(1) Ellipsoidal Head #1 limits the UG-99(b) stress ratio.

(2) The zero degree angular position is assumed to be up, and the test liquidheight is assumed to the top-most flange.

The field test condition has not been investigated.

The test temperature of 21.11 °C is warmer than the minimum recommended temperature of -12 °C so the brittlefracture provision of UG-99(h) has been met.
