When pressurizing a low-pressure appliance to search for leaks, what is the maximum pressure a technician may apply?
a.15 psig
b.10 psig
c.5 psig
d.20 psig
解析
A low-pressure appliance must never be pressurized above 10 psig. The shell is protected by a rupture disk that typically relieves at 15 psig, so staying under 10 psig keeps a safe margin below that disk. Higher pressures risk bursting the rupture disk and venting the charge.
