This specification covers the materials, dimensional tolerances, constructions, and mechanical properties for standard metallic implantable strands and cables. Materials shall be manufactured using equivalent size wires in the cold-worked and stress-relieved or annealed condition. Standard strand constructions shall be 1×3, 1×7, and 1×19 strand. Cabling constructions shall be 7×7 and 7×19 cable. Mechanical requirements include ultimate tensile strength and minimum breaking force. Strand or cable shall have no welds or splices, free of imperfections, and shall conform to dimensions, surface finish, and tolerances indicated in this specification.

1.1 This specification covers the materials, dimensional tolerances, constructions, and mechanical properties for standard metallic implantable strands and cables.

1.2 This specification is intended to assist in the development of specific strand and cable specifications. It is particularly appropriate for high load bearing applications. It is not intended however, to address all of the possible variations in construction, material, or properties.

1.3 The values stated in SI units are to be regarded as standard. The inch-pound equivalents may be approximate.
