The published temperature range for the New (2014) Black AVT-PP-35 Tank is 35* F - 100* F (1.5*C - 37.5*C), and I believe (but don't quote me) that the tanks from previous years have the same or at least similar temperature range.
I can think of a handful of different ways that tanks could be exposed to conditions outside of that window, which makes me wonder if environmental conditions play some role in the tank ruptures...

1310s tank would have definitely seen temperatures (at least briefly) outside of that range, if only when transiting between their school and haul vehicle, and then into the venue. If the haul vehicle sat outside not running anywhere for a while, the tank could have conceivably seen temps in the neighborhood of -20C.

Well, its a failure, but at least its not a catastrophic failure of the part, resulting in explosive decompression and flying shrapnel.
