17、ion) 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 has the right to be r
18、epresented 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. International Standards
19、 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. Publication as an Internat
20、ional 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 rights. ISO 21005 was
21、prepared by Technical Committee ISO/TC 8, Ships and marine technology, Subcommittee SC 8, Structures. This first edition of ISO 21005 cancels and replaces ISO 1095:1989 and ISO 3254:1989.

43、 edge cover); is the factor obtained from the graph in Figure A.1; b is the dimension of w1 or h1, whichever is less, in millimetres; p is the pressure, in kilopascals.
