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 Qualification. The connectors, adapters, protective covers, and stowage receptacles furnished
under this specification shall be products that are authorized by the qualifying activity for listing on the
applicable qualified product list before contract award (see 6.4).
3.2.1 Quality.
3.2.1.1 Statistical process control (SPC). The contractor shall implement and use SPC techniques in
the manufacturing process for parts covered by this specification. The SPC program shall be developed
and maintained in accordance with EIA-557. The SPC program shall be documented and maintained as
part of the overall reliability assurance program as specified in MIL-STD-790.
3.3 Materials. The materials shall be as specified herein. However, when a definite material is not
specified, a material shall be used which will enable the connectors and accessories to meet the
performance requirements of this specification. Acceptance or approval of any constituent material shall
not be construed as a guaranty of the acceptance of the finished product.
3.3.1 Nonmagnetic materials. All component parts shall be made from materials which are classed
as nonmagnetic (see 3.5).
3.3.2 Dissimilar metals and compatible couples. When dissimilar metals are used in intimate
contact with each other, protection against galvanic corrosion shall be provided. The use of dissimilar
metals in contact, which tend toward active galvanic corrosion (particularly brass, copper, or steel used in
contact with aluminum or aluminum alloy) is not acceptable. However, metal plating of dissimilar base
metals to provide similar or suitable abutting surfaces is permitted. The use of dissimilar metals
separated by a suitable insulating material is also permitted. Dissimilar metals and compatible couples
are defined in MIL-STD-889.
3.3.3 Shells and associated hardware. Shells, covers, coupling rings, stowage receptacles, and
cable sealing adapters shall be fabricated from high grade aluminum alloys.
3.3.4 Insert materials.
3.3.4.1 Resilient insert materials (classes C, J, and R). Resilient inserts shall be molded of a suitable
dielectric material and shall conform to ASTM D2000. The durometer hardness number shall be from 70
to 90.
3.3.4.2 Plastic insert materials (class L). Plastic inserts shall be fabricated from a plastic dielectric
and shall be capable of meeting the performance requirements of the class L connectors.
