I wonder if "damp" modes of decay could still damage them though, which isn't captured in this style of testing. Like some wet chemical or biological process.

Mechanical decay would also damage them. I think it’s assumed that the media will be stored in a place protected from humidity, chemicals and hammers.

		Yes I suppose a strong casing can protect against all that, but not against temperature so that's the one thing they still need to test for.
