NOTE 3: While these classifications will be used by the Standards Council to achieve a balance for Technical
Committees, the Standards Council may determine that new classifications of member or unique interests need
representation in order to foster the best possible Committee deliberations on any project. In this connection, the
Standards Council may make such appointments as it deems appropriate in the public interest, such as the
classification of “Utilities” in the National Electrical Code Committee.
NOTE 4: Representatives of subsidiaries of any group are generally considered to have the same classification as
the parent organization.
