What is the standard test duration for a hydrostatic flow test in fire sprinkle systems?

The standard test duration for a hydrostatic flow test in fire sprinkler systems is indeed 2 hours. This length of time is specified to ensure that the system can withstand the test pressures without any leakage or failure at the joints and connections. The 2-hour duration allows for a thorough assessment of the integrity of the system under pressure and ensures that any potential weaknesses can be identified. This testing period is crucial for maintaining safety standards and ensuring that fire sprinkler systems are reliable when needed in an emergency.

Additionally, this specific timeframe is consistent with the guidelines provided in industry standards, ensuring that the test is comprehensive enough to detect any issues while also being practical for installation and maintenance workflows. In contrast, shorter or longer testing durations may not provide sufficient verification of the system's reliability under operational conditions.
