Maybe a company brings several plates of different design with various modifications and tests which are best for passing NIJ tests and that model is certified.

I have been sent a description of the protocol for the certified lab test for NIJ certification. It is:


"Twenty (20) plates plates are submitted to NIJ
Out of that- 10 are picked for testing
Out of that- 3 are randomly picked for shooting
Heated Clay is pulled out and put into the 5/12 inch deep box. A steel ball is dropped from a 'given' distance and the divot is measured 2 times. This is to verify the clay is not to cold or stiff....the temp stored is just as the human body for back face deformation.

Next is a : 6 shot test - the first 2 shots target top left then bottom right of plate for shot 1 and 2. The plate is then pulled and measured for back face deformation.
The plate is put back on the heated clay to shoot the other 4 shots. Those 4 shots just can not penetrate.

Three of remaining plates are then time tested and are put through an accelerated weathering equivalent of 5 years. This includes a soaking in water for a for days then exposed high a high heat protocol.

Once the 'weathering' is completed, that plate is then shot.

This entire process, IF FAST TRACKED will take 2-3 weeks. THIS IS JUST THE TESTING.

Then the results are submitted to NIJ. This process takes 1 to 3 months...for the rubber stamp."

Now that I see this, this makes more sense and does 'ring a bell'
