What is the maximum increment and maximum pressure used when testing gas gauges?

• A. 1/2 Pound Increments Up To 5 Psi
• B. 1/4 Pound Increments Up To 2 Psi
• C. 1 Pound Increments Up To 10 Psi
• D. 3/4 Pound Increments Up To 8 Psi

Answer: (A)

When testing gas piping for leaks, you want to apply pressure in small, controlled steps and keep the test pressure within a safe limit. The standard approach is to increase pressure in increments of 0.5 psi and not exceed a test pressure of 5 psi. This combination lets you detect even small leaks without overloading the system or stressing components like regulators, meters, and joints. If a leak is present, pressure will drop or bubbles will appear during the test; if not, the system passes the test after the specified hold time. The other options use larger steps or a higher maximum pressure that don’t align with common testing practices, which could miss leaks or risk damage to equipment.
