2.3 Order of precedence. In the event of a conflict between the text of this document and the references cited herein (except for
related associated specifications or 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.
3.1.1 Reference critical interface materials, plating, and processes. The identified reference critical interface materials, plating,
and processes have been established to provide assurances that sockets manufactured to this specification will properly interface to
similar industry standards or government specified component interconnection systems without problems of electrochemical
contamination of critical electrical or mechanical interfaces or generation of incompatible mechanical interface surface wear products.
The manufacturers of sockets supplied to this specification are allowed to use alternate recognized industry standards for materials,
plating, and processes from those identified in 3.3 of this specification. Alternate materials, plating, 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 sockets as compared with sockets
manufactured using the referenced materials, plating, or processes. Short or long term failures or reliability problems due to use of
these alternates shall be the responsibility of the supplier.
3.2 Quality.
3.2.1 Qualification. Sockets furnished under this specification shall be products that are authorized by the qualifying activity for
listing on the applicable qualified products list before contract award (see 4.5 and 6.4).
3.3 Materials. Example reference materials are identified herein. However, when an example reference material is not identified,
a material shall be used which will enable the sockets and accessories to meet the performance requirements of this specification.
Acceptance or approval of a constituent material shall not be construed as a guaranty of acceptance of the finished product.
3.3.1 Recycled, recovered, or environmentally preferable material. Recycled, recovered, or environmentally preferable material
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.
3.3.2 Electrical contact gold guidelines. Electrical contact gold plating shall be in accordance with ASTM B488, type 2, code
C,.000030 (0.00076 mm) inch minimum thickness on the contact mating surface. Silver shall not be used as an underplate.
3.3.3 Socket (including termination). See figure 2.
3.3.3.1 Spring contact. The spring contact portion of the socket shall be beryllium copper in accordance ASTM B139, ASTM
B194, ASTM B196, copper-tin-nickel spinodial alloy C72900 in accordance with ASTM B740.
