U.S.-Held ISO Secretariats

  1. ISO
  2. ANSI ISO Activities
  3. U.S.-Held ISO Secretariats


For each International Organization for Standardization (ISO) Technical Committee (TC) or Subcommittee (SC), one member country holds the Secretariat, providing administrative leadership for the activity.

The United States currently holds more than 100 ISO or joint ISO/IEC TC and SC Secretariats (see separate page for information on ISO/IEC Joint Technical Committee 1). There must be a U.S. Technical Advisory Group (TAG) for each committee for which the U.S. holds a Secretariat.

ANSI-Administered Secretariats

In the majority of cases, ANSI delegates ISO committee Secretariats to other U.S. organizations with expertise and engagement in a particular industry sector. But ANSI staff does directly administer a number of Secretariats at the request of specific industries or other ANSI constituents; see ANSI-Administered Secretariats.

For information on the processes by which U.S.-held ISO Secretariats are delegated and administered, as well as their responsibilities and oversight, see sections 1.5, 1.6, and 1.7 (including subsections) of the ANSI International Procedures.
