ISO 4001:1977 pdf download. Shipbuilding — Inland navigation — Raft-type life-saving apparatus.
The adoption of the operational and technical requirements for raft-type life-saving apparatus (see the figure) specified in this International Standard will promote the determination of the basis of their optimum design on the one hand and the establishment of a single viewpoint in respec of providing ships with this kind of life-saving appliance on the other hand.
1 SCOPE AND FIELD OF APPLICATION
1.1 This International Standard specifies the purpose, materials and main technical requirements for rigid(non inflatable) raft-type life-saving apparatus, which may be supplied to inland ships.
1.2 The raft-type life-saving apparatus for the inland ships subject to the provisions of the International Convention for the Safety of Life at Sea, 19601, should comply with the ing requirements of the corresponding requirements of the Convention.
4 CLASSIFICATION
The groups into which the apparatus are divided depending on the number of persons supported as well as the materials from which they may be manufactured and the means which ensure their buoyancy are indicated in the table.
5 OPERATIONAL AND TECHNICAL REQUIREMENTS
5.1 The apparatus shall be of such construction that it retains its shape and properties under various weather conditions while staying on deck as well as in the water at an ambient air temperature ranging from -30°C to+65℃。
5.2 The apparatus shall be of such strength that it can be dropped into the water from a 10 m height without being damaged.
5.3 The capacity of the air compartments or the volume of the materials of equivalent buoyancy within every apparatus shall provide:
a) balance on the water under all possible loading
conditions;
b) support for the specified number of persons on condition that not less than 0.014 5 m3 of spare buoyancy of the air compartments or the equivalent volume of the filler is available for each person;ISO 4001:1977 pdf download.
