FOREWORD IS0 (the International Organization for Standardization) is a worldwide federation of national standards institutes (IS0 Member Bodies). The work
2、 of developing International Standards is carried out through IS0 Technical Committees. Every Member Body inter- ested in a subject for which a Technical Committee has been set up has the right to be repre- sented on that Committee. International organizations, governmental and non-governmental, n l
3、iaison 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 the IS0 Council. International Standard IS0 2301 was drawn up by Technical Committee I
