What is the minimum pressure test that should be conducted regardless of the design pressure?

The minimum pressure test that should be conducted, regardless of the design pressure, is 3 psig. This standard ensures that all systems are tested to a level that can reliably verify the integrity and safety of the propane gas system. Conducting a pressure test at this level helps identify any potential leaks in the system, ensuring that connections, valves, and components are all functioning properly under typical operational conditions.

Testing at 3 psig provides a sufficient margin above typical atmospheric pressure to detect vulnerabilities. It is a common industry practice to implement this baseline pressure during initial installations or any maintenance operations to ensure readiness for safe use. This minimum standard is important for upholding safety protocols and regulations in propane gas systems, thereby protecting users from hazardous leaks or failures.
