(1) PL stresses at nozzle openings have been estimated using the method described in Division2 Part 4.5.(2) 1.5*0.9*Sy used as the basis for the maximum local primary membrane stress at the nozzleintersection PL.(3) The zero degree angular position is assumed to be up, and the test liquid height is assumedto the top-most flange.

The field test condition has not been investigated.

The test temperature of 25 °C is warmer than the minimum recommended temperature of 6.9 °C so the brittlefracture provision of UG-99(h) has been met.
