Oddy tests

The general consensus in the field of conservation seems to be that
the Oddy reactivity test is the grand-daddy or the mother of
(depending on which gender spin you prefer on your cliches) all
low-tech material testing.Okay, let's make it gender-neutral, and
call it the benchmark. If a material passes the Oddy, it is
considered "safe" for use in a museum exhibition or storage
environment.

Has anyone had any experience with materials passing the Oddy test
that have, upon subsequent use in the museum environment, proved not
to be nonreactive?   In other words, is there any evidence of the
Oddy test producing false negative results?
