An addendum to the original Dual Logo Agreement for the International Electrotechnical Commission (IEC) and the Institute of Electrical and Electronics Engineers (IEEE) permits joint development of projects in both organizations, leading to IEC/IEEE standards.

The original October 2002 agreement, describes a procedure for submitting and approving existing IEEE standards to IEC. The first standard completed under the IEC/IEEE dual logo agreement was published in May 2004.

The addendum establishes procedures for IEC and IEEE to jointly develop standards, the process of which includes consulting to establish the need for new standards projects, initiating a joint development project, preparing and circulating draft standards, and voting to approve those standards. It also includes processes for maintenance of approved standards to keep them up to date, as well as details on publication, copyright, and sales.

The new agreement is seen as a critical step toward development of future standards that will be accepted by the global technical community.
