3. CERTIFICATION, TESTING & INSPECTION
Provide wire rope which is the standard product of a manufacturer regularly engaged in the manufacture of wire rope, and that essentially duplicate products having been in satisfactory used for at least 5 years.

3.1 Steel shall be milled within the borders of the United States of America, using only domestic construction materials in accordance with the Federal Acquisition Regulation (FAR), Subpart 25.6. Steel shall be certified for material composition and mill.

3.2 Wire rope shall be factory inspected to ensure that it is free from defects. Documentation showing all factory tests and inspections shall be supplied to the Government prior to shipment.

3.2.1 Pre-Stretching
Pre-stretch the wire rope. Test shall consist of three cycles at 40 percent of its nominal strength. Hold the 40 percent loads for 5 minutes with 5 percent loads for 5 minutes between cycles. A method of dynamic pre-stretching may be proposed.

3.2.2 Wire Strength and Ductility
Perform testing in accordance with Federal Specifications (FS), RR-W-410 to verify wire strength and ductility.

3.2.3 Weld Distribution
Wire joints in any strand must not be closer than 18 inches in any strand.

3.2.4 Strand Pitch Length
Not be less than 4-1/2 times the nominal rope diameter.

3.2.5 Core Strand Wires
The number of wires in the core strand must be equal to or greater than the number of wires in the other strands. Use the same material as the wires in the other strands, or use a material with a lower tensile strength.

3.2.6 Tension Testing
Submit rope tension test report to the government no later than 3 calendar days after test is complete.
