30、tertight door is to be fitted onto the dedicated pressure test box. Increase the water pressure inside the box to 0,1 MPa and keep it for 5 min, then discharge the pressure. No leakage or permanent deformation shall exist on the door.The maximum test pressure is 0,1 MPa. Test pressure shall be in ac
31、cordance with the location of each watertight door.As per the full-scale ship installation condition, the watertight door is to be well fitted onto the pressure test box and is to be closed. A hose test is to be conducted under the pressure not less than 0,2 MPa with a nozzle diameter not less than
32、12,5 mm. Flushing operation is to be made towards the sealing strap from a distance not exceeding 1,5 m. No water leakage shall exist.Apply powder uniformly on the door frame, close the door and then open it. The indent pressed on door plate shall be uniform and continuous: contact width 5 mm, compr
33、ession depth 4 mm.6.2 15 inclined testThe watertight door is installed on a simulated device. From both sides, push the watertight door manually inclined to any side (front, rear, left, right) by 15 (see Figure 5). The test result shall be that the door is able to proceed with “closed-open-closed” m
