This is from memory from a few years ago, and so may be wrong.
The fuel system I worked on was tested +/-60 Centrigrade. This applied to all components, those in the tank and those in the hull. Every unit shipped was tested, not just one test on the type. I think that testing was also done at 40,000 feet and ground level.
Can't remember the vibration testing, (possibly +/-8g) although I am sure this was performed on one unit that was then scrapped, and not on each shipped unit.
EMC susceptibility was also performed on one unit that was then scrapped.
These conditions would have been in the spec from Boeing/Airbus.
Hope this helps.
