mechanical property requirements
differ from those contained in Table II, or if any other properties are required, the ballistic
requirements shall be negotiated between the procuring activity and the supplier.
