What is the minimum pressure test level required regardless of design pressure?

The minimum pressure test level required, regardless of design pressure, is 3 psig. This value is established to ensure that all propane systems are tested adequately to verify their integrity and leak-tightness under pressure. A minimum of 3 psig helps to ensure safety in the installation and operation of propane systems, allowing for the detection of any potential leaks or weaknesses in the piping or equipment.

Using a pressure test level below this minimum could fail to adequately identify issues that could lead to serious safety hazards, such as leaks or system failures during operation. Therefore, maintaining the 3 psig standard is a critical step in the propane safety protocol and compliance with regulatory requirements. This standard applies universally to all propane systems to ensure a baseline level of safety and reliability.
