ISO INTERNATIONAL STANDARD 9203-3 First edition 1989-07-01 Shipbuilding - Topology of ship hull structure elements Part 3 : Relations of elements Construction navale - Topologie des élements de structure de coque d'un navire - Partie 3: Relations entre les élements Reference number ISO 9203-3 : 1989 (E) ISO9203-3:1989(E) Foreword ISo (the International Organization 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 has the right to be represented on that committee. International organizations, govern- mental 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. Draft International Standards adopted by the technical committees are circulated to the member bodies for approval before their acceptance as International Standards by the ISo Council. They are approved in accordance with ISO procedures requiring at least 75 % approval by the member bodies voting. International Standard iSO 9203-3 was prepared by Technical Committee ISO/Tc 8, Shipbuilding and marine structures. Iso 9203 consists of the following parts, under the general title Shipbuilding -- Topology of ship hull structure elements: Part 1: Location of elements - Part 2: Description of elements Part 3: Relations of elements ISO 1989 Allrights reserved.
