Fo rewo rd
IS0 (the International Organization for standardization) is a worldwide federation of
national standards bodies (IS0 member bodies). The work of preparing International
Standards is normally carried out through IS0 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-
menial and non-governmental, in liaison with ISû, also take part in the work. IS0
collaborates closely with the International Electrotechnical Commission KC) on ail
matters of electrotechnical standardization.
Draft International Standards adopted by the technical committees are circulated to
the member bodies for approval before their acceptance as International Standards by
the IS0 Council. They are approved in accordance with IS0 procedures requiring at
least 75 % approval by the member bodies voting.
International Standard IS0 6429 was prepared by the European Computer Manufac-
turers Association (as Standard ECMA4) and was adopted, under a special "fast-
track procedure", by Technical Committee ISO/TC 97, Information processing
systems, in parallel with its approval by the IS0 member bodies.
This second edition cancels and replaces the first edition (IS0 6429 : 19831, of which it
constitutes a full revision.
Annexes A, B, C, D and E of this International Standard are for information only.
