The work of preparing International Standards is normally carried out
12、 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 col
13、laborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3. Draft International Standards adopted by the technical committees a
14、re 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 Standard ISO 8443 was prepared by Technical Committee ISO/TC 4, Rolling bearings. This second edition cancels and replaces the
15、 first edition (ISO 8443:1985) which has been technically revised. In particular references to a revised version of ISO 492 have been updated.

All other boundary dimensions for comp
17、lete bearings are given in ISO 15. Tolerances for the flanges are given in ISO 492. For instrument precision bearings, all tolerances are specified in ISO 1224. 2 Normative references The following normative documents contain provisions which, through reference in this text, constitute provisions of
18、 this International Standard. For dated references, subsequent amendments to, or revisions of, any of these publications do not apply.
