21、6 Foreword IS0 (the International Organization for Standardization) is a worldwide federation of national standards bodies (IS0 member bodies). The work of preparing International Standards is normally carried out through IS0 technical committees. Each member body interested in a subject for which a
22、 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 pari in the work. IS0 collaborates closely with the International Electrotechnical Commission (IEC) on all mat
23、ters of electrotechnical standardization. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an inter- national Standard requires approval by at least 75% of the member bodies casting a vote. International Standard IS0 562
24、0-2 was prepared by Technical Committee ISO/TC 8, Shipbuilding and marine structures. This first edition of IS0 5620-2 together with IS0 5620-1 cancel and re- place the first edition of IS0 5620, of which they constitute a technical revision. IS0 5620 consists of the following parts, under the gener
