The Standards Committee

The IES Standards Committee is responsible for overseeing the process by which IES Standards are developed. As an accredited American National Standards Institute (ANSI) Standards Developing Organization, the IES must follow the ANSI Essential Requirements for arriving at consensus based standards. The Standards Committee is dedicated to ensure that the process of committee selection is fair, open, balanced, non-commercial, and provides due process for all stakeholders. There are six at-large committee members, plus the three Chairs of the Lighting Science, Lighting Practice, and Lighting Applications Advisory Panels. All members are approved by the IES Board of Directors, and there are two Board Liaisons that work with the Standards Committee on issues of policy when needed.
