ISO Foreword
ISO (International Organization for Standardization) is a joint organization of national standards bodies (ISO member bodies) of various countries. The formulation of international standards is usually carried out through a technical committee. If each member body is interested in a certain technical need, it can also participate in the committee. Governmental and non-governmental international organizations related to ISO can also participate in this work. JS) has close links with the International Electrotechnical Commission (IEC) in the field of electrotechnical standardization. [International Standards shall be prepared in accordance with the provisions of Part 3 of the IS0/IEC Directives. Draft International Standards accepted by technical committees are circulated to all member bodies for voting. The official publication of international standards requires a voting membership of at least 100 member bodies.
International Standard TSO 416 was prepared by ISO/TC:2 Technical Committee. This first edition includes major revisions and additions to the second edition (IS) 401e: 1998) to the extent technically appropriate. ISO Introduction
