The committee is mainly responsible for the administrative tasks, and the INTERACT conference. The research activities are mainly concentrated to the working groups. Working groups are organized around special topics. Being active in one of the working groups is also the best way to be involved in the work in TC.13. To join a working group it is necessary to contact the chair or secretary of the working group.

New working groups can also be proposed to the committee, if there is an appreciable need for work in the new area. This proposal has to be submitted to the committee, to be decided upon by the committee during a business meeting.
