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 voting. Publication as an Inter- national Standard requires approval by at least 75 % of the member bodies casting a vote. International Standard iso 5620-1 was prepared by Technical Committee ISO/TC 8, Shipbuilding and marine structures. This first edition of ISO 5620-1 together with ISO 5620-2 cancel and re- place the first edition of iso 5620, of which they constitute a technical revision. isO 5620 consists of the following parts, under the general title Shipbuilding and marine structures - Filling connection for drinking water tanks: Part 1: General requirements Part 2: Components C ISO1992 All rights reserved.
