Temperatures that may occur under extreme conditions but are very unlikely in use nor in shipping nor in a home environment. But there is a cumulative temperature time exposure under stress (the tensioning) that can cause stretching and loosening. Old TIII panels are usually resonating at low 30s hz, while they are tuned at the factory to something like 44hz. Granted that those are now 40 years old, but they do most of the change in the first couple of decades.
However, some have tried to retighten loose mylar with a hair drier the way you do with an Acoustat. ESL panel.
