ISO INTERNATIONAL STANDARD 6697 First edition 1994-11-15 Cycles - Hubs and freewheels - Assembly dimensions Cycles - Moyeux et roues libres - Dimensions d'assemblage so Reference number ISO 6697:1994(E) Not for Resale ISO 6697:1994(E) Foreword Iso (the International Organization for Standardization) is a worldwide federation of national standards bodies (lsO member bodies). 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, governmental and non-governmental, in liaison with IsO, also take part in the work. IsO collaborates closely with the International Electrotechnical Commission (lEC) 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 International Standard requires approval by at least 75 % of the member bodies casting a vote. International S Standard ISO 6697 was prepared by Technical Committee ISo/TC 149, Cycles, Subcommittee SC 2, Sub-assemblies and compo- nents.
