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 (except for related specification sheets), 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 Specification sheets. The individual item requirements shall be as specified herein and in accordance with
the applicable specification sheet. In the event of any conflict between the requirements of this specification and the
specification sheet, the latter shall govern.
3.2 First article. When specified (see 6.2), a sample shall be subjected to first article inspection in accordance
with 4.2.
3.3 Materials. Materials shall be as specified (see 3.1). Sufficient material identifications and controls shall be
exercised by the contractor to assure that the final product conforms to this specification.
3.3.1 Material control. Chemical analysis and physical properties of material per heat from the mill shall be
traceable from the bar stock to the final product. Material identity shall be maintained throughout the manufacturing
process. When specified (see 6.2), material control objective quality evidence shall be prepared.
3.3.2 Hull insert plugs, connector bodies, nuts, and washers. Unless otherwise specified (see 3.1), hull insert
plugs, connector bodies, nuts, and washers shall be manufactured from mill annealed Ni-Cu-Al alloy in accordance
with QQ-N-286. The Ni-Cu-Al alloy shall be age hardened either before machining or after machining and welding
to obtain 130,000 pounds force per square inch (lbf/in2) minimum tensile strength, 85,000 lbf/in2 minimum yield
strength at 0.2 percent offset, and 20 percent minimum elongation.
3.3.2.1 Receptacle bodies. Unless otherwise specified (see 3.1), receptacle bodies shall be manufactured from
Ni-Cu alloy in accordance with Class A, Form 1, hot finished of QQ-N-281 with a minimum yield strength of
40,000 lbf/in2 at 0.2 percent offset, or Ni-Cu alloy in accordance with Class A, Form 1, cold drawn of QQ-N-281
with a minimum yield strength of 50,000 lbf/in2 at 0.2 percent offset. The chemical and physical analysis furnished
by the mill will satisfy certification requirements when supplemented by the required traceability markings
identifying the finished receptacle bodies to the bar stock on which the chemical and physical analysis was
conducted. When specified (see 6.2), material control objective quality evidence shall be prepared.
