3、on 3 pages Foreword ISO (the International Organization for Standardization) is a worldwide federation of national Standards bodies (ISO member bedies). The work of preparing International Standards is normally carried out through ISO technical committees. Esch member body interested in a subject fo
4、r 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
5、 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 6043 was prepared by Technical Committee ISO/TC 8, Shipb

8、es, forks and associated bolts or pins for components subject to tension load. 1.2 Eyes, forks and bolts or pins with dimensions according to this International Standard are primarily intended for use on the components of ships cargo handling appliances which are subject to tension loads only (for i
9、nstance, round hole eyeplates, sheave block head fittings, block holders, trunnion pieces for span bearing, turnbuckles). 1.3 This International Standard is not applicable to com- ponents subject to compressive thrust or torsional loads (for instance fork-type derrick heel fittings which connect wit
10、h gooseneck Pins). 4 Nominal size The nominal size designation of an eye and fork assembly is a numerical value without unit for reference purposes; it is derived from the permissible load in kilonewtons. 5 Dimensions and tolerantes 5.1 Main dimensions The dimension of eye and fork assemblies shall
11、be in accord- ante with the figure and the table. NOTE - The type of bolt or pin to be used and its securing are left to national regulations. 5.2 Tolerantes Dimensional tolerantes shall correspond to the Standard tolerante grade IT 14 given in ISO 286. 2 References 6 Material ISO 286, ISO System of

13、s For the purposes of this International Standard, the definitions given in ISO 8147 apply. Eyes and forks shall be made of steel to ISO 630, grade Fe 360 (as minimum quality). 6.2 Bolts or pins Bolts or pins shall be made of steel to ISO 630, grade Fe 430 (as minimum quality). . 6.3 Higher quality
