This International Standard specifies performance and use of various items of survival equipment carried in survival craft and rescue boats complying with the International Convention for the Safety of Life at Sea, 1974 (as amended), and the International Maritime Organization Life-Saving Appliance Code. For many items, it also includes guidelines for maintenance and periodic inspections by Administrations or ships' crews in informative Annex A.

The following normative documents contain provisions which, through reference in this text, constitute provisions of this International Standard. For dated references, subsequent amendments to, or revisions of, any of these publications do not apply. However, parties to agreements based on this International Standard are encouraged to investigate the possibility of applying the most recent editions of the normative documents indicated below. For undated references, the latest edition of the normative document referred to applies. Members of ISO and IEC maintain registers of currently valid International Standards.

For the purposes of this International Standard, the following terms and definitions apply.

　

The Government of the State whose flag a ship is entitled to flymarked with approval markings of a flag Administration or a recognized organization acting on its behalf

A bailer shall be buoyant, and if its purpose is not immediately apparent, clearly marked with its function in the appropriate language or languages. It shall have a capacity of at least [1 l], and shall be fitted with a lanyard of suitable length for the craft in which it is intended to be used. For bailers for use in inflatable or inflated craft, the bailer should not contain any sharp or pointed edges which could damage inflated chambers. [Capacity? Strap or handle? Lanyard? Designed so as not to potentially harm the survival craft or rescue boat?]

4.2.1 A bilge pump shall be manually operated, either oscillating, wing type, or full rotary type, and shall be so arranged as to permit attachment to a thwart or other part of the lifeboat structure without interfering with seating.[A bilge pump for a lifeboat of less than 70 persons capacity shall have a capacity of at least 6 gallons per minute at 50 double strokes. A bilge pump for a lifeboat of 70 persons or greater capacity shall have a capacity of at least 15 gallons] per minute at 50 double strokes.] [The discharge rate shall be not less than 23 liters per minute for a lifeboat of less than 7.3 m in length, and not less than 32 liters per minute for a lifeboat of over 7.3 m in length.]

　

　

4.2.2 Bilge pumps shall be of rugged construction, of first classproper workmanship in every respect, and free from any defects affecting serviceability. The materials used shall be of good quality and suitable for the purpose intended, and shall be demonstrated by a salt spray test or equally effective means to be corrosion-resistant or protected against corrosion by acceptable means. However, parts subject to wear shall not depend upon coatings for corrosion resistance.

　

4.2.3 Bilge pumps shall be capable of operating against a head pressure of [20 pounds per square inch] when tested in accordance with 4.2.9.

　

4.2.4 The bilge pump body shall be provided with a removable cover plate or plates to allow for inspection or cleaning.

　

4.2.5 The operating lever shall have a steel or bronze core through its entire length, but for comfort may have a gripping surface of wood or other suitable material. The lever shall be removable and shall be attached to the pump shaft by means of a set screw or equivalent means, and further shall be connected to the pump body or shaft end by a retaining chain to prevent loss.

　

4.2.6 The suction line shall be fitted with an intake check valve and a suitable strainer. The strainer shall be removable for cleaning without the use of tools. The suction line shall contain no hose or fittings subject to collapsing when the pump is in service.

　

4.2.7 Discharge outlets shall be provided with a corrosion-resistant tee, with a removable plug at the top for priming, which shall be secured to the tee by a retaining chain. The bottom of the tee shall be fitted with pipe threads or other equally effective means to fit the discharge outlet of the pump, and the discharge portion of the tee shall be a plain clamp type male hose connection with inside diameter not less than that of the pump discharge opening.

　

4.2.8 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 priming, at the standard speed specified for its size, and the flow of water measured. The time to first discharge of water shall not exceed one minute, and amount of water discharged the discharge rate after the first discharge of water shall not be less than that required by 4.2.1.

　

4.2.9 After the successful completion of the test outlined in 4.2.8, a pressure gage capable of registering [20 pounds per square inch], and a variable restriction, such as a nozzle, valve, etc., shall be fitted in the discharge line. The pump shall be put in operation with the discharge line open, and then the restriction shall be gradually closed until the pressure builds up to at least [20 pounds per square inch]. This pressure shall be maintained for at least 15 seconds, after which the pump shall be disassembled and inspected. No destruction or deformation of parts sufficient to affect the serviceability of the pump shall be permitted as a result of this test.[The pump shall not show any leakage when a water pressure of 1 kgf/cm² (approx. 14 psi) is applied for 30 seconds.]

　

4.2.10 With the pump firmly secured in such a position that both the shaft and operating lever are in a horizontal position, apply a downward load of [200 pounds90 kg] for a period of 5 minutes at the free end of the 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 [200-pound90 kg] load applied to the shaft and operating lever while the free end of the shaft is held in a vise or check so that both the shaft and the operating lever are in a horizontal position.

　

4.2.11 Each pump shall be permanently and legibly marked with the name of the manufacturer, the capacity, and appropriate approval information. The tee required by 4.2.7 shall be permanently and legibly marked with the words ''PRIME HERE''.

The boathook should be of the single hook and ball point style. In addition, for boathooks intended for use with inflated rescue boats or rigid inflated rescue boats, the boathook shall be of a safety type designed to minimize the possibility of damage to the inflated portions of the hull. The tip shall be securely fastened to the handle. The handle length should be at least 2.4 m long, except that for boats 9 m long or longer, the handle should be at least [3.6 m] long. Handles should be at least 38 mm diameter in order to be properly gripped. The boathook shall be buoyant.[Investigate weight/buoyancy requirement? What is current practice?]
