Piping must be tested to what pressure?

Piping must be tested to what pressure?

• A. 60 psi or 1.5x working pressure
• B. 100 psi
• C. 2x working pressure
• D. 30 psi

Answer: (A)

Pressure testing of piping is done to verify that the system does not leak and can withstand service pressures. The test is set to provide enough margin above normal operation while staying within what the piping and fittings can safely handle. The standard approach is to test at the greater of 60 psi or 1.5 times the working pressure. This means if the working pressure is low enough that 1.5x would be under 60 psi, you still use 60 psi to ensure a minimum test level. If the working pressure is higher, you test to 1.5x that value to ensure leaks will be detected and the system can tolerate pressure spikes. So the correct practice is to use whichever is higher: 60 psi or 1.5 times the working pressure. Fixed values like 100 psi or 30 psi, or testing at 2x working pressure, don’t align with this margin-based requirement.
