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 4.3.
3.3 Materials. Materials shall be as identified herein. However, when a definite material is not specified,
a material shall be used which will enable the connectors to meet all requirements of this specification.
Acceptance or approval of any constituent material shall not be construed as a guarantee for acceptance
of the finished product.
3.3.1 Interface materials, platings and processes. Interface materials, platings, and processes have
been established to provide assurances that connectors manufactured to this specification will properly
interface to similar industry standard or government specified connector systems without problems of
electrochemical incompatibility or excessive interface surface wear. The manufacturers of connectors
supplied to this specification may be allowed to use alternate recognized industry standard materials,
platings, and processes from those identified in 3.3. Alternate materials, platings and processes used
must be coordinated with the qualifying activity as part of the qualification process. Use of alternates to
those referenced guidance items by the supplier must not result in inferior short or long term performance
or reliability of supplied connectors as compared with connectors manufactured using the referenced
materials, platings, or processes. Short or long term failures or reliability problems due to use of these
alternates shall be the responsibility of the supplier.
3.3.2 Recycled, recovered, or environmentally preferable materials. Recycled, recovered or
environmentally preferable materials should be used to the maximum extent possible provided that the
material meets or exceeds the operational and maintenance requirements, and promotes economically
advantageous life cycle costs.
3.3.3. Metals and finishes. All exposed metal parts, other than electrical contacts, may be aluminum,
aluminum alloy, brass, steel or corrosion resistant steel. All exposed metal parts, other than electrical
contacts, shall be cadmium plated in accordance with SAE-AMS-QQ-P-416, type II, class 3, except that
preliminary plating of other metal will be permissible. The resultant finish shall be electrically conductive.
