Acceptance tests require the test pressure to be maintained without loss for how long?

Acceptance tests require the test pressure to be maintained without loss for how long?

• A. 2 hours
• B. 1 hour
• C. 30 minutes
• D. 4 hours

Answer: (A)

When acceptance testing a foam-water sprinkler system, the test is meant to show the system can hold the designated test pressure without dropping. Maintaining pressure for a specific period helps reveal any leaks in piping, fittings, valves, or other components, and confirms the system can stay pressurized under service conditions. The required duration for this test is two hours. This time frame is long enough to expose slow leaks that might not appear in shorter tests, providing confidence that the system will perform reliably in actual use. Shorter periods, like one hour or 30 minutes, could miss gradual losses, while an excessively long duration isn’t necessary for the purpose of the acceptance test.
