IsO and IEC technical committees collaborate in fields of mutual interest. Other international organizations, governmental and non-governmental, in liaison with IsO and IEC, also take part in the work. In the field of information technology, IsO and IEC have established a joint technical committee, ISO/IECJTC1. The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1.
