Four months after we began testing, Durkee Testing Lab contacted us with the final result of the Tabor Abrasion tests.  We had reached failure at 56,200 cycles and never exceeded 1.29 mg per 1000 cycles.
Impact Resistance:

The most prevalent cause of failure to anodize is impact to an area.  The area around the impact micro-cracks and deleterious chemicals or the environment begins a galvanic or corrosion effect to the area.  Durkee Testing Lab performed impact tests on a TriPlex hard anodized panel utilizing a parabolic tip.  They began at 40 PSI (pounds per square inch) and increased by 10 PSI with each impact.  They achieved material failure at 140 PSI.  However the TriPlex anodize although torn apart, did not fracture at the point of impact or show signs of micro=cracking at the edges of the tear.
Boric Acid Testing:

Lights Camera Action, LLC needed an anodize that was resistant to a 5% to 7% boric acid solution for a period of five to fifteen years.  This solution is what surrounds the nuclear core, so failure of the anodize is not an option.  Taking five TriPlex hard anodize panels, Durkee Testing Lab documenting the pre-weight, and subsequently all five panels were submerged into 6% boric acid.

One panel was removed and neutralized each week until the final panel was fulled on the fifth week.   Durkee Testing Lab calculated the loss on each panel.   The results were better than expected.  Instead of five to fifteen years, Lights Camera Action, LLC's patented LED light could remain in the boric acid solution for 50 to 60 years without failure.
Corrosion Resistance:

Process: Corrosion resistance.  Sealed anodic coatings shall protect the substrate metal when subjected to the corrosion resistance test specified in 4.5.3.  Test specimens shall then be visually examined and shall show no more than a total of 15 isolated spots or pits, none larger than .031 inch in diameter, in a total of 15 square inches of test area grouped from five or more test pieces: no more than 5 isolated spots or pits, none larger than .031 inch in diameter, in a total of 30 square inches from one or more test pieces.  Areas within .062 inch from identification markings, edges and electrode contact marks remaining after processing shall be excluded.

The TriPlex panels were subjected to a salt spray test.  Durkee Testing Labs provided the testing services on a 6061-T6 panel.  At the end of 2904 hours (121 days) the group decided to call an end to the testing.  The TriPlex panels still showed no pits or evidence of any potential failure.

Abrasion Resistance

4.5.5 Abrasion resistance.  Test specimens, prepared in accordance with, shall be tested in accordance with Method 6192 of FED-STD-141 using CS-17 wheels with 1000gram load.  Wheels shall revolve on the anodic coating at a speed of 70 revolutions per minute (RPM) for 10,000 cycles.  Test specimens shall be weighed to the nearest milligram before (W1) and after (W1) abrading.  Weight loss obtained by subtracting the final weight from the initial weight, (N1-W2), shall be used to determine compliance with the requirements of (Nominal thickness of coating shall be .002 (2mils) +/- 20% for coating up to .002 (2 mils)).

After 10,000 cycles the initial panel was returned to us.  The only noticeable change was a polished ring where the abrasion wheels had tried to abrade the surface.  There was no visual or tactile change in the surface.  Durkee Testing Lab stated that nothing was happening except they were polishing the surface of our panel and we were wearing out their abrasion wheels.
