Accredited Standards Committee X3

Technical Committees


OMC is the advisory committee to X3 that manages the standardization process within the X3 Technical Committees (TCs). Specific information about OMC meeting dates and liaison assignments (e.g., who is the OMC liaison to X3B5?) can be obtained from the OMC/SD-2, Liaison Information.


X3's standards are developed by its technical committees. A brief description of each TC -- and a technical contact for each -- follows.
