I need help: is it necessary to apply water pressure after the superheater of a waste heat boiler has been installed? If necessary, should it be installed separately or together with the boiler?

After the waste heat boiler in our project was installed, I noticed that the superheater section (including the second-stage superheater and the desuperheater) was not included in the overall hydrostatic test. Is this correct? Is it in compliance with the standards?
Performed together with the boiler hydrotest.
It can be pressurized together with the drum of the waste heat boiler; here we always pressurize everything at the same time, and during pressurization the safety valves and manual valves in various locations are closed
Fight together; why fight separately? Of course, pressures that are different need to be separated. For a system, it still needs to be fought together
The superheater is a pressure-bearing component and must be pressurized
