Seeking help regarding centrifugal fans

Pressure-containing parts other than the fan housing, but including accessories, shall be tested hydrostatically using a liquid at a pressure of at least 11/2 times the maximum allowable working pressure, and in any case not less than a gauge pressure of 1.5 bar (20 psig). What does this sentence mean? (I understand the English meaning, so no translation is needed.) Is it necessary to apply hydraulic pressure to the fan housing? If not, why?

All pressure-bearing components (except the fan casing, including all accessories) should undergo a hydrostatic test, with the test pressure being at least 1.5 times the maximum allowable pressure, but not less than 1.5 bar gauge pressure. This is API673, right? It seems that the casing doesn’t require a hydrostatic test; I’ll do some research on it
It couldn’t be detected; I’m not quite sure. I’m sorry, I can’t just give you a casual answer.
I, who scored 60 on the English test, find it extremely stressful. But I also learn*learn*
Could you explain why?
The English technical documentation you provided means exactly this; if you’re not sure about the details, it’s fine to email the manufacturer and ask them to provide an explanation. Since I’m not exactly sure what kind of device it is, I can’t be certain; it’s just based on the information you’ve provided. If there are pictures, we can analyze them together
It’s just a sentence in API617; I don’t understand why such a requirement exists
Pressure vessel components other than the fan casing, including additives, shall be subjected to a hydrostatic test using a liquid at a pressure of at least 1.5 times the maximum allowable working pressure, but not less than 1.5 bar gauge pressure (20 psig).
