introduction
ISO (International Organization for Standardization) is a global federation of national standards bodies (ISO member bodies). The development of international standards is usually carried out through ISO technical committees. Each member group interested in a subject for which a technical committee has been established has the right to be represented on the Committee. International organizations, governments and non-governmental organizations in contact with ISO are also involved in this work. ISO works closely with the International Electrotechnical Commission (IEC) on all matters of electrical standardization.

Part 1 of the ISO/IEC Directive describes the procedures used to develop this document and for further maintenance. In particular, attention should be paid to the different approval criteria required for different types of ISO documents. This document has been drafted in accordance with the editorial rules of ISO/IEC Directive Part 2 (see iso.org/directives).

Please note that some elements of this document may be the subject of patent rights. ISO is not responsible for identifying any or all such patents. Details of any patent rights identified during the development of the document will be found in the introduction and/or list of ISO Patent declarations received (see iso.org/patents).
