(1) Cylinder #1 limits the UG-99(b) stress ratio.(2) The zero degree angular position is assumed to be up, andthe test liquid height is assumed to the top-most flange.

The field test condition has not been investigated.

The test temperature of 70 F is warmer than the minimum recommended temperature of 10 F so the brittle fractureprovision of UG-99(h) has been met.
