The work of preparin
23、g 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, governmental and non-governmental, in liai
24、son 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 voting. Publicatio
25、n as an International Standard requires approval by at least 75% of the member bodies casting a vote. International Standard ISO5620-2 was prepared by Technical Committee ISO/TC8, Shipbuilding and marine structures. This first edition of ISO5620-2 together with ISO5620-1 cancel and replace the first
26、 edition of ISO5620, of which they constitute a technical revision.
