Question

The standing pressure test for positive pressure medical gas piping shall be conducted with the source valve closed and the vacuum system subjected to which test time and pressure?

A) 8 hours at 150 psi.
B) 8 hours at 20% above operating pressure.
C) 24 hours at 150 psi.
D) 24 hours at 20% above normal operating pressure.

Answer 1

The correct test for positive pressure medical gas piping is D) 24 hours at 20% above normal operating pressure, ensuring the system's integrity and safety.

Step-by-step explanation:

The standing pressure test for positive pressure medical gas piping requires a specific period and pressure to ensure the system's integrity. According to typical standards, this test often requires maintaining a certain pressure level over an extended period to verify that the system does not have any leaks.

In this case, the correct answer to the question about the vacuum system subjected to the standing pressure test is D) 24 hours at 20% above normal operating pressure. This requirement is designed to simulate conditions that are more extreme than the system's regular usage to guarantee that the system will function safely under normal conditions. This is crucial for medical gas systems where reliability and safety are of utmost importance.
