Part of the strength of 18.102 (water pressure)
18.102.1 For use Bourdon tube, flexible metal bellows or diaphragm, etc., and there is no case of rated pressure 2000kPa or greater
The pressure-sensitive controller, the controller should be equal to the maximum withstand pressure test 1min four times the rated working pressure without bursting.
Test controllers should be connected to the hydraulic pump irrigation exclude air. The pressure slowly rise to the desired value.
During the test, if the leak did not occur in 50% of the required test pressure or less, and the test can be continued until 4 times the maximum rated
When the working pressure, leakage, or gasket with the Department are allowed.
18.102.2 For the Bourdon tube, flexible metal bellows or diaphragm member, member assembly within the housing pressure-sensitive controllers, shall comply
18.102.1 housing requirements, or should be.
--- Withstand twice the maximum rated working pressure of the hydraulic pressure test 1min without visible leakage, and
--- Withstand four times the maximum working pressure test 1min or if due to the damage of the equipment and pressure less than four times, at least by
That is three times the maximum rated pressure. But also to show that the housing can ease the pressure of four times the maximum rated pressure, but there is no harm surrounding
Any damage to people or the environment or show casing can withstand the test pressure.
This test is carried out according to 18.102.1.
18.102.3 voltage limiter or pressure cut-off device should be able to withstand the maximum rated working pressure equal to four times the water pressure of 1min without damage.
So that water-filled test controller connected to the removal of air and water pumps. Slowly increase the pressure required test pressure.
