Price based on 2 pages Copyright International Organization for Standardization 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 1so Technical Committees. Every Member Body interested in a subject for which a Technical Committee has been set up 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. 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 resuits of the work of the Technical Committees were published as Iso Recommendations; these documents are now in the process of being transformed into International Standards. As part of this process, Technical Committee ISO/TC 97 has reviewed iSO Recommendation R 1154 and found it technically suitable for transformation. International Standard ISO 1154 therefore ISO Recommendation R 1154 was approved by the Member Bodies of the foflowing countries : Germany Australia Spain Belgium Greece Sweden Brazil Italy Switzerland Canada Japan Thailand Netherlands United Kingdom Czechoslovakia Denmark New Zealand U.S.A. Egypt, Arab Rep. of Poland France Romania No Member Body expressed disapproval of the Recommendation. No Member Body disapproved the transformation of ISO/R 1154 into an International Standard.
