The 10 Minute Test
The 10 Minute Test can produce accurate results by recording the pressure loss for just 10 minutes. A specialist pump with a pre-set regulating valve adds the necessary amount of water to the pipeline to maintain system test pressure (STP). The amount of water added is recorded to indicate the pressure changes within the pipeline. For a pipeline to pass a 10 Minute Test, the joints must also be visually inspected for leakage during the test period.
