12、zation for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been establishe
13、d has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
14、International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Pub
15、lication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent
16、 rights. ISO 15516 was prepared by Technical Committee ISO/TC 8, Ships and marine technology, Subcommittee SC 4, Outfitting and deck machinery. This first edition cancels and replaces ISO 6067:1985, which has been technically revised. BS ISO 15516:2006 Licensed Copy: sheffieldun sheffieldun, na, Sun
17、 Nov 26 14:30:16 GMT+00:00 2006, Uncontrolled Copy, (c) BSI v Introduction This International Standard which forms a code of practical interpretation and amplification of the requirements of the CONVENTION FOR THE SAFETY OF LIFE AT SEA (SOLAS), deals with both winches and davits for lifeboats to pro
18、vide an identical basis for design, manufacture and acceptance of Launching appliances for davit-launched lifeboats for use by ship-owners, shipbuilders and appropriate organizations. This International Standard incorporates and revises the requirements of ISO 6067 and, as such, replaces ISO 6067 in
19、 its entirety. Launching appliances for free-fall lifeboats are not covered by this standard because of their different methods of launching, recovery and stowage. Considering the convenience in practice, this standard specifies some values, such as the minimum speed of recovering light-loaded lifeb
20、oats by power (when necessary) and the recovery speed of unpowered winch, which are not required by SOLAS but have been given in ISO 6067. This International Standard is also applicable to launching appliances for fast rescue boats on ro-ro passenger ships. This International Standard is mainly base
21、d on AMENDMENTS from 1983 to 1996 to SOLAS 1974 and IMO RESOLUTIONS and protocols concerned, especially MSC.47(66) AMENDMENTS TO THE INTERNATIONAL CONVENTION FOR THE SAFETY OF LIFE AT SEA 1974, MSC.48(66) INTERNATIONAL LIFE-SAVING APPLIANCE CODE and MSC.81(70) LIFE-SAVING APPLIANCE TEST.
