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 reprented on that committee. Interna
tional organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates cloly 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 2.
The main task of technical committees is to prepare International Standards. 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.
In other circumstances, particularly when there is an urgent market requirement for such documents, a technical committee may decide to publish other types of document:
⎯ an ISO Publicly Available Specification (ISO/PAS) reprents an agreement between technical experts in an ISO working group and is accepted for publication if it is approved by more than 50 % of the members
of the parent committee casting a vote;
⎯ an ISO Technical Specification (ISO/TS) reprents an agreement between the members of a technical committee and is accepted for publication if it is approved by 2/3 of the members of the committee casting
a vote.
An ISO/PAS or ISO/TS is reviewed after three years in order to decide whether it will be confirmed for a further three years, revid to become an International Standard, or withdrawn. If the ISO/PAS or ISO/TS is confirmed, it is reviewed again after a further three years, at which time it must either be transformed into an International Standard or be withdrawn.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.

This part of ISO 128 has been established to specify rules and guidance for the u of the simplified reprentation on mechanical engineering drawings.
It is not the purpo of the simplified reprentation to prent difficulties in understanding the drawing. When its u could prent such difficulties, it is intended that a complete reprentation in accordance with the basic rules of ISO 128 be ud.
