Lab Tested?

08/11/2016 9:39 PM

I have a fastener that needs to hold a ~40 pound load. shear/static/in motion.. whatever.

I know from testing at the workbench that it can withstand over 1000 pounds without failure.

Not that anyone has asked, but should they ask? I want to know the ins and outs of obtaining the title of "independently lab tested" for said fastener? Who would I go to? what might be required and why?

This is not a hypothetical question. I'm looking for any personal experience or knowledge before I decide the next step.

Search for "test labs" or "mechanical test labs".

I used these guys ⇓ for years, but there are local labs in Chicago if they are not.

Delsen Testing Laboratories, Inc. | LinkedIn

Be prepared to pay.

Why is this fastener so over-engineered?

You could try UL, but they would really cost. I would just find a local civil engineering lab that does load tests on highway materials, maybe, and see if they can certify results.

I am not sure what type of rivet you have. I recommend that you look at (Federal Shock Class) FSC 5320 - Rivets and find out what type of rivet and application you want to get qualified (Independently Lab Test Certification).

Then I would contact a local Testing Laboratory for tests and costs (depends on metal class Al 3000, 4000, 6000. etc.).

It might be helpful to check with Defense Supply St9ockton, Hill Air Force Base, etc. to get qualified for FSC 5320.

What quantity are you talking about? If you want to sell commercially, or to the Military, you are entering a competitive field.

Good Luck in the contest.
