Price based on 3 pages 3876~86 h629200 E06759 Foreword Iso (the International Organization for Standardization) is a worldwide federation of national standards bodies (Iso member bodies). The work of preparing International 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. 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 3876 was prepared by Technical Committee ISO/TC 8, Shipbuilding and marine structures. This second edition cancels and replaces the first edition (ISo 3876-1977), of which it constitutes a minor revision. Users should note that all International Standards undergo revision from time to time and that any reference made herein to any other International Standard implies its latest edition, unless otherwise stated. @ International Organization for Standardization, 1986 Printed in Switzerland 9-92 4851903 0028795 9 INTERNATIONALSTANDARD ISO3876-1986 (E) Shipbuilding - Inland vessels -- Hand-holes 1 Scope and field of application Dimensions inmillimetres (Values for size II in parentheses) This International Standard specifies the dimensioris and Coaming, angles L40 × 40 × 5 designs of watertight and oiltight hand-holes for inland vessels.
