 Sitting in the tube, they should last for 1000's of
years. Moisture is about the only problem. Keep them
in a zip-loc with a packet a silca-gel and they will
out live you and your grandchildren's grandchildren.
Any temperature that a human can live in will have
virtually no effect on them.

 If these are NOS and not test pulls, they should all be
functional. No need to test them unless you just feel
the urge.
