Price based on 15 pages Foreword ISo (the International Organization for Standardization) is a worldwide federation of national standards institutes (ISo member bodies). The work of deveioping Inter- national Standards is carried out through iSo technical committees. Every member body interested in a subject for which a technical committee has been set up has the right to be represented on that committee. International organizations, governmental 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 ISoO Council. International Standard ISo 1005/7 was developed by Technical Committee ISO/TC 17, Steel, and was circulated to the member bodies in May 1981. ft has been approved by the member bodies of the following countries : Austria Italy Sweden Belgium ueder Switzerland China Korea, Dem.

NOTE In many cases, the operations by which the components are made ready for assembly, such as the final machining operations of the wheel seats of the axles and of the bores of the wheels and the 2 References mounting of the tyres on the wheel centres, are carried out by the wheelset manufacturer and are consequently to be regarded as a part ISO/R286,iSO systemof limits and fits-Part1:General, of the manufacture of the wheelset.
