Price based on 5 pages Not for Resale FOREWORD ISO (the International Organization for Standardization) is a worldwide federation of national standards institutes (Iso Member Bodies). The work of developing International Standards is carried out through ISo Technical Committees. Every Member Body interested in a subject for which a Technical Committee has been set governmental and non-governmental, in liaison 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 ISO Council. Prior to 1972, the results of the work of the Technical Committees were published transformed into International Standards. As part of this process, Technical Committee ISO/TC 82 has reviewed ISO Recommendation R 1717 and found it suitable for transformation. International Standard ISO 1717 therefore replaces ISO Recommendation R 1717-1970.
