How are the hydrostatic test values determined in a boiler assembly plant?

According to the standards, for the drum in the component type, the water pressure is 1.25 times the normal value, with a holding time of 20 minutes; for other elements such as pipes, the pressure is 1.5 times the normal value, with a holding time measured in seconds or 5 minutes. So, how should the hydrostatic test values be determined for the assemblies of the upper and lower drum sections and the convection tubes (including the membrane wall)?
Refer to the tests on the compressed side, or consult the manufacturer for reference.
