HYDROSTATIC HEAD PRESSURE RESISTANCE - 60 METRE (6 BAR)
1. Superswell 47B has been tested with potable and salt water to
®
withstand a hydrostatic head pressure resistance of 60 metres (6.0
Bar) without any water leakage or pressure drop.
2. The testing was undertaken twice with a one month dry cycle in
between the 1st and 2nd test to simulate a wet and dry cycle of the
joint.
3. The above testing was conducted by an independent testing
laboratory and a copy of the test report is available upon request.
