What is the maximum allowable pressure drop for a gas line during a pressure test?

The maximum allowable pressure drop for a gas line during a pressure test is 10% of the original pressure. This standard is set to ensure safety and the integrity of the gas piping system. By limiting the pressure drop to 10%, it helps to detect any leaks or weaknesses in the gas line while maintaining a reasonable margin that allows for safe operational conditions. If the pressure were to drop more than this, it could indicate a significant problem within the system that needs addressing. This 10% threshold has been established based on industry standards and practices, ensuring that all gas installations remain safe and reliable for users.
