4.3.1.8 If a bilge pump is of a type fitted with a removable discharge hose, the hose shall be secured to the pump by a means which enables removal of the hose by hid, with a tool that is secured to the pump by a chain or cable, or a tool wh.ch is available in the tool kit (see 4.44). The discharge hose shall have an inside diameter not less than that of the pump discharge opening.
4.3.2 TestIng
4.3.2.1 The bilge pump being tested shall be set up at a height of 1,2 m over a source of water for operation with all the required fittings and connections, the set-up to simulate an installation in a lifeboat. The bilge pump shall be operated, without manual priming, at a speed of fifty cycles per minute, and the flow of water measured. The time to first discharge of water shall not exceed 1 mm. and the discharge rate after the first discharge of water shall not be less than that required by 4.3.1.1.
4.3.2.2 A pressure gauge capable of registering 140 kPa, and a variable restriction (nozzle. valve, etc.) shall be fitted in the discharge line. The pump shall be put in operation with the discharge line open, and Ihen the restriction shall be gradually closed until the pressure builds up to at least 140 kPa. This pressure shall be maintained for at least 15 s, after which the pump shall be disassembled and inspected. There slid be no destruction or deformation ol parts sufficient to affect the serviceability of the pump as a result of this test.
4.3.2.3 Wh the pump firmly secured in such a position that the shaft or operating lever is fully extended and ri a horizontal position, apply a downward load of 90 kg for a period of 5 mm at the free end of the shaft or operating lever and perpendicular to its axis and the axis of the shaft. There shall be no slippage of the lever around the shaft, nor any evidence of permanent set or undue stress in any part of the pump, In cases where the design of the pump is such that this test may not be applicable to the complete pump, the pump shall be disassembled and the 90 kg load applied to the shaft or operating lever while the free end is held in a vice or chuck so that the shaft or operating lever is in a horizontal position.
