During a standing pressure test, what is the expected duration?

The expected duration for a standing pressure test is typically 24 hours. This extended period allows for a thorough assessment of the system’s ability to maintain pressure over time, ensuring that any potential leaks or weaknesses can be identified. During this testing phase, continuous monitoring provides data that reflects the system's integrity under sustained conditions, which is critical for ensuring safety and reliability.

Other durations, such as 2 hours, 4 hours, or 12 hours, may not provide sufficient time to capture fluctuations or subtle weaknesses that could lead to failures in the system. While shorter tests might reveal immediate issues, they do not account for long-term stability, which is essential for more comprehensive evaluations or compliance with industry standards. Therefore, a duration of 24 hours is standard for effectively validating the pressure system's performance.
