Teak doors

Here is an example of shop testing. No research lab necessary. The video shows a door being tested in the shop for stiffness. Interesting that the weak point of the door is right in the middle where the two panels meet. The objective of this test was to see if the doors were strong enough to hold back water, lots of water, 254 cubic feet of the salty stuff.
This was required by Transport Canada as the doors that were just for privacy now need for stability and safety.
We had no interest in tearing out the Teak doors and replacing them with steel doors, so we had to come up with something acceptable. First we tested the doors, then we split the door in half and epoxied Maranti plywood in between. The customer was very happy to have the original doors while Transport Canada was able to certified them. How great was that!
