3. REQUIREMENTS

3.1 Specification sheets. The individual item requirements shall be as specified herein and as specifed

in 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. Wires furnished under this specification shall be products that are authorized by the

qualifying activity for listing on the applicable qualified products list (QPL) before contract award (see 4.6

and 6.3).

3.3 Materials. The materials for the principal components of the wire shall be as specified herein.

Prior approval to use substitute material must be obtained from the qualifying activity. When a definite

material is not specified, a material shall be used that will enable the finished products 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. All materials used in the

manufacture of wires furnished hereunder shall be of such quality and form that the finished product

conforms to the requirements of this specification. All materials used shall conform to the requirements

specified herein.

3.3.1 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.

3.3.2 Conductor material. Strands used in the manufacture of conductors shall be annealed or soft

drawn copper wire from the best obtainable, commercially pure wire bars, and as specified in A-A-59551.
