Which formula for the test pressure should be used during the horizontal hydrostatic testing of vertical containers?

Which formula should be used to determine the test pressure during the horizontal hydrostatic testing of vertical containers? 1. 1.25x design pressure x stress ratio + hydrostatic pressure of the liquid column; 2. 1.25x (design pressure + hydrostatic pressure of the liquid column) x stress ratio. Which one should be chosen?
The first one. The hydrostatic pressure of the liquid column was added only to verify the bottom head.
According to the first method: 1.25x design pressure x stress ratio + hydrostatic pressure of the liquid column

If the hydrostatic pressure of the liquid column is less than 5% of the design pressure, it can be ignored
Choose the first option; the calculation basis is the top pressure, and the Wild Boar Spirit pressure is added only for verifying the bottom head.
If the hydrostatic pressure of the liquid column is less than 5% of the design pressure, can both the pressure test pressure and the calculated pressure ignore the hydrostatic pressure of the liquid column?
