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, governmental and non-governmental, in
liaison with ISO, also take part in the work. ISO collaborates 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 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.
Attention is drawn to the possibility that some of the elements of this International Standard may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights.
International Standard ISO 9001 was prepared by Technical Committee ISO/TC 176, Quality management and
quality assurance, Subcommittee SC 2, Quality systems.
This third edition of ISO 9001 cancels and replaces the second edition (ISO 9001:1994) together with
ISO 9002:1994 and ISO 9003:1994. It constitutes a technical revision of these documents. Those organizations
which have used ISO 9002:1994 and ISO 9003:1994 in the past may use this International Standard by excluding
certain requirements in accordance with 1.2.
The title of ISO 9001 has been revised in this edition and no longer includes the term “Quality assurance”. This
reflects the fact that the quality management system requirements specified in this edition of ISO 9001, in addition to
quality assurance of product, also aim to enhance customer satisfaction.
