Well, it depends. I am familiar with the two tables you reference from
454, however, that deals with the basic plastic materials, which are
predominantly non-nutrient. Where you get into the issues are the
additives that you add to these, which might be nutrient. I agree that it
is not a cut and dried thing, but those requirements have been in there
for a LONG time and are rooted in the 60s. I really don't think they are
applicable anymore, considering modern materials of construction.

RE: [TN] fungus question
Don't think you can generalize fungus compatibility that way. If you look
at MIL-HDBK-454, section 4, you'll see about a 60-40 split amongst the
plastics listed as to whether they're fungus inert or potentially fungus
nutrient.

Good morning all,
Do any of you know whether electronic components are still tested for
fungus resistance? Since most components are molded plastic made from
synthetic or petroleum-based materials, and therefore non-nutrient, I
suspect that this kind of testing is no longer done, unless required to by
a customer.
Thanks.
