Paulus Douglus,

I  see it in two ways.  Generally spoken, you are right. Not many fun guys 
become fungus today. However, another aspect is  this one: equipments are 
exposed to all sorts of environments, especially MILs, and all that spoky 
stuff that covers the electronic components can be broken down into all kind 
of unhealthy compounds, which can attack the 'plastics'.  So, the basic 
meaning with the tests is probably to see that the component in itself does 
not generate fungus, but there should be a second aspect, which points at 
what I said above.  Then comes the question: what do we mean with fungus. 
If we can harvest golden sepps for the evening meal, there is no doubt, but 
what about countless and nameless micro things. I have myself seen both 
metals and plastics covered by thin veils, which revealed millions of 
spectacular micro sized things that we could not name.  Looked like mycellum 
or mykorrhiza. That the 'things' were micron sized does not necessarily mean 
that they are harmless.

When I inspect units from different parts of the world, I can meet spiders, 
geckos, strange beatles and also strange coverings, sorts of. We don't do 
fungus testing, noone will pay for it, think that's the situation for the 
majority.

Why do you ask?  Maybe because of  a fan guy?

Inge
