Foreword ISo (the International Organization for Standardization) is a worldwide federation of national standards bodies (Iso 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, govern- mentaf 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 least 75 % approval by the member bodies voting. International Standard ISO 4863was prepared by Technical Committee ISO/TC 108, Mechanical vibrationand shock.
