Alternatives to Electrodeposited Cadmium for Corrosion Protection and Threaded Part Lubricity Applications (The Boeing Company, formerly BISDS)
Project Number: J-95-MF-006

Joint Test Protocol

The JTP contains the critical requirements and tests necessary to qualify potential alternatives to selected target HazMats and processes for a particular application. These tests were derived from engineering, performance, and operational impact (supportability) requirements defined by a consensus of government and industry participants. The JTP includes 17 common tests agreed upon by the joint group:

1. Appearance
2. Bent Cathode Thickness Uniformity
3. X-ray Fluorescence Alloy Composition Uniformity
4. Repairability
5. Unscribed Salt Spray (Fog) Corrosion Resistance
6. Scribed Salt Spray (Fog) Corrosion Resistance
7. Galvanic Corrosion Resistance
8. Fluid Corrosion Resistance Test
9. Bend Adhesion
10. Water Boil Adhesion
11. Wet Tape Paint Adhesion
12. Run-on and Breakaway Torque
13. Torque Tension
14. Sustained Tensile Load
15. Rotating Beam Fatigue
16. Temperature Limitations
17. Strippability of Coatings.

It also includes 3 program-specific, or "extended" tests identified by the Navy for at least one of its affected programs.

Extended (Program-Specific) Test Requirements:

1. Scribed SO2 Salt Spray Test
2. Scribed Carrier Exposure Corrosion Resistance
3. Extended Tension -Tension Fatigue Test.
