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

The expected duration for a standing pressure test is typically 24 hours. This time frame allows for an adequate observation period to assess the integrity of the system being tested. A longer duration ensures that any potential leaks or pressure variances are detected, as they may not be apparent in shorter testing intervals. The 24-hour period aligns with industry standards, providing sufficient data to analyze the system's performance and ensure reliable results.

In shorter duration tests, such as those of 2, 4, or even 12 hours, any fluctuations or issues may go unnoticed because they may not have enough time to manifest or stabilize. Therefore, a comprehensive assessment achieved through a full day of observation emphasizes the importance of thorough testing in ensuring the reliability of pressure containment systems.
