TESTING PROTOCOL



We mainly did four planed tests and three ad hoc tests. Though they may have been quite crude they were functional.

Bonding of the decoration to the plastic. We took one of the lenses that had a decoration on it we thought was our best solution. I took a wooden tongue depressor and vigorously rubbed it across the full surface of a letter. I believe I rubbed it across the "A" and tried to hit as many edges as I could. At no time was there any hint of separation. Conclusion: I would like to run this test again using a different instrument and see just what I have to do to make it fail.

What we defined as a failure: The lens shows any signs of cracking or outright breaking.



Drop test: Just like it sounds, we took the lens and dropped it three times each on all six sides of the lens from three and six feet. We used a step ladder and attached a tape measure to it so we could accurately repeat the test. With each drop, we recorded any damage save for scratches and rash marks from hitting the cement floor. Conclusion: After dropping the SAME lens 32 times we finally had a failure.




Controlled impact test: New lens. Projectiles dropped through tube to aim at target. From 4 and six feet we drop three weights: .25, .35 and .5. The impact surface area was estimated to be somewhat equal.
Conclusion: All the drops produced no failure save for abrasions
comments: I would like to to have continued with more and more weight until failure but this did not seem practical in a real life situation


Tumble test: from three and six feet. Take a lens and randomly spin it so it can land on any surface or edge. Do this three times from three feet and six feet.
Results: The lens did not break.
Conclusion: Lens easy absorbed all impact forces

AD HOC TESTS:

AD HOC test 1: Angry spouse test: Throw the lens across the shop on the cement floor: I tossed the lens estimated 10 feet.

Results: I did not see any damage that probably wasn't there before.
Conclusion: tossing the lens this distance did no damage. Spouse could throw lens in anger and it would probably not break.
Comments: I do not have an angry spouse therefore I could not conclude how far and hard the lenses could have been thrown. I would assume at some point they would reach terminal velocity.

AD HOC test 2: Bash test: Take a typical hammer and break the lens

Results: I hit the lens in various places where there I believed would be extra stress and save for abrasion scratches from the hammer and the expected damage to the decoration, there was no damage
Conclusion: You can smack your lenses with a typical household hammer and they won't break.
Comments: I was very confident in the toughness of the lens as I am not wearing safety glasses. If you do choose to smack your own lenses, there may leave behind abrasions from the hammer. Keep in mind, I sell my lenses in pairs.


AD HOC test 3: Arbor press: Break a lens using an arbor press the arbor press has a contact area of 1.25^2 =1.5625 sq inches

We started by placing a scale under the lens and and applied pressure. The scale maxed out at 50 pounds with no difficulty. We next removed the scale and continued to apply additional pressure.
Results: The pressing of the arbor caused the sides to splay out but never failed.
Conclusion: The lens is one tough lens and you will probably see other damages to other parts of the car before you see damage to the lens

Actually, I think these tests far exceed what a stock lens could take, so congratulations on these results for sure! How long until a finalized product will be available? Curious minds want to know......

I knew your grandma and you are right! She could sink a railroad spike in three swings! She was a husky woman and a good kisser too!

We still have a little ways to go. I have to approve T2s before we can go on to our next step. We have got the decoration finally settled in and currently they are setting up shop. They have to shoot them and palletize them. We will probably fly the pre order quantity to The States first so we can get these decorated and on their way. I have been telling people late fall but man, I gotta tell ya, that is just a guess. But lets have a reality check here. We all know something of this size can get snagged. .......George and The Team have been greasing the wheels. The best I can do is tell you all to keep an eye on the thread and either .......George or I will post progress reports as we can.
