14、on 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 established ha

15、s 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. Inte

16、rnational Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the m

17、ember bodies casting a vote. Attention is drawn to the possibility that some of the elements of this International Standard may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. International Standard ISO 15372 was prepared by Technical

18、 Committee ISO/TC 8, Ships and marine technology, Subcommittee SC 1, Lifesaving and fire protection. BSISO15372:2000 v Introduction This International Standard is intended to supplement International Maritime Organization (IMO) requirements for rescue boats used on ships complying with the 1974 Safe

19、ty of Life At Sea Convention (SOLAS 74), as amended. BSISO15372:2000INTENRATIONAL TSANDADR ISO 27351:(0002)E1 Ships and marine technology Inflatable rescue boats Coated fabrics for inflatable chambers 1 Scope This International Standard specifies the minimum requirements for coated fabrics, and test

20、 procedures for those fabrics, for use in the construction of inflatable chambers of rescue boats complying with the 1974 Safety of Life at Sea Convention (SOLAS), as amended; Chapter I, paragraph 1.2, and Chapter V of the International Life-Saving Appliance Code IMO Resolution MSC.48 (66); and the

21、IMO Assembly resolution A.689(17), as amended. These coated fabrics consist of a base textile with a synthetic elastomeric or plastomeric compound applied to one or both faces. Requirements for fabrics for inflatable boats other than SOLAS rescue boats are contained in ISO 6185:1982, Shipbuilding an

22、d marine structures Inflatable boats Boats made of reinforced elastomers or plastomers. 2 Normative references The following normative documents contain provisions which, through reference in this text, constitute provisions of this International Standard.
