Does Ryton PPS meet the fungus resistance requirements of military specification (MIL-STD-45-4)?

Yes, two Ryton PPS products, R-4 and R-4 02XT have been evaluated by an independent laboratory (Truesdail Laboratories, Inc.) in accordance to MIL-STD-810D test method 508.3 and found not to allow fungus growth. The study was conducted over the prescribed twenty-eight days with the five fungi required by the test method. Observations were taken every seven days.

No fungus growth was observed on the Ryton PPS test specimens. More.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
