Flatcat. . . hope you don't mind if I respond to your question.

I've got first hand experience in a certified testing lab for aircraft materials, though none of my testing was done with NIJ specs.

If my memory serves me correctly after reviewing the NIJ testing protocols a couple of weeks ago, this statement may refer to one or two protocols.

In one of the tests, the vest/material is tested after they are 'conditioned'. In this test, the vest/material is tumbled under controlled conditions, temp, humidity, time, etc, in order to replicate use of the vest.

Additionally, all 'certified' material testing in general, whether it be Kryron, or a rubber like material, needs to be tested in a conditioned state. This means that the material that is to undergo testing needs to at a certain temperature and humidity ranges for a given time period, usually at least 24 hours, depending on the material/item.

Testing a material that is 100° will test differently than the same material at 50°
